Important Fitment Notes

* Compact and midsize trucks require the Moto Offset Kit for proper dirt bike clearance and tailgate operation. On these models, dirt bikes may need to be positioned slightly sideways to fully close the tailgate.

** Ford Maverick requires the Moto Offset Kit and may have limited tailgate clearance depending on the specific configuration.

What is the Big Days Deck Rail Kit, and do I need it?

Some Toyota, Nissan, and select other pickup trucks come equipped with a factory Deck Rail System (also called a utility track system). This system features an aluminum channel mounted underneath the bed rails, allowing factory tie-down cleats and accessories to slide along the track.

If your truck has adjustable tie-down points, cargo cleats, or handles that slide within a rail along the inside of the bed, you likely have a Deck Rail System.

How Do I Know If My Truck Has a Deck Rail System?

Common trucks that may have a Deck Rail System include:

  • Toyota Tacoma
  • Toyota Tundra
  • Nissan Frontier
  • Nissan Titan
  • Select other truck models with factory utility tracks

Look along the inside top edge of your truck bed. If you see a rail with sliding tie-down anchors or cleats, your truck has a Deck Rail System.

Do I Need the Deck Rail Kit?

Yes. If your truck is equipped with a Deck Rail System, the Big Days Deck Rail Kit is required for proper Chase Rack installation. The kit includes specialized mounting brackets that work with your truck's existing rail system, ensuring secure and stable mounting without drilling into the bed.

Can you use a Tonneau Cover with the Big Days Chase Rack?

Yes, many tonneau covers are compatible with the Big Days Chase Rack, but compatibility depends on the cover style and mounting method.

Compatible Tonneau Covers

T-Track Tonneau Covers — Recommended

T-Track-equipped tonneau covers are the easiest and cleanest option. These covers feature integrated accessory tracks that allow the Chase Rack to mount directly using our optional T-Track hardware, with no drilling required.

Soft Roll-Up Tonneau Covers

Many soft roll-up covers are compatible.

If your cover does not have T-Tracks, the rack can typically be mounted directly to the truck bed by drilling mounting holes in the bed rail outside the tonneau cover. To use this mounting method, your truck must have at least 3 inches of flat bed rail available outboard of the cover for the rack risers to sit on.

If the tonneau cover extends all the way to the outer edge of the bed rail, it will not be compatible.

How Long Does It Take to Install the Big Days Chase Rack?

Most customers can install the Big Days Chase Rack in about 30–60 minutes, depending on their truck, mounting method, and experience with basic hand tools.

The rack is designed to be a straightforward installation that can typically be completed in your driveway or garage without any specialized equipment.

What Affects Installation Time?

The total installation time depends on a few factors:

  • Whether you're using the clamp-on or bolt-on mounting option
  • If you're installing accessories at the same time
  • Your familiarity with basic hand tools
  • Whether you're working alone or with a second person

While one person can complete the installation, having a second person available makes lifting and positioning the rack quicker and easier.

What Tools Are Required?

The Chase Rack requires only a few common tools:

  • Included 4 mm Allen wrench
  • 13 mm wrench or socket
  • For bolt-on installation: Power drill and 3/8" drill bit

How Does the Bolt-On Chase Rack Mounting Option Work?

The Bolt-On mounting option provides the most secure way to install your Big Days Chase Rack. This installation method requires drilling directly into your truck bed rails and permanently mounting the rack to the vehicle.

What Is Required?

To install the Bolt-On option, you will need to drill four mounting holes into the top of your truck's bed side rails.

Required drill sizes:

  • Pilot hole: Small drill bit
  • Final hole size: 3/8" (holes may need slight enlargement for final fitment)

Installation Overview

  1. Position the rack risers on the bed rails in your desired location.
  2. Place the front edge of each riser approximately 1 inch behind the truck cab.
  3. Use the two square center mounting holes on each riser as your drilling locations.
  4. Loosely install the upper crossbar between the risers to verify alignment and ensure proper fitment.
  5. Drill pilot holes through the riser mounting holes into the bed rail.
  6. Enlarge the holes to 3/8" diameter.
  7. Install the bolts, washers, and lock washers through the risers into the bed rail.
  8. Tighten all bolts securely.

How much weight can the Big Days Chase Rack carry?

The Big Days Chase Rack is engineered for serious hauling and is rated to support 900lbs pounds of static weight. Its heavy-duty steel risers and aluminum crossbars are designed to handle demanding loads while providing a stable platform for bikes, motorcycles, camping gear, work equipment, and overland accessories.

It's important to remember that the rack's usable carrying capacity while driving is also limited by your truck's bed, payload rating, and the weight distribution of your cargo. Always follow your vehicle manufacturer's payload specifications when loading the rack.

What Can the Chase Rack Carry?

The modular design allows the Chase Rack to securely transport a wide variety of equipment, including:

  • Dirt bikes
  • Mountain bikes and e-bikes
  • Kayaks and paddleboards
  • Ladders and lumber
  • Rooftop tents
  • Coolers and portable fridges
  • Recovery gear
  • Camping equipment
  • Skis and snowboards
  • Overland accessories

Does the Big Days Chase Rack Work with Road Bikes and Triathlon Bikes?

Yes. The Big Days Chase Rack is compatible with road bikes, triathlon bikes, gravel bikes, and cyclocross bikes when used with the Big Days Bike Mount. Many customers regularly transport road-style bicycles using this setup.

Because road and triathlon bikes use narrower tires than mountain bikes, a few simple adjustments can help provide the best fit and protection during transport.

How Does the Bike Mount Work with Road Bikes?

The Big Days Bike Mount secures the bike by the front tire, making loading and unloading quick and eliminating frame contact.

Since road and triathlon tires are significantly narrower than mountain bike tires, we recommend placing a towel or similar padding around the rim and tire. This helps:

  • Fill the extra space created by the narrower tire
  • Protect carbon or alloy rims from rubbing
  • Reduce movement during transport
  • Provide a more secure fit

Does the Big Days Chase Rack Work with Fat Bikes?

Yes. The Big Days Chase Rack can transport fat bikes, but the best mounting option depends on your tire width.

Many fat bikes fit in the standard Big Days MTB Bike Mount. However, if your front tire is too wide to fit the MTB Bike Mount, you can use the Big Days Moto Mount instead.

The Moto Mount is designed to accommodate much wider tires, making it an excellent solution for oversized fat bike tires that exceed the capacity of the standard bike mount.

Which Mount Should I Use for My Fat Bike?

The correct mount depends on your tire size:

  • Standard fat bike tires: Use the Big Days MTB Bike Mount if the tire fits properly.
  • Oversized fat bike tires: Use the Big Days Moto Mount for additional tire clearance.

Does the Big Days Chase Rack Work with Street Motorcycles?

Yes. The Big Days Chase Rack can be used to transport many street motorcycles, provided the motorcycle falls within your truck's payload capacity and the rack's weight limits. When paired with the Big Days Moto Mount, the Chase Rack provides a secure and stable way to haul motorcycles without the need for a trailer.

The Moto Mount provides a stable cradle for the motorcycle's front tire, while the motorcycle is secured using tie-down straps attached to the Chase Rack.

What Types of Street Motorcycles Can It Carry?

The Moto Mount is designed to accommodate any motorcycle tire up to 5 inches wide, allowing many street motorcycles to physically fit the system.

However, Big Days has only tested the Moto Mount with dirt bikes, adventure bikes (ADV), dual-sport motorcycles, and supermotos. While many street motorcycles with tires under 5 inches wide may fit, compatibility and safety cannot be guaranteed for other motorcycle types.

What Tools Do I Need to Install the Big Days Chase Rack?

The Big Days Chase Rack is designed for a straightforward installation and requires only a few basic tools.

Included With Every Rack

  • 4mm Allen wrench

Tools You'll Need

For most installations, you'll need:

  • 13mm wrench or socket (socket preferred for faster installation)

Additional Tools for Bolt-On Installation

If you've selected the Bolt-On mounting option, you'll also need:

  • Power drill
  • 3/8" drill bit

Installation Tip

While it's possible to install the rack yourself, having a second person nearby can make the process much easier—especially when positioning the rack and tightening hardware. As an added bonus, the right helper can provide valuable moral support and occasional comedic entertainment throughout the installation.

What Is the In-Bed Stability Bar (Lower Bar) on the Big Days Chase Rack, and Do I Need It?

The In-Bed Stability Bar, also known as the Lower Bar, is a removable crossbar that mounts between the rack uprights inside your truck bed.

What Does the Lower Bar Do?

Creates a Secure Mountain Bike Mounting System

For mountain bike setups, the Lower Bar is a critical component.

It works with our cam roller straps to secure the bike at a second contact point, creating a stable two-point retention system. The pedals strap directly to the bar, helping eliminate bike sway and keeping your bikes secure during highway travel, off-road adventures, and rough terrain.

The Lower Bar is required for all mountain bike configurations.

Functions as a Gear and Cooler Mount

The Lower Bar also serves as a convenient mounting point for coolers, gear bags, recovery equipment, camp accessories, and other cargo.

Many customers use it as an anchor point for straps and tie-downs, making it a valuable addition to any setup.

How Do I Load a Dirt Bike Into the Big Days Moto Mount?

The Big Days Moto Mount is designed to secure dirt bike transport while keeping your truck bed open for gear and passengers. Depending on your setup and available help, there are several ways to load a dirt bike into the mount.

Option 1: Ramp Load (Recommended)

Using the optional loading ramp is the easiest and most controlled loading method.

How It Works
  1. Position the ramp securely against the truck bed.
  2. Lightly throttle the dirt bike up the ramp and into the Moto Mount tray.
  3. Once the bike is resting in the mount, roll or scoot it forward slightly to create space for ramp removal.
  4. Remove the ramp from the truck.
  5. Slide the bike back into its final position within the Moto Mount.
  6. Secure the bike according to the recommended tie-down procedure.

For most riders, the ramp-loading method offers the quickest and most convenient way to load heavier dirt bikes.

Option 2: Two-Person Load

If you don't have a ramp available, two people can carefully lift and position the bike into the Moto Mount. This method requires coordination and careful handling to avoid dropping or damaging the bike.

How Does the Big Days T-Track System Work?

The Big Days T-Track System is a modular mounting platform built directly into the rack's crossbars, allowing you to securely attach accessories, gear mounts, and bike carriers exactly where you need them.

While T-Tracks may seem like a modern overlanding feature, the system has been widely used in construction, manufacturing, and industrial applications for decades because of its exceptional strength, durability, and versatility.

For us, it was an obvious choice. The T-Track system aligns perfectly with our focus on building rugged, adaptable products that can evolve with your adventures.

What Is a T-Track?

A T-Track is a specially shaped channel integrated into the rack's crossbars.

Inside this channel, specialized T-nuts slide freely to create adjustable mounting points. These T-nuts are designed to lock securely in place when tightened, providing a strong attachment point without requiring drilling or permanent modifications to the rack.

How Do I Use the T-Track System?

  1. Identify the T-Track channel on the crossbar where you want to mount an accessory.
  2. Insert the T-nut into the channel.
  3. Slide the T-nut to your desired position.
  4. Attach your accessory using the T-nut as the mounting point.
  5. Tighten the T-nut securely.

How Do the DIY Utility Brackets (Lumber & Ladder Brackets) Work?

The Big Days DIY Utility Brackets, also known as Lumber & Ladder Mounts, turn your Chase Rack into a highly adaptable cargo-carrying system.

Whether you're hauling lumber from the hardware store, securing a ladder, transporting a cooler, mounting a fridge, or carrying oddly shaped gear, these brackets provide a simple and adjustable way to keep cargo secure.

What Are the DIY Utility Brackets?

The DIY Utility Brackets are adjustable L-shaped brackets that attach directly to the Big Days T-Track system.

Unlike fixed cargo mounts, they can be repositioned anywhere along the rack's crossbars, allowing you to create a custom cargo solution for virtually any load.

How Do the DIY Utility Brackets Work?

The system is intentionally simple:

  1. Attach the brackets to the rack using the integrated T-Track system.
  2. Loosen the mounting hardware slightly.
  3. Slide the brackets to match the width and shape of your cargo.
  4. Tighten the hardware securely.
  5. Use tie-down straps to secure your cargo to the brackets.

Can I carry a Kayak with the Big Days Chase Rack?

Yes. The Big Days DIY Utility Brackets can be configured as an adjustable truck bed kayak rack, providing a secure and versatile way to transport kayaks, canoes, paddleboards, and other long recreational gear.

Unlike dedicated kayak carriers that serve a single purpose, the DIY Utility Brackets use the Big Days T-Track system to create a customizable support system that can be adjusted to fit different boat sizes and cargo configurations.

How Do the DIY Utility Brackets Work as a Kayak Rack?

The brackets mount directly to the Chase Rack crossbars using the integrated T-Track system.

Simply slide the brackets into position to match the width of your kayak, canoe, or paddleboard, then tighten them down to create secure side supports. Once positioned, use cam straps or tie-down straps to secure your watercraft to the rack.

The adjustable design helps keep your kayak centered and stable during transport while allowing you to fine-tune the support points for your specific boat.


Damaged Your T-Track? Just Do a Barrel Roll.

Wife drove into the garage with the bikes still on the rack and messed up your T-slot? Don't even stress, brother.

Go ahead and do a kickflip... and flip your upper bar over. Boom.

We believe in second chances. Thanks to the mirrored design of the Chase Rack's upper bar, you can simply remove it, flip it over, and give it a brand-new life. The opposite side has an identical T-Track, so if one side takes one for the team, you've already got a fresh one waiting.

Why Is the Upper Bar Reversible?

The upper crossbar is built with mirrored T-Tracks on both sides, so accidental damage doesn't automatically mean buying a replacement bar.

Whether it was a low garage door, a tree branch, or just one of those days, flipping the bar is quick, easy, and gets you back to hauling bikes and gear.

Quick Summary

  • Garage door won? It happens.
  • Messed up your upper T-slot? Just flip it.
  • No replacement bar needed.
  • Back to adventures in minutes.
