Upgrading your truck with a T40 Roof Rack is one of the smartest ways to boost your vehicle's cargo-carrying versatility. If you’re hauling gear for work, adventure, or everyday use, the T40 system offers multiple fitment options to match your truck's design and your lifestyle.
But with a few different mounting styles available, how do you know which combo is right for your truck? Let’s break it down so you can make the right call with confidence.
1. Roof Fitment – Rack Only (For Trucks with Roof Bars)
Best if: Your truck already has roof bars installed
Installation: No drilling required
Includes: Roof rack, U-bolts, and mounting brackets
This is the simplest option. If your truck came with factory roof bars (or you’ve installed aftermarket ones), this setup lets you mount the T40 rack directly to them. It’s easy, quick, and doesn’t require any modifications to your truck.
✅ Pros: Fast install, no drilling, easily reversible
⚠️ Consider if: You don’t already have roof bars, you’ll need to get those first
2. Roof Fitment – Rack with Tailored Roof Brackets
Best if: You want a clean, flush look and don’t have or want roof bars
Installation: Requires drilling into the roof depending on your truck’s model.
Includes: Roof rack and custom-fit roof brackets
This setup mounts the rack directly to your roof using specially designed brackets. It’s the most “factory-style” look you can get, and it’s ultra-solid. Perfect for those planning to leave the rack on permanently.
✅ Pros: Strongest roof mount, streamlined design
⚠️ Consider if: You’re okay with drilling into your roof
3. Above Truck Bed – Rack with Mountain Top Shutter Brackets
Best if: You already have a Mountain Top (or similar) roller shutter with raised T-channels
Installation: No drilling, uses the shutter’s existing rails
Includes: Roof rack and mounting brackets
This is a popular option for pickup owners with roller shutters. It lifts the rack above the bed, preserving full bed access while giving you extra storage up top.
✅ Pros: No drilling, keeps bed usable, perfect for dual-use trucks
⚠️ Consider if: You have a different style shutter or no shutter at all
4. Above Truck Bed – Rack with Flat Roller Shutter Brackets
Best if: You have a flat-sided roller shutter with side T-channels
Installation: No drilling required
Includes: Roof rack and mounting brackets
Similar to the above, but made specifically for trucks with flatter tonneau-style roller shutters. Still no drilling, and still gives you full use of your bed below the rack.
✅ Pros: Clean install, no mods needed, maintains bed use
⚠️ Consider if: Your shutter lacks the side T-channels, if you have no T-Channels then this will not fit.
5. Rack with Load Bed Cross Bar
Best if: You don’t have a roller shutter or tonneau cover
Installation: Drilling required into bed rails
Includes: T40 rack and load bed cross bar
This is the go-to option if you have an open bed and want a tough, permanent rack mount. It’s bolted directly into the bed rails for a super-strong fit.
✅ Pros: Strongest bed-mounted solution
⚠️ Consider if: You don’t want to drill into your truck bed
