Westcan Truck Racks, Rail Caps & Rear Racks
A Westcan aluminum truck rack is built from three parts: a cab guard at the front, rail caps along the box rails, and a rear rack at the tailgate. This collection holds the rail caps, rear racks, over-canopy racks and the full-size, compact and rear-rack install kits that join them, all mounted through the truck's existing stake pockets with no drilling into the box. Smooth rail caps are listed for pickups from the 1999 model year forward, in mill finish or black powder coat, covering the F-150, Super Duty, Ranger and Maverick, Silverado and Sierra, Colorado and Canyon, Ram 1500, Tundra, Titan and more. The cab guards themselves are in Headache racks and cab guards.
Aluminum truck rack systems: rail caps, rear racks and canopy racks
Westcan has built these racks in British Columbia since 2001, all in aluminum and all fixed through the factory stake pockets. Buy the three pieces together for a full-length rack that carries ladders, pipe and lumber above the box, or add pieces to what is already on the truck. Rail caps are the largest group here and a common first purchase on their own, because they protect the box rails whether or not the rest of the rack follows.
Two finishes are offered on most parts. Mill finish is bare satin aluminum with no coating, so there is nothing to chip, flake or rust. Black is powder coat over the same aluminum, and where both exist they appear as a Finish option on the product.
Shop truck rack parts by type
Smooth rail caps
Rail caps cover the box rails and give the rack its mounting points along the bed. They are cut per truck and box length: extra short, short, long and dually versions are listed separately, from the 1999 to 2006 Silverado and Sierra to the 2024 and newer Ranger.
Rear racks
The rear rack mounts at the tailgate end and carries the back of a long load. Rear rack install kits are shared across several trucks, for example one kit covers the 2004 and newer F-150, 1999 and newer Super Duty and 2007 to 2022 Tundra, and a stand-alone rear rack install kit lets you run a rear rack without rail caps on the 2019 and newer Ram 1500.
Over-canopy racks
Full size and compact over-canopy racks carry loads above a canopy or service body, with a rack extension, a light duty canopy rack and cross supports available. Install kits are truck-specific, from the Colorado and Canyon compact kit to full size kits for the F-150 and Titan.
Full size and compact install kits
Install kits are listed apart from the racks because the same rack fits several trucks with different kits. Full size kits suit half-ton and heavier pickups; compact kits suit the Colorado, Canyon, Ranger, Maverick, Tacoma and Frontier. The fitment table on each rack names the kit it needs.

Why Westcan truck racks
- No drilling into the box. Every part mounts through the factory stake pockets, and the whole system comes off cleanly.
- Cut per box length. Rail caps are listed by truck, model year and box length, so they meet the bulkhead and tailgate ends properly instead of being trimmed on site.
- Coating-free option. Mill-finish aluminum has nothing to chip and does not rust; black powder coat is there if you want it.
- Builds in stages. Rail caps now, rear rack later, canopy rack when the truck gets a canopy, all from one catalogue with published install times on most parts.
Choosing the right truck rack parts
If you are starting from nothing, buy the cab guard and its install kit first, because that is the piece that fixes fitment. Add rail caps next, then the rear rack. If you run a cab guard without rail caps, add the secondary hold down kit so the rack has a second anchor. Confirm the box length before ordering rail caps; a SuperCrew extra short box and a long box take different caps in the same model year. If the truck carries a crossover tool box, tell us; Westcan makes crossover install kits that let the box sit inside the rack. If you are not sure what fits, contact us with your year, make, model and configuration.
Common questions
Do I have to drill my truck box?
No. The system mounts through the factory stake pockets. Nothing is drilled, and the rack removes cleanly.
Can I buy just the rail caps?
Yes. Rail caps are sold on their own and are a common first purchase. They protect the rails whether or not you add the rest of the rack later.
What is the difference between mill finish and black?
Mill finish is bare satin aluminum with no coating, so there is nothing to chip or flake. Black is powder coat over the same aluminum. Where both are offered, they appear as a Finish option on the product.
Will a truck rack work with a canopy?
Yes, with the over-canopy rack rather than the box-mounted rear rack. Full size and compact versions are listed with their own install kits.
