FiberwerX 2014–2021 Toyota Tundra Bedsides

FiberwerX Bedsides provide the massive 4" bulge and 2" vertical rise required to let your rear tires travel freely without damaging your bodywork. Designed to mimic the aggressive styling of modern desert racers, these bedsides transition seamlessly from the Tundra's cab to the rear tailgate, giving your truck a cohesive, wide-track stance that is as functional as it is intimidating.

Choose Your Material

• Hand-Laid Fiberglass: The heavy-duty industry standard. These arrive in a white gelcoat finish, ready for professional prep and paint to match your factory color.
• Carbon Fiber Composite: The pinnacle of performance. For those wanting maximum strength and a high-tech race aesthetic, our carbon fiber composite option offers an incredible strength-to-weight ratio.

Fuel Door Customization

• To suit your specific build goals, these bedsides are available in two configurations:
  • With Fuel Door Pocket: Features a recessed pocket designed to accept your factory fuel door housing. This is the preferred choice for overland and daily-driven rigs that utilize the stock fuel tank.
  • Without Fuel Door (Clean Look): A smooth, continuous bedside without the cutout. This is the go-to for dedicated race builds or Pre-runners utilizing a bed-mounted fuel cell.

Key Features

• 4" Bulge & 2" Rise: Perfectly matched to complement Fiberwerx front fenders, providing massive clearance for 37" tires at full compression.
• Retains Factory Utility: Engineered to work with your OEM 2014–2021 tail lights and tailgate, maintaining the truck's daily functionality.
• Lightweight Durability: Significantly lighter than the factory steel skins, reducing unsprung feel and helping to keep the truck nimble on high-speed washboard roads.
• Specifically molded for the Tundra's 5.5' Short Bed.

Pro Tip: When swapping to fiberglass bedsides on a Tundra, the structural support of the factory steel skin is removed. We highly recommend installing a set of Bed Stiffeners at the tailgate. This reinforces the rear of the bed, which is especially important if you plan on mounting a bed rack, a full-size spare tire, or a rooftop tent.
