Gas Caps and Filler Assemblies

The fuel system on your Jeep, truck or SUV is one of its most important. If you 4X4 does not have a steady supply of high-quality fuel, you can't expect it to deliver a dominant performance when you hit the trail, track or highway. Still, as your vehicle ages, fuel components can wear out, break or go missing. Here at 4WheelParts.com, we have locking gas caps, filler assemblies, performance parts and other vital components. Instead of limiting your rig's driving capabilities, let us help you take your off-road experience to the next level.

Replacement Gas Caps and Modern Filler Assemblies
Your 4X4's fuel system performs optimally when it stays closed. While you must remove your vehicle's gas gap to add fuel, you must have a tight cap to avoid sputtering and stalling. If your rig's cap has seen better days or if it is missing entirely, we have you covered. Our selection of replacement gas caps includes both OEM caps and modern vented caps to help you meet your off-road goals. When ordering from our inventory of gas caps and filler assemblies for trucks, Jeeps and other 4X4s, you choose from brands you already know and trust, such as Omix-ADA and Crown Automotive.

Innovative Performance Parts
While some motorists accept a drop in performance, you simply can't. If your rig isn't running quite right, we have the performance parts for sale you need to boost performance and increase power. Opt for exhaust system upgrades, air intake modifications and other power-enhancing components to get the most out of your machine.
