AMP-Research Parts & Accessories

Being able to go wherever you want is most of the fun of owning a 4X4. Still, many Jeep and truck owners get a kick out of fully customizing their rigs. Whether you need extra bed space or help getting into the cab, 4 Wheel Parts has you covered. Our inventory includes the aftermarket accessories you want to enjoy your vehicle.

Extend Your Truck's Tailgate
Whether you use your rig as a work truck or pack it for extreme off-road adventures, you may need additional bed space. With a truck bed tailgate extension, you increase your truck's storage capacity. Since extenders attach and remove easily, you can be sure your truck is ready to haul anything you need.

Climb on Board
Your rig is a monster. To help you climb on board, install a pair of running boards. If you need additional assistance, choose a running board extension arm for the boost you and your passengers need. Likewise, since your truck is tall, you may have difficulty loading and unloading the bed. Receiver-mounted steps allow you easy access to the space behind your rig's cab.

Choose Top-Quality Accessories
As a serious 4X4 enthusiast, you want your Jeep or truck to look and run its best. When you replace engine or body parts, you always demand OEM-quality components. That same standard applies when you order aftermarket accessories. If you don't demand top-quality parts, you can't be certain your rig is ready for conquering the trail. When you order from 4 Wheel Parts, you never have to worry about quality. Since we source our inventory from over 600 top brands, you can be certain you are getting the best accessories when you order from us.

Here at 4 Wheel Parts, we are proud to be your 4X4 parts and accessories partner. With our 100% price match guarantee, you know you aren't paying a premium for the parts you need to customize your rig. Instead, if you find a better price somewhere else, we'll gladly match it. With our huge selection of AMP-Research parts, we are confident we have the aftermarket accessories you need to get more out of your machine. Browse our inventory and place your order now.

Tustin, California-based AMP Research got its start in 1980 and was acquired by Lund International just a few years ago. The company's motto 'Innovation in Motion' applies to its pioneering 4x4 products ranging from PowerStep running boards to BedStep truck bed access steps to fuel doors. AMP's patented PowerStep is a retractable, power-deployed running board that makes it convenient for jeepers on the trail to enter and exit their vehicles and alloy fuel-filler doors for Wranglers are cam-action hinged to eliminate rattling and feature superior styling. Add flair to your rig, with AMP's safe, reliable accessories that are easily installed and durable for off-road environments.
