Best TRX Exterior Accessories to Buy

Exterior accessories are where a TRX goes from stock truck to your truck. The best ones add real utility — protection, easier access, cargo security — on top of the looks. This roundup covers the categories worth your money and points you to both new parts on Amazon and used/OEM options on eBay Motors.

Tonneau covers

A tonneau cover is one of the highest-value additions: it protects cargo from weather and theft, cleans up the truck’s profile, and can even help highway fuel economy a touch. Soft roll-up covers win on price and simplicity; hard folding and retractable covers win on security and weather sealing. For the full breakdown of cover types and the 5’7” bed fitment details, see our dedicated TRX tonneau cover buyer’s guide; or browse the exterior category for options.

Step bars and running boards

The TRX sits tall on its off-road suspension and 35” tires, so the cab can be a real climb. Step bars and running boards make daily entry easier, while rock rails add rocker protection for the trail. Confirm fitment for the TRX and your model year.

Fender flares

Flares cover wider tires, protect the body from rock chips and mud, and give the truck a more aggressive stance. Pocket-style and bolt-on looks are popular; pick the style that matches your build.

Grilles and front-end styling

A new grille is the fastest way to change the face of your TRX. Beyond looks, some designs improve airflow. Match the design to your model year for a clean fit.

Frequently Asked Questions

Are hard or soft tonneau covers better?

Soft roll-up covers are lighter, cheaper, and easy to remove for full bed access. Hard folding or retractable covers offer better security, weather sealing, and a more premium look at a higher price. Choose based on how much you value security versus cost and simplicity.

Do step bars and running boards fit the TRX?

The Ram 1500 TRX is offered only as a crew cab, so fitment is more consistent than on trucks with multiple cab styles — but you still need to confirm the part is listed for the TRX and your model year, since bar length and mounting points can differ from a standard Ram 1500. Rock rails are a popular alternative that adds off-road rocker protection.
