Running Boards, Side Steps & Fender Flares in Sun City, AZ
Make a taller truck easy to climb into and give it a finished look — running boards, nerf bars, power steps, rock sliders, and fender flares, installed to fit.
A lifted or full-size truck looks great, but getting in and out — especially for kids, shorter drivers, or anyone with a bad knee — can be a chore. Running boards, side steps, and nerf bars fix that with a solid place to step, and power steps take it further by deploying automatically when you open the door and tucking away when you drive. It's one of the upgrades families notice and appreciate every single day.
Steps aren't only about access. Rock sliders add real rocker-panel protection for trail use, and fender flares give you coverage for larger tires while cleaning up the look of a lifted truck. Whatever you choose, correct fitment and secure mounting are what separate an upgrade that looks factory from one that rattles and sags. We mount everything to spec so it's solid and clean.
Tell us your truck and what matters most — easy access, protection, or a finished look — and we'll recommend the right steps and flares and quote them out the door, parts and installation included.

FAQ
What's the difference between running boards, nerf bars, and power steps?
Running boards are a full-length flat step, nerf bars are round tube steps with a stepping pad, and power steps are motorized boards that drop down when you open the door and retract when you drive. Power steps give the easiest access and the cleanest look; we'll help you pick based on your budget and needs.
Do power steps work in the long run?
Good-quality power steps are built for daily use and weather, and correct installation and wiring are what keep them reliable — which is exactly what we do. We'll set them up so they deploy smoothly for years.
Do I need fender flares after a lift or bigger tires?
Often, yes — larger or wider tires can extend past your fenders, and flares provide the coverage that keeps you legal and protects your paint from rock chips and debris. We'll check your fitment and recommend what you need.
How much does step or flare installation cost?
It depends on the product and your vehicle, but you'll get one out-the-door price covering parts and installation before we begin. Tell us your truck and what you want and we'll quote it.
