UTV Accessory Installation in Washington, Utah
Winch mounting and wiring, lighting, cab accessories, armor, radios and seats — installed and wired at our shop in Washington County.
MST Motorsports installs and wires UTV accessories at our shop at 987 S 1900 East in Washington, Utah — minutes from St. George, Hurricane, Ivins, Santa Clara, La Verkin, Leeds and Sand Hollow State Park. Our factory-trained, certified technicians handle fitment, mounting, wiring and setup on Polaris, Can-Am and Kawasaki platforms. You bring the part, or tell us what you are after and we will source it, and it is installed and wired here.
Accessory work on a side-by-side is its own discipline. There is less room for a wire run, the frame is exposed to sand and water in a way a unibody never is, and weight added at the front changes how the machine steers. Mounting hardware, cable routing, fusing and ground quality are what make an accessory last a season at the dunes.
UTV Winch Mounting & Wiring in Washington County
UTV winch mounting and wiring is mostly electrical work, and none of it is visible once the plastics go back on. The mount plate has to match both the winch pattern and the machine's frame or bumper, and it has to sit where the fairlead can pull at an angle without the rope contacting bodywork.
The contactor is located clear of standing water and packed sand. Power and ground cables are sized for the winch's draw, routed away from exhaust heat and suspension travel, secured against chafing on a frame edge, and protected at the battery. Grounds go to clean metal, and the control — dash rocker, handlebar-style switch or handheld — is run and mounted within reach.
Sand Hollow and Warner Valley recoveries are hard on a winch, and one that draws weakly, trips or works intermittently usually has a connection or ground problem rather than a failed motor. That work belongs with UTV electrical diagnostics rather than a replacement winch.

Lighting, Wiring and Switch Control
UTV lighting installations fail at the wiring far more often than at the light itself. A light bar fed through an undersized wire, or off a circuit that was never meant to carry it, will dim, flicker or blow a fuse. We wire lighting through relays with the fusing at the power source, route the harness clear of heat and suspension movement, and mount the switch where it is easy to reach.
Rock lights sit in the most exposed place on the machine for water and debris, and chase lights ride a whip that flexes constantly, so both get connectors and strain relief selected for that duty. The same approach applies on the truck and Jeep side — see lighting and accessory installation for that work.
Roofs, Doors, Bumpers and Armor
Cab accessories bolt on cleanly to a cage that has never been touched. On a machine that has been repaired, re-caged or lightly bent, a roof or door that will not line up is usually telling you something about the cage rather than about the part. We check the cage before forcing a panel.
Bumpers, rock sliders and skid plates mount to the frame and carry real load, so hardware grade, thread engagement and torque matter. We check that a front bumper and winch combination still clears the suspension through full travel, and that a skid plate is not trapping sand against a component that needs airflow.
What Accessories Do to a Southern Utah Machine
A roof, full doors, a steel front bumper and a winch add mass high and forward, which is not where the factory suspension tune expected it. In deep sand that reads as a machine that pushes in a turn, and on slickrock as bottoming that was not there before. A full round of accessories is worth pairing with UTV suspension service or a shock re-valve so the setup matches the new weight.
Bigger tires are the other change that travels with an accessory build. Tire and wheel work is covered on UTV tires and wheels, and if the tires go up far enough to hurt low-speed drive, that is where gear reduction and portal boxes come in. Everything else we do for side-by-sides is on the UTV service hub.
