    MST Motorsports provides auto repair and maintenance for trucks, Jeeps, Broncos, SUVs, and other off-road-capable vehicles. While our shop is known for suspension work, shock rebuilds, and powersports service, we also handle the full range of automotive repair and maintenance that keeps daily drivers reliable — engine diagnostics, brake service, cooling system repair, steering repair, fluid services, and preventative maintenance.

    The people doing that work are ASE-certified technicians — including ASE Master certification on staff — factory-trained through Jeep, Dodge, Ram, Polaris, and Can-Am programs. The same techs who build and modify vehicles here are the ones handling your maintenance, so you get dealer-level training in a family-owned shop that has served Southern Utah since 2004.

    Our focus is trucks, SUVs, and vehicles that see real use — highway driving, towing, off-road recreation, and the heat and dust of Southern Utah. Every repair gets the same thoroughness whether it's a routine oil change or a complex drivability diagnosis: proper diagnostics, quality parts, and a documented result. The shop is equipped for it — OEM factory-level scan tools on the automotive side, Hunter Hawkeye Elite alignment, and a Hunter Road Force balancer for vibration a standard spin balance can't solve. Most maintenance is done same-day or next-day.

    The same shop that maintains your daily driver also builds and services lifted trucks, Jeeps, Broncos, and UTVs — from leveling kits and suspension geometry to shock rebuilds and Hunter Hawkeye Elite alignment. Whether your vehicle is stock or modified, MST covers it from bumper to bumper.

    Engine Diagnostics & Repair

    Check engine lights, rough idle, reduced power, misfires, and unusual noises all start with proper diagnostics. We use professional scan tools to read fault codes, live data, and freeze frame information — but codes are just the starting point. We verify the actual fault with circuit testing, pressure testing, and visual inspection before recommending any repairs.

    We service gas and diesel engines across all the major truck and SUV platforms — Ford EcoBoost and Power Stroke, Chevy LS and Duramax, Ram Hemi and Cummins, and Toyota engines. Whether it's a turbo issue on a Raptor, a fuel system concern on a Duramax, or a drivability problem on a daily-driven Tacoma, we diagnose it correctly and repair it right.

    Brake Repair & Service

    Brakes are a safety system, and we treat them that way. We perform complete brake diagnostics and service including pad and rotor replacement, caliper service, brake fluid flush, brake line inspection, and parking brake adjustment. For trucks that tow, we pay special attention to brake capacity and heat management — towing loads through Southern Utah's terrain puts significant demand on the brake system.

    Off-road vehicles need brake attention too. Sand, dust, and water intrusion contaminate caliper slides and degrade pad material. If your brakes feel spongy, noisy, or less effective than they used to be, don't wait — bring it in for an inspection.

    Cooling System Diagnostics & Repair

    Southern Utah summers push cooling systems hard. Sustained desert heat combined with towing, slow-speed off-road crawling, or heavy sand riding can overwhelm a cooling system that isn't maintained properly. We see overheating issues on trucks, Jeeps, and Broncos regularly during the summer months — often caused by a combination of low coolant, degraded hoses, failing thermostats, or clogged radiators.

    We perform complete cooling system diagnostics and service including pressure testing, thermostat replacement, radiator inspection and flush, hose replacement, water pump service, and coolant flush and fill. For vehicles that tow or see sustained off-road use, proactive cooling system maintenance is one of the most important things you can do to prevent expensive engine damage.

    Vehicles We Commonly Service

    Our auto repair and maintenance services cover the truck, SUV, and off-road vehicle platforms commonly used in Southern Utah. That includes Ford F-150, Ranger, Raptor, Super Duty, Explorer, and Expedition; Chevy Silverado, Colorado, Tahoe, and Suburban; GMC Sierra and Canyon; Ram 1500, 2500, and 3500; Toyota Tacoma, Tundra, and 4Runner; Lexus GX and LX; Nissan Frontier and Titan; Jeep Wrangler, Gladiator, Grand Cherokee, and Cherokee; and Ford Bronco.

    Our focus is the vehicles that define Southern Utah driving: trucks that tow, Jeeps and Broncos built for the trail, SUVs that handle family duty and weekend adventures, and the UTVs and side-by-sides that share the same driveways.

    Honda, Subaru, Nissan & Toyota Cars & SUVs

    While trucks, Jeeps, and Broncos are our core, MST also services the domestic and Asian passenger vehicles common in Southern Utah — Honda, Subaru, Nissan, and Toyota cars and SUVs for maintenance, brake service, alignment, cooling, and engine diagnostics. Civic, Accord, CR-V, Pilot, Outback, Forester, Ascent, Rogue, Pathfinder, Camry, Corolla, RAV4, and Highlander all get the same honest diagnostics and quality workmanship we apply to the truck fleet.
