MST Motorsports is a professional, independent alternative to the dealer in Washington, Utah, for factory-scheduled maintenance and repair on Ford, Chevrolet, GMC, Ram, Jeep, Toyota, Honda and Nissan cars, trucks and SUVs, stock or modified. Our factory-trained, certified technicians use OEM factory-level scan tools, OE or OE-equivalent parts and the manufacturer's service intervals on everything from a commuter sedan to a lifted Jeep or Bronco. Every visit is documented with a digital inspection sent to your phone with photos and video. Southern Utah heat, dust and towing grades shorten some factory intervals, and we apply the severe-duty schedule where your driving calls for it. Qualifying automotive repairs are backed by our 36-month/36,000-mile nationwide warranty.

Manufacturer Recommended Maintenance Schedules
Manufacturer maintenance schedules are the baseline for keeping a vehicle reliable and a factory warranty intact, and MST Motorsports services the platforms listed below to those schedules. In Southern Utah's heat, dust and terrain some intervals tighten, and each service is documented with photos and notes sent to your phone.
Ford Super Duty (F-250 / F-350)
Power Stroke diesel and gas — full schedule with towing adjustments.
Jeep Wrangler (JK / JL)
Stock or lifted, Dana axle service and off-road post-trip checklist.

EcoBoost engines, HOSS suspension, and BorgWarner 4WD service.
Ram 2500 / 3500 Cummins

Why Southern Utah Modifies Factory Schedules
Heat
Triple-digit summer heat accelerates oil breakdown, hardens rubber, and stresses cooling systems well past factory normal-duty assumptions.
Load & Towing
Southern Utah grades, tow loads, and desert speeds shorten transmission fluid, brake fluid, and driveline fluid life.
Dust & Debris
Sand Hollow, desert roads, and worksite dust call for shorter air filter intervals than the factory book assumes.
Jeep Platforms & Off-Road Damage Repair
Jeep service for Hurricane, St. George and Washington owners covers Wrangler JL (2018+) and JK, Gladiator JT, and Cherokee and Grand Cherokee L, across the 3.6L Pentastar, 2.0L turbo, 3.0L EcoDiesel and 6.4L Hemi 392 engines. Factory-stock Pentastar oil service and a full front-end rebuild on a six-inch-lifted JL running 40-inch tires are both within scope.
Modified Wranglers are welcome, including lifted JL and JK builds on coilovers, long-arm kits, aftermarket steering, one-ton axles and 37-inch tires and up, and each is aligned, serviced and diagnosed as built.
Off-road damage repair is included, and bent tie rods, damaged track bars, torn CV boots, sheared skid plate hardware and broken sway bar disconnects are common after a hard weekend at Sand Hollow. Clear written estimates are provided for off-road damage repair.

Frequently Asked Questions
Does going to MST void my warranty?
No. The Magnuson-Moss Warranty Act protects your right to have maintenance and repairs performed at an independent shop without voiding your factory warranty. We use OE or OE-equivalent parts and document every service with photos and notes sent to your phone, which are the records a manufacturer requires to honor a warranty claim.
Can you service my vehicle under warranty?
Yes. The Magnuson-Moss Warranty Act protects your right to have maintenance and repair performed at an independent shop, and we document every service with photos and part numbers. Third-party extended warranties and vehicle service contracts are also accepted; we diagnose the vehicle, document the findings and submit the claim to your provider for approval.
Are your parts the same quality as dealer parts?
Yes, and often the same parts. We source OE parts, OE-equivalent parts from the same suppliers that serve dealer parts departments, and premium aftermarket components such as upgraded brake pads and heavy-duty suspension parts where they add durability.
Does following manufacturer maintenance protect my warranty?
Yes. Documented records of scheduled maintenance, which we provide with every service, keep your factory warranty intact. The Magnuson-Moss Warranty Act protects your right to have that maintenance performed at a qualified independent shop, and we document parts, fluids and inspection findings on every service.
How is MST's maintenance schedule different from the dealer's?
We follow the manufacturer's schedule as the baseline, which is the requirement for warranty protection. Intervals are then adjusted for Southern Utah operating conditions where warranted, such as dust-loaded air filters, heat-affected fluids and tow-heavy transmissions, typically by applying the severe-duty schedule to how you use the vehicle.
What if my vehicle isn't listed?
We service more vehicles than we have built dedicated pages for. Call or text (435) 256-8899 or use our contact form, and we will confirm the schedule that applies to your vehicle and book your appointment.
