Washington UT's 4x4 & 4WD Specialists
Lift kits. Suspension. Drivetrain. Alignment. If it's built to go off-road, we know how to work on it.
MST Motorsports is Washington UT's dedicated 4x4 and 4WD specialist — the shop Southern Utah truck, Jeep, and Bronco owners trust when the build has to perform on the trail and drive right on the road.
What We Handle
Lift Kit Installation
Full suspension lifts, leveling kits, and body lifts. Every major brand. Every height. Geometry correction included so your 4x4 drives right after it sits taller.
4WD Drivetrain Service
Transfer cases, front and rear differentials, locking differentials, and axle shafts. Built for the stress Southern Utah terrain puts on 4x4 drivetrains.
Suspension & Steering
Control arms, ball joints, tie rods, track bars, drag links, and bushings. Stock to full custom builds — we handle the full spectrum of 4x4 undercarriage work.
Post-Lift Alignment
Hunter Hawkeye Elite precision alignment after every lift. Caster, camber, and toe dialed to spec for your actual ride height. Before/after printout standard.
Skid Plate & Protection
Underbody protection installed right — rock sliders, skid plates, and differential covers for the rocks, sand, and desert terrain around Sand Hollow and beyond.
Pre-Trip Inspection
Full drivetrain, suspension, and steering inspection before Sand Hollow, Moab, or any serious run. Catch problems before you're miles from pavement.

What Changes When You Lift It
Lifted Geometry Changes Everything
Caster, pinion angle, and CV angle all need correction after a lift. Once geometry moves past the factory adjustment range, parts start wearing out fast — so we measure it and correct it rather than assume it still fits.
Drivetrain Stress Is Real
Lockers, larger tires, and more torque put stress on axles and transfer cases that stock-spec repairs don't account for. We build and repair drivetrains for the loads they'll actually see off-road.
Terrain-Specific Setup
A build for Sand Hollow sand is different from a build for Hurricane Cliffs rocks. We set up suspension, alignment, and drivetrain for the terrain you actually drive — because Southern Utah has more than one kind of trail.
4WD and Four-Wheel Drive Systems We Service
4x4, 4WD and four-wheel drive describe the same hardware, and the work is the same whichever name is on the badge. Part-time systems with a manual transfer case, electronic shift-on-the-fly systems, full-time and automatic 4WD, and all-wheel drive crossovers all come through the shop.

- Drivetrain vibration diagnosis after a lift, tire size change or gear swap
4x4 Suspension and Off-Road Alignment
Off-Road Alignment
An off-road truck is aligned at its actual ride height with the tires and wheels it runs on. Lift changes caster and thrust angle, oversized tires change scrub radius, and a stock alignment spec no longer matches the geometry. We measure on the Hunter Hawkeye Elite rack, set caster and toe for the build, and hand over a before-and-after printout. Details on the lifted truck alignment page.
4x4 Suspension Work
Coilovers, leaf packs, long-travel and bypass shocks, control arms, track bars, sway bar disconnects and steering stabilizers. Shocks are rebuilt and re-valved in-house on the shock bench, so valving can be matched to the terrain the vehicle actually runs. Truck, Jeep and SUV suspension work is covered on the truck suspension and Jeep suspension pages.
Cooling for Desert Use
Crawling in July is the hardest thing you can ask of a cooling system: maximum engine load, minimum airflow. Towing to the trailhead and then working the vehicle hard in the heat compounds it.
We service and repair radiators, cooling fans and fan clutches, thermostats, water pumps, hoses, and coolant on trucks, Jeeps, Broncos, and SUVs. Tell us how the vehicle is used — towing, heavy build, big tires — and we will evaluate the system against that duty cycle rather than a commuter assumption.
Trail-Readiness Inspections
Before a weekend at Sand Hollow, a run through Hurricane Cliffs, or a trip out past Virgin and Leeds, we go through the vehicle end to end: front-end play, ball joints and bushings, steering components, shock condition and mounting hardware, brakes, driveline angles and u-joints, tire condition and pressures, fluids, and cooling.
You get the findings as a digital inspection with photos sent to your phone, and you decide what to address. Book ahead and there is room to fix anything we find before you load the trailer.
Maintenance for Modified Vehicles
A lifted rig on oversized tires is not a stock vehicle with taller springs. Wear patterns change, steering and driveline components carry more load, brakes work harder, and the inspection priorities shift. We maintain modified 4x4s as normal work — oil and fluids, brakes, cooling, diagnostics — with the inspection focus set for how the vehicle is actually built.
Lift and leveling kits, coilovers, springs, upper control arms, track bars, and shock packages are installed with brake line clearance, bump stop setup, driveline angles, and hardware torque treated as part of the work. Shocks are rebuilt in house — Fox, King, Elka, and Walker Evans — disassembled, cleaned, re-sealed, re-valved when requested, and nitrogen-charged on site.
Qualifying auto repairs are backed by our 36-month / 36,000-mile workmanship warranty on parts and labor. Full detail on maintenance for lifted and modified vehicles, and package options on lift kit installation. We are open Mon–Fri: 8:00am – 5:00pm with shuttle service, after-hours drop-off and pickup, two-way texting, and online booking 24/7. Financing is available through Acima, Affirm, Klarna, and Sunbit.

Frequently Asked Questions
What is a 4x4 specialist vs a regular mechanic?
A 4x4 specialist understands lifted geometry, drivetrain stress from larger tires and lockers, off-road terrain demands, and the interaction between suspension, alignment, and drivetrain. On a lifted vehicle, geometry correction, pinion angle, and CV joint angles all have to be measured and set. Getting them right is the difference between a lift that lasts and one that eats parts.
Do you service stock (non-lifted) 4WD vehicles?
Yes. Transfer cases, differentials, front axle service, and alignment on stock 4WD trucks and Jeeps are all part of our regular service menu. You don't need a lift kit to get dealer-quality 4x4 service at MST.
How often should a lifted 4x4 be realigned?
After any suspension change, tire size change, or if you notice uneven wear, pulling, or a wandering steering feel. At minimum, we recommend an alignment check annually if you're regularly off-road — impacts and terrain shift angles faster than highway driving.
Do you work on diesel 4x4 trucks?
Yes — Ford Power Stroke, Ram Cummins, and Chevy/GMC Duramax all come through the shop for drivetrain, suspension, and alignment work. Heavy diesel 4x4s place even more stress on axles and suspension components, so proper setup matters even more.
Do you only work on Jeeps and Broncos, or on other 4x4s too?
All of them. Off-road capability is not one brand. We build, align, and maintain 4x4s of every kind — Jeep, Bronco, lifted trucks, and off-road SUVs including 4Runner, Land Cruiser, Grand Cherokee, and more. Half-ton and three-quarter-ton pickups running 35s and 37s are just as much a part of the daily work here as solid-axle Wranglers.
What is Road Force balancing and why does it matter on off-road tires?
A standard spin balance only corrects weight distribution. Road Force balancing applies a loaded roller against the tire to simulate the road. It reveals stiffness variation in the tire and how the tire and wheel are matched to each other. Heavy, aggressive off-road tires vary more than street tires do, so this is where most highway vibration complaints on 35s and 37s actually get solved.
Do you rebuild shocks in house?
Yes. Fox, King, Elka, and Walker Evans shocks are disassembled, cleaned, re-sealed, re-valved when requested, and nitrogen-charged on site. That work happens on our own bench in Washington.
Will modifications void the maintenance work you do?
No. We maintain lifted and modified vehicles as normal work, and qualifying auto repairs are backed by our 36-month / 36,000-mile workmanship warranty on parts and labor. What changes on a modified rig is the inspection focus. Driveline angles, u-joints, steering component wear, ball joints, brake capacity relative to tire size, and cooling under load all deserve more attention than on a stock vehicle.
What should I have checked before a weekend at Sand Hollow?
A trail-readiness inspection covers front-end play, ball joints and bushings, and steering components. It also checks shock condition and mounting hardware, brakes, driveline angles and u-joints, tire condition and pressures, fluids, and cooling. You get the findings as a photo-documented digital inspection and decide what to address.
Does desert heat require anything different from a 4x4 cooling system?
It requires the system to be in good condition, because low-speed trail work in summer means high engine load with very little airflow through the radiator. We service and repair radiators, fans and fan clutches, thermostats, water pumps, hoses, and coolant. If you tow or run a heavy build, mention it and we will evaluate the system for that duty cycle.
