Truck Suspension Repair & Service
Leaf Spring, Coilover, Control Arm & Complete Suspension System Service for All Truck Platforms
MST Motorsports provides professional truck suspension repair and service in Washington, Utah, serving St George and Southern Utah. Our factory-trained, certified technicians bring more than 80 years of combined experience, and qualifying automotive repairs are backed by our 36-month/36,000-mile nationwide warranty on parts and labor.
Southern Utah heat, rough roads, construction sites and off-road terrain load every suspension component on a half-ton daily driver or a heavy-duty work truck. Our technicians diagnose and repair suspension issues across Ford, Chevrolet, GMC, Ram, Toyota and Nissan truck platforms, from stock configurations to heavily modified builds.
Leaf Spring & Spring Pack Service
Leaf springs support payload capacity and hold ride height under load on most truck rear suspensions, and they fatigue, sag or crack over time. Trucks that carry heavy loads or tow trailers across Southern Utah grades see it soonest.
We inspect leaf spring packs for sagging, cracked leaves, broken center bolts, worn bushings and U-bolt condition, and install OEM or aftermarket leaf springs when replacement is needed. Ride height, axle alignment and load capacity are verified after installation, and add-a-leaf kits and helper springs are available for trucks that need more capacity.
Coilover, Strut & Shock Service
Coilover struts and coil-spring-over-shock assemblies on the front of most modern trucks control ride quality, handling and nose dive under braking. Desert heat accelerates seal wear and fluid degradation in shock absorbers and struts.
We service OEM and aftermarket coilover systems from Fox, King, Bilstein and Icon, including leak inspection, bushing replacement, spring rate changes, preload adjustment and complete assembly replacement. On aftermarket coilover conversions we match valving and spring rates to how the truck is driven.
Control Arms, Bushings & Ball Joints
Control arms connect the suspension to the frame and control wheel movement through travel, and the bushings and ball joints at each end are wear items. As they degrade they produce clunking noises, loose steering and poor alignment retention.
We install OEM replacement arms and aftermarket upper control arms (UCAs) built for lifted applications, which restores the suspension geometry that factory arms leave behind at a taller ride height. Alignment and steering geometry are verified after any control arm service.
Lifted Truck Suspension Specialist
MST Motorsports installs and services lifted truck suspension in Washington, Utah, from a fresh lift kit to component upgrades on a truck that is already lifted. Lifting a truck changes alignment angles, CV joint operating angles, steering geometry and driveline angles, and each of those is measured and corrected as part of the work.
Our technicians verify alignment, ride height, driveline angles and steering geometry after every lift-related service. That is what keeps tire wear even and handling predictable on Southern Utah highways and trails.
Frequently Asked Questions
How do I know if my truck needs suspension repair?
Common signs are a rough or bouncy ride, nose dive under braking, uneven tire wear, clunking over bumps, or the truck sitting lower on one side. If the truck handles differently than normal, especially after hauling heavy loads or off-road use, have the suspension inspected.
How often should truck suspension components be inspected?
For trucks used in Southern Utah conditions, we recommend suspension inspection every 30,000–50,000 miles or annually. Trucks used for towing, hauling, or off-road driving should be inspected more frequently. Desert heat accelerates bushing and shock wear.
Can you work on lifted trucks?
Yes. MST Motorsports specializes in lifted truck suspension service. We install lift kits, repair and upgrade suspension components on already-lifted trucks, and provide proper alignment after any lift modification. Visit our lifted truck alignment page for more details.
Do you service both leaf spring and coilover suspension systems?
Yes. We service all truck suspension configurations including leaf spring rear suspensions, coilover front suspensions, torsion bar systems, and aftermarket coilover conversions. Our technicians are experienced with both OEM and aftermarket suspension platforms.
What truck brands do you service?
We service all major truck brands including Ford (F-150, F-250, F-350), Chevrolet/GMC (Silverado, Sierra), Ram (1500, 2500, 3500), Toyota (Tacoma, Tundra), and Nissan (Titan, Frontier). We work with both stock and modified suspension systems.
Do you rebuild shocks in-house or send them out?
In-house. Fox, King, Elka, and Walker Evans shocks are disassembled, cleaned, re-sealed, re-valved when requested, and nitrogen-charged on-site. Our Washington, UT shop is about 7 minutes east of downtown St George.
How long does suspension work usually take?
Timing depends on the work involved. A shock replacement is a smaller job than a full lift kit with alignment, and diagnostic work depends on what the inspection finds. Call (435) 256-8899 and we will go over what your truck needs.
