TRUCK SUSPENSION REPAIR & SERVICE
Leaf Spring, Coilover, Control Arm & Complete Suspension System Service for All Truck Platforms
MST Motorsports provides comprehensive truck suspension repair and service in St George, Washington, and throughout Southern Utah. Your truck's suspension system absorbs road impacts, maintains tire contact, controls body roll, and supports the loads you carry — making it one of the most critical systems on your vehicle.
Whether you drive a half-ton daily driver or a heavy-duty work truck, the demanding conditions of Southern Utah — heat, rough roads, construction sites, and off-road terrain — put significant stress on every suspension component. Our technicians diagnose and repair suspension issues across all major truck platforms, from stock configurations to heavily modified builds.
Leaf Spring &Spring Pack Service
Leaf springs are the backbone of most truck rear suspension systems, supporting payload capacity and maintaining ride height under load. Over time, leaf springs fatigue, sag, crack, or break — especially on trucks that regularly carry heavy loads or tow trailers across Southern Utah's terrain.
We inspect leaf spring packs for sagging, cracked leaves, broken center bolts, worn bushings, and U-bolt condition. When replacement is needed, we install quality OEM or aftermarket leaf springs and verify proper ride height, axle alignment, and load capacity after installation. For trucks that need additional capacity, we offer add-a-leaf kits and helper spring solutions.
Coilover, Strut &Shock Service
The front suspension on most modern trucks uses coilover struts or coil-spring-over-shock configurations that combine spring support with damping in a single assembly. These components control ride quality, handling, and nose dive during braking. Desert heat accelerates seal wear and fluid degradation in shock absorbers and struts.
We service both OEM and aftermarket coilover systems from manufacturers like Fox, King, Bilstein, and Icon. Services include leak inspection, bushing replacement, spring rate changes, preload adjustment, and complete assembly replacement. For trucks with aftermarket coilover conversions, we ensure proper valving and spring rates match your driving conditions.
Control Arms,Bushings & Ball Joints
Control arms connect your truck's suspension to the frame and control wheel movement during travel. The bushings and ball joints at each end of the control arm are wear items that degrade over time, causing clunking noises, loose steering, and poor alignment retention.
On lifted trucks, factory control arms often create geometry problems that accelerate ball joint and CV joint wear. We install both OEM replacement arms and aftermarket upper control arms (UCAs) designed for lifted applications that restore proper suspension geometry. After any control arm service, we verify alignment and steering geometry to ensure safe, predictable handling.
Lifted TruckSuspension Specialist
MST Motorsports is Southern Utah's specialist for lifted truck suspension work. Lifting a truck changes the entire suspension geometry — affecting alignment angles, CV joint operating angles, steering geometry, and driveline angles. Improper lift installations are one of the most common causes of premature component wear we see in the shop.
Whether you're installing a new lift kit, troubleshooting problems with an existing lift, or upgrading components on a lifted truck, our technicians understand the engineering behind proper lift installations. We verify alignment, ride height, driveline angles, and steering geometry after every lift-related service to prevent premature wear and ensure safe handling.
Frequently AskedQuestions
How do I know if my truck needs suspension repair?
Common signs include a rough or bouncy ride, nose diving during braking, uneven tire wear, clunking or squeaking noises over bumps, the truck sitting lower on one side, or visible damage to suspension components. If your 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 at our Washington, UT shop — about 7 minutes east of downtown St George. No shipping delays, no third-party markups.
How long does suspension work usually take?
A simple shock replacement is often same-day. A full lift kit with alignment is typically 1-2 days. Diagnostic work depends on what we find. We give honest time estimates up front and call before doing any extra work.
