UTV SHOCK REBUILD SERVICE

In-House Shock Rebuild, Re-Valve & Service for Fox, King, Elka & Walker Evans

MST Motorsports provides in-house UTV shock rebuild service in St George, Washington, and across Southern Utah — see our dedicated St George shock rebuild page for directions and turnaround. We rebuild Fox, King, Elka, and Walker Evans shocks — the major brands found on Polaris RZR, Can-Am Maverick, Kawasaki KRX, and other powersports platforms. Our shop handles the complete process in-house, from disassembly to reassembly, without shipping your shocks out and waiting weeks for service. Rebuilds, re-valving, and the suspension setup that follows — done in-house by our own techs, not farmed out to another shop.

Shocks are the most critical component of your UTV's suspension system. They control how your machine responds to every bump, rock, dip, and landing. When shock oil breaks down, seals wear, or internal components degrade, your ride quality suffers, handling becomes unpredictable, and the risk of component damage increases. In Southern Utah's desert conditions — especially at Sand Hollow — shock degradation happens faster than most riders realize.

What a difference.

Complete ShockRebuild Process

Our in-house shock rebuild process includes:

Disassembly & Inspection — Complete disassembly with inspection of shaft condition, body bore, and all internal components
Seal & Bearing Replacement — Fresh seals, bushings, and bearings to restore leak-free operation
Internal Component Evaluation — Assessment of piston, shim stacks, and valving components for wear or damage
Oil Replacement — Fresh shock oil at the proper viscosity for your application and conditions
Bladder/IFP Inspection — Inspection and replacement of internal floating pistons and bladders as needed
Reassembly & Nitrogen Charge — Precision reassembly with proper nitrogen pressure for gas-charged shocks
Testing — Stroke testing to verify consistent, leak-free operation

Shock Re-Valve &Custom Tuning

Re-valving changes the internal shim stacks that control how fluid flows through the shock — adjusting compression and rebound damping characteristics to match your specific riding conditions, vehicle weight, and performance goals.

Factory shock valving is designed for average conditions and average riders. If you ride primarily in Sand Hollow's deep sand and high-speed desert, you need different valving than someone who mostly rock crawls at low speeds. Re-valving during a rebuild is the most cost-effective way to transform your machine's ride quality and handling without purchasing entirely new shocks.

We set up valving based on your specific machine, riding terrain, and performance objectives.

Desert Conditions &Shock Maintenance

Southern Utah desert conditions are among the harshest environments for shock absorbers. Fine sand infiltrates shaft seals, accelerating wear and introducing contamination to the shock oil. High ambient temperatures reduce oil viscosity, and extreme temperature cycling stresses seals. Washboard desert roads create sustained high-frequency shaft movement that generates heat and accelerates oil breakdown.

Regular shock service — including oil changes and seal inspection — is the most cost-effective way to maintain ride quality and extend the life of expensive shock absorbers. We recommend 40–60 hour service intervals for machines used at Sand Hollow and in desert conditions near St George and Washington, Utah.

Signs Your ShocksNeed Service

Shock degradation is gradual, and most riders adapt to the changing feel without realizing how much performance they've lost. Watch for a ride that feels floaty or wallowy, excessive nose dive under braking, body roll in corners, bottoming out on bumps that used to feel controlled, visible oil weeping on the shock body, harsh ride over whoops, or a noticeable reduction in rebound control.

On UTVs and side-by-sides, degraded shocks are especially noticeable at speed — the rear end kicks out, the front pushes through turns, and the suspension feels harsh without actually controlling the vehicle. If ride quality has changed or the shocks have more than 40–60 hours of hard off-road use, it's time for an inspection. A shock that used to feel plush now feeling harsh is a rebuild signal.

Frequently AskedQuestions

Do you rebuild shocks in-house or send them out?

All shock rebuilds are performed in-house at our Washington UT facility. We never outsource Fox, King, Elka, or Walker Evans shock service — that means faster turnaround and direct quality control on every rebuild.

Should I rebuild my UTV shocks or buy new ones?

For quality shocks from Fox, King, Elka, or Walker Evans, rebuilding is almost always the better value. A full rebuild restores OEM performance for a fraction of replacement cost, and we rebuild in-house so turnaround is fast.

How often should I rebuild my UTV shocks?

For UTVs used in Southern Utah desert conditions, we recommend shock service every 40–60 hours of operation. Deep sand, fine dust, and washboard desert trails accelerate seal wear and contaminate shock oil faster than in cleaner conditions. Machines ridden hard at Sand Hollow may benefit from even more frequent service.

What shock brands does MST Motorsports rebuild?

We perform in-house shock rebuilds for Fox, King, Elka, and Walker Evans — the major brands used on powersports platforms. Our service covers both reservoir and non-reservoir shocks, including bypass shocks and coilover configurations.

What does a shock rebuild include?

A full rebuild includes complete disassembly, shaft and body inspection, seal and bearing replacement, fresh shock oil, bladder inspection/replacement, internal component evaluation, and reassembly to manufacturer specifications. We also perform nitrogen charging on gas-pressurized shocks.

Can you re-valve my shocks for Sand Hollow riding?

Yes. Re-valving changes the internal shim stacks to modify compression and rebound damping characteristics. For Sand Hollow riders, we typically set up valving for high-speed desert stability while maintaining good low-speed compliance for rocky trail sections.

What shock upgrades do you recommend for Sand Hollow?

For Sand Hollow desert riding, we recommend Fox 2.5 or King 2.5 remote reservoir shocks with valving tuned for high-speed sand whoops and dune launches. We can re-valve your existing shocks or help spec a new setup.

How much does a UTV shock rebuild cost?

Shock rebuild pricing depends on the shock type (standard vs. reservoir), brand, and whether re-valving is included. Basic rebuilds are typically less expensive than purchasing new shocks and restore performance to like-new or better. Call 435-256-8899 for current pricing on your specific shocks.
