SDG Standard Service – Race Precision, Factory Fresh

The SDG Standard Service brings your shocks back to race-ready precision. Each unit is fully disassembled, cleaned, and rebuilt with SDG-spec or OEM seals, refilled with Fox JM92 fluid for thermal stability, and vacuum-bled to eliminate trapped air. Every shock is nitrogen-charged and leak-tested to restore consistent damping and fade-free performance.

Ideal for UTVs, SxS, Trophy Trucks, and prerunners needing a seasonal refresh or reliability before race day.
