King OEM Performance Shock Upgrade Kits are direct bolt-on replacement shocks and/or coilovers for your vehicle and come custom tuned for the ultimate balance of on-road handling and off-road performance. They include all of the necessary hardware you need for a bolt-on installation that can easily be done over the weekend. Custom length shafts and cylinders are available to work with any brand and size lift kit. Additional options include compression adjusting reservoirs, custom colors, internal or external bypass tubes, and race-spec valving.

Servicing, Tuning, and Rebuilding
All OEM upgrade shocks and coilovers are hand-built with the same parts as all of King's other Performance Race Series shocks. They are completely serviceable, tunable, and rebuildable to last a lifetime and it only requires a few simple hand tools, a few hours, and the appropriate King replacement parts from Filthy Motorsports. If you prefer not to do the work yourself, you can always bring (or send) your shocks to us and we will service them for you.
