Built with the same quality of materials and precise tolerances found on our high end race shocks our OEM upgrade kits enable you to experience the famous King ride quality on your daily driver or pre runner. Built with race winning design features our kits come complete and provide simple 100% bolt on installation with no cutting or welding done to your vehicle.
Our front kits provide an adjustable ride height and a 25% increase in wheel travel. Rear kits allow a 15% travel increase. Large 2.5 diameter shock bodies with external reservoirs dramatically increase fluid capacity and heat dissipation to provide sustained damping performance even under the most punishing conditions. Our OEM upgrade shocks feature the same serviceable design that allows for valve adjustments with simple hand tools just like our race shocks. Our experienced shock technicians are a phone call away to help should any questions arise during installation or use. Our kits are available ready to bolt into stock vehicles or with custom length rod end for vehicles running lifted aftermarket suspensions.
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.
