King's new line of Original equipment manufacturer, (OEM), shock upgrade kits provides a bolt-on suspension system that elevates your on and off-road performance to unmatched levels. Each kit has been subjected to punishing real-world testing to develop the optimal damping curves and spring rates for your vehicle. 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 Prerunner. Large 2.5-inch 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 kits are available ready to bolt into stock vehicles or with custom length rod end for vehicles running lifted aftermarket suspensions.
