Upgrade your 2022-2023 Toyota Tundra with the King Shocks 25001-397A performance shock kit, custom tuned to deliver improved ride quality, control, and suspension performance. Designed for the rear of the Tundra, this pair of 2.5-inch-diameter remote reservoir coilovers uses vehicle-specific damping curves and spring rates developed through dynamometer testing and demanding real-world evaluation. The result is a factory-tuned suspension upgrade engineered for consistent performance on the street, trail, and demanding off-road terrain.
External remote reservoirs increase fluid capacity and improve heat dissipation, helping the shocks maintain consistent damping during extended or aggressive use. The wide-range compression adjuster provides 20 precise clicks of adjustment, allowing you to fine-tune suspension response for changing loads, terrain, and driving preferences. Large shock bodies further support smoother, cooler operation, while the design delivers more than 20 percent additional wheel travel compared with the factory setup.
King Shocks builds the 25001-397A kit from extruded 6061-T6 aluminum using the same quality materials and precise tolerances associated with its Pure Race Series shocks. Improved reservoir mounts eliminate the need for hose clamps, while the high-strength stainless steel mounting pin, updated threaded end caps, and protective Schrader valve cap enhance durability and serviceability. Each shock is fully rebuildable, serviceable, and tunable for long-term performance.
This King Shocks rear coilover kit is a 100 percent bolt-on performance upgrade for compatible 2022-2023 Toyota Tundra applications. The kit includes a pair of remote reservoir shocks with compression adjusters and is designed to provide a controlled, dependable suspension solution without requiring custom fabrication.
