Skyjacker YJ45K-H 4-Inch Rock Ready Suspension Lift Kit with Hydro Shocks

The Skyjacker YJ45K-H is a complete 4-inch Rock Ready suspension lift kit with Hydro 7000 shocks, engineered for the serious off-road enthusiast. Built around Skyjacker's signature Double Military Wrap Leaf Spring technology, this kit combines the proven Softride leaf spring design with a heavy-duty military wrap for superior strength, axle torque control, and main leaf protection under the most demanding trail conditions.

The Rock Ready leaf springs are shot peened to increase tensile strength and long-term durability, and are 100% cycled and pre-set at the factory — eliminating any break-in period and ensuring a defect-free installation from day one. Tapered leaves with Teflon tip inserts distribute load evenly across the entire spring pack, delivering more flex at the leaf ends and a noticeably smoother ride on- and off-road. The Double Military Wrap design spreads load from the main leaf across the two top leaves during articulation, dramatically extending spring life in repetitive, punishing conditions.

Included Hydro 7000 shocks are hydraulic units specifically designed for use with lifted suspension systems. Unlike high-pressure nitrogen shocks, the Hydro 7000s are tuned to complement the Softride spring rate for a compliant, comfortable ride that doesn't sacrifice off-road capability.
