This 1-3/4" Coil Spring Spacer Lift Kit fits all 2007-2018 Jeep Wrangler JK models. Sitting on top of the coil springs, the spacers act as a lift kit, increasing both ride height and ground clearance. The extra room creates space for tires up to 33" in diameter, further increasing ground clearance, ride height, and off-road capabilities. The included bump stops prevent your suspension components for colliding when at full bend in the toughest off-road environments. These spacers and bump stops have increased durability and lifespan, offering significant performance advantages to the rubber alternative.
