These 1.75" Coil Spring Spacers will sit on top of all Jeep Wrangler JK coil springs, adding ride height and ground clearance to the rear to increase the rake of your truck. With that extra height you'll have room for tires up to 33" in diameter giving your Jeep Wrangler JK that aggressive look, with no increase in cab noise or vibration, maintaining that factory smooth ride. These polyurethane bushings far surpass the durability of rubber, offering improved handling, lifespan, and performance.
