The aFe RaceRunner Coil Springs is engineered to bestow optimum ground clearance to your Jeep Wrangler. By raising the front of your vehicle about 2 inches from factory ride height and the rear side at about 1 inch, you would be driving at a level height. This system is especially effective when moving across rough terrain. This innovation also improves vehicle control so driving across off-road environments is less stressful. What's more, these coil springs are heat-treated for consistency in performance.

These quality springs are made using chrome silicone materials for outstanding durability and the capability to handle even the most strenuous of circumstances. Crafted with emphasis on versatility, the RaceRunner Coil Springs are efficient with either factory or aFe RaceRunner Shocks. With their factory designed configuration, complicated procedures and tools aren't a necessity when generating a secure installation. Simple yet immensely beneficial, the RaceRunner Coil Springs are an essential fixture that improves the functionality of your Jeep Wrangler while systematically enhancing its safe travel.
