Jeep JL Wrangler consumers are demanding a well-engineered, high-quality, off-road coil spring lift solution that delivers increased stance and the ability to install larger wheels and tires, all while maintaining that all-important factory ride comfort on the street and improving JL's renowned off road capability. Using a decade's worth of engineering science derived from our popular JK & JL SST lift kits, our R&D team created new versatile custom linear coil spring lift kits featuring increased spring rate. This revised spring rate translates to a much improved overall ride on the street while preventing the Jeep JL Wrangler from settling or sagging with the added weight of heavy bumpers, winches and other off-road related accessories. The 69-6827 Coil Spring Lift Kit provides 2.5 inches of front lift and 2.0 inches of rear lift on JL Rubicon with clearance for up to 37" tires, Sport/Sahara can accommodate up to 35" tires.. The 69-6827 Coil Spring Lift Kit features four hot wound linear springs with increased spring rates and a durable powder coat finish for care free corrosion protection on or off road. These springs don't just maintain the factory ride - they improve the ride and handling! Kit includes CNC-bent laser cut steel shock extensions for both the front and rear and utilize an offset design to retain the factory shocks at an ideal angle for lifted situations and preserve factory ride quality. This all-new Coil Spring Lift Kit go beyond the basics and includes longer sway bar end links as well as custom-tailored bump stop extensions. These new bump stop extensions are an essential component when lifting the new Jeep JL. NOTE: Not compatible with diesel engine.
