07-18 Wrangler JK 2 Door 3 Inch Lift / 4 Door 2.5 Inch Lift Coil Spring Pair Rear TeraFlex

The TeraFlex 1854102 is a rear lift coil spring kit engineered specifically for Jeep Wrangler JK (2007–2018) models. These heavy-duty coil springs are designed to raise the rear suspension, providing approximately 2.5 inches of lift on 4-door JK Unlimited models and about 3 inches on 2-door JKs, which gives extra ground clearance for larger tires, aftermarket bumpers, winches, and other gear without sacrificing ride quality. Built with a linear rate design, the springs offer a balance of on-road comfort and off-road performance, and are shot peened and powder-coated for enhanced durability and resistance to corrosion and fatigue. Sold as a pair for the rear axle, the 1854102 springs help maintain proper suspension geometry and improve overall handling on lifted Jeep setups.
