The EVO MFG 2.5"; JL Enforcer Lift Suspension Systems lift your 2018+ Jeep Wrangler JL 2.5";s. Our main goal in developing this kit was to give a smooth ride on and off road while giving additional lift with increased performance. The JL Enforcer kits are specifically designed to lift your JL and maintain compliant spring rate, smooth ride quality while having the option of retaining factory shocks, maintaining full wheel travel with use of shock extensions (part number EXT kits) or without shock extensions to allow for use of your choice of aftermarket 2/2.5"; lift shocks. These kits come with a set of 2.5"; Plush Ride Lift springs specific to each corner which will keep the Jeep Wrangler JL Level side to side and will maintain a unique and compliant ride quality. EVO MFG JL Enforcer kits are available in multiple configurations to suit your needs and budget and are upgradable down the road. These Enforcer kits will fit up to a 37” tires on Rubicon Model JLs or 35"; tires on Sahara and Sport/S. The EVO MFG 2.5" JL Enforcer Kits are easy to install using normal tools.
