The EVO MFG 4.5" Jeep Gladiator JT Enforcer Suspension Systems lift your 2020+ Jeep Gladiator JT 4.5's. The JT Enforcer kits are specifically designed and engineered to lift your JL and maintain a performance spring rate, smooth ride quality all while retaining tow capacities. These kits allow for use of your choice of any aftermarket 2.5-5" lift shock or use of our EVO SPEC tuned 2.5" Remote Reservoir King Shocks. These kits come with a set of 4.5" lift springs specific to each corner which will keep the Jeep Gladiator JT level side to side. The difference with EVO MFG Enforcer Overland systems vs EVO MFG Enforcer systems is the use of front Overland Control Arm Brackets. When lifting your vehicle your control arms at ride height have a steeper angle towards the floor which can have some negative effect/chop in ride quality. With the use of the included Overland Control Arm brackets we relocate the front control arm mounting locations at the frame. In doing this when lifted we maintain factory flatter control arm angles and while minimal, we alleviate much of the chop associated with lifting a Jeep giving even better and more improved ride quality. Also, in the use of Overland Drop Brackets we are able to engineer more performance into the front suspension to improve braking and driveline angles through suspension cycle. Both kits drive very well, the Overland Kits are better suited for less hard off-road crawling and more light off road and on road use. The EVO MFG 4.5" JT Enforcer Kits are easy to install using normal tools. No drilling or cutting. They require no driveshaft or exhaust modifications. Simple Bolt on installation.
