The EVO MFG JLU High Clearance Long Arm upgrade kit through specifically designed bracketry allows for ultimate in suspension and chassis clearance, larger wheel travel ability, optimal suspension geometry with increased ride quality. Clearance, ride quality, performance and ease of installation was our focus in creating this long arm suspension system. The front arms mount tucked up inside nearly flush with the bottom of the frame mounting inches above the stock front lower mounting bracket. The rear mounting locations for the long arm are on the side of the frame, above the bottom giving inches of clearance over the factory locations as well. Keeping optimal geometry while maintaining as much clearance was critical in the design of this system. In doing so, not only did we raise the rear control above the frame but we raised its mounting at the rear axle by multiple inches as well. This allows for an incredible ground clearance increase but just as importantly retaining flat and optimal control arm angles giving ideal ground clearance, smooth ride quality and long travel ability.The mounting brackets are specifically designed to require no exhaust cutting on 3.6L Jeep Wrangler JLU’s (minor grind/clearance to flange required) and have full length hard-face mounting surfaces that weld to your frame giving redundant and ample welding area and strength to their mounting. The mounting brackets align to the frame simply using existing factory holes giving complete assurance of proper locating during install. Simply bolt brackets up to frame with existing hardware and weld them in place. EVO MFG Long Arm joints feature Johnny Joints on both ends of the control arms for restriction free articulation and motion with no wearable and limited bond rubber. All long arms come complete with EVO1 on vehicle adjuster making alignment a snap allowing for the ability to adjust control arm lengths while completely installed on the vehicle at all times. All EVO MFG lower long arms are built with strength in mind. These arms are made from industry leading 2.0” x .281” wall Steel DOM Tubing. The EVO MFG JLU High Clearance Long Arm Upgrade is generally used to convert your current short/mid arm suspension to long arm by reusing some of your current suspension lift parts like coil springs, swaybar links, bumpstop extension etc saving you the cost of repurchasing these parts. This upgrade kit can also be used in combination with EVO Front and Rear coil over kits to maximize your vehicles on and off-road performance. Cutting and grinding of frame brackets required. Welding required.
