EVO MFG DIESEL/392 JLU High Clearance Long Arm Upgrade

The EVO MFG Diesel/392 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 Jeep Wrangler JLU’s 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 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

NOTE: compatible on 4dr. JL Unlimited only
