Our JK 3.5in Off-Road Pro Long Arm System is a race inspired system designed to take abuse. As JK's get older in years, they are getting wheeled harder and harder. The Off-Road Pro Systems are designed to minimize wear points while taking that punishment! As few as possible OEM mounting points have been used with this system. All ends of the control arms feature our Pro Series Krawler Joints so there are no bushings to break down from punishment. The suspension geometry features our tried and true independent 3 link design front and rear. There are no natural binding points, so the suspension cycles perfectly smooth. No system on the market today is ready for racing or absolute punishment like our Off-Road Pro Long Arm System.

- The Stretch System is designed for flat fender and stretch rear corner use. This will require body work.
- Welding of the Rear Cradle, Rear Third Link Mount, Front and Rear Long Arm Mounts is required.
- Removal of the OEM lower control arm mounts front and rear is required.
- Removal of the front upper control arm mount on the driver side is required.
- Minor exhaust rerouting required before the collector on the driver's side. This is recommended to be done prior to the suspension system being installed.
- Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up.
- We typically recommend 4.5in of back spacing on rims for 35in tall tires.
- We typically recommend 3.5in of back spacing on rims for 37in/38in tall tires.
-Will ride firmer than a system with bushings in the control arms, but will also handle tighter.
