JKS Manufacturing J-Max 3.5in Suspension System for 18-24 Jeep Wrangler Unlimited JL 4-Door

Quadratec Part #: 16156-0750
Description
As the name suggests, the JKS Manufacturing J-Max 3.5in Suspension System was designed to provide maximum suspension performance to your Jeep Wrangler Unlimited JL. This coilover conversion kit features FOX 2.5 Remote Reservoir DSC Coilovers and bolt-on brackets for premium handling and off-road ability. The included J-Flex control arms are made from 2in x .250-wall DOM tubing, and reduce Noise Vibration and Harshness (NVH) by using factory style rubber bushings. By including all eight adjustable control arms, the J-Max system provides optimal ride quality. To ensure that all suspension and driveline geometry is optimized, JKS also includes front and rear adjustable track bars.

Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
