Fabtech Part #: K4046B
Description
For JK owners that require the ultimate in offroad performance Fabtech offers a 5" Crawler system that will allow use of 37" tall tires for aggressive offroad use. The front system features a conversion from the factory 4 link arms to our proven Radius Arm design. The adjustable Radius Arm links are constructed of 5/16" thick steel for maximum dent resistance with rotational urethane joints at each end for unrestricted articulation. These new Radius Arms mount to a 1/4" thick steel crossmember that bolts to the frame under the transmission.

Check out the optional AEV ProCAL Module, a great finishing touch to any lift kit as it can reprogram your vehicles computer compensating for gear ratio and tire size changes after lift kit installation not to mention many other additional features.
Details

The front steering geometry is relocated via a dropped pitman arm. A Trac Bar relocation bracket keeps the arc of travel between the Trac Bar and Drag Link proper to reduce bump steer throughout the suspension travel.

Lift is accomplished with replacement Coilover Conversion system with Dirt Logic 2.5 Coilovers for maximum performance both on and offroad.

The rear system retains the factory 5 Link design but with extended length lower tubular arms that bolt to new side frame brackets. Installation of these frame brackets does not require the removal of the gas tank or welding. The upper links are replaced as well with a tubular style in the factory mounts. Both upper and lower links feature 5/16" thick wall links with adjustable rotational urethane ends. The rear Trac Bar is properly relocated to keep the rear axle tracking with the front axle for superior road handling at high speed.

For increased ground clearance at the rear axle, we provide replacement shock mounts that allow trimming of the factory mounts. This allows an additional 1" of ground clearance over the factory mounts. We offer heavy duty replacement driveshafts to be used with this system for maximum driveline reliability.
