Fabtech 8" Crawler System w/ Front Dirt Logic 2.5 Coilovers & Rear Performance Shocks w/ Stock Axles - 1987-95 Jeep YJ

In the late eighties and early nineties the Jeep YJ dominated the trail only to be replaced by the more capable TJ in 1997. Fabtech revitalizes the capability of the YJ with the introduction of our high end 8" Crawler System for 1987-95 Jeep YJ's. As a bolt on installation this system replaces the factory front leaf springs with our Dirt Logic 2.5 Coilover shocks and tubular Radius Arms as found in our TJ Crawler systems. The rear features a spring over design with Soft Ride Leaf Springs, extended length Shackles and a Floating Traction Bar. This Crawler suspension can be order as a complete system or as a separate front and rear system. Install this Crawler system with our optional high clearance 1/4" thick steel transfer case skid pan on your YJ and you'll leave the TJ guys behind.

Each shock has been pretuned specifically for the vehicle application providing a superior ride quality.
