Builders run into limits quickly when trying to push a Jeep YJ further on stock width axles. The narrow track width and factory spring placement hold the vehicle back, especially when stepping up to larger tires and more aggressive rock crawling setups. Stability becomes an issue, and the factory front suspension layout does not support full-width axle swaps without major fabrication.
This is where a proper Jeep YJ full width axle conversion comes into play. The Motobilt system is designed to rework the front suspension layout so you can install a Chevy Dana 44 or Dana 60, along with select 1978–1979 Ford front axles. The kit widens the spring mounting points, moves the axle forward approximately 2 inches, and integrates a shackle reversal setup to improve suspension performance and approach angles.
The factory design places limitations on axle width and spring geometry. This kit addresses both by repositioning the leaf springs and providing the structure needed to support a wider, stronger axle. The included jig helps locate the rear shackle hangers through the frame, keeping everything aligned during installation.
Motobilt designed this system from real fabrication experience working on YJ builds. It is not a bolt-on kit. It is built for builders who understand welding, chassis layout, and suspension setup. The included stubby bumper, winch plate, and integrated recovery points tie the front of the chassis together while improving clearance and strength.
This system is commonly used as part of a larger build that includes wheelbase stretch, larger tires, and upgraded suspension. It keeps the ride height low while opening up room for proper suspension travel and axle articulation.
