Custom Build Jeep YJ 4 Link Suspension

Years ago I built a lot of full width axle Jeep YJ’s while starting another company. Oddly enough one of the first builds I am putting together as I start a new company is a built Jeep YJ. In years past the builds took on a different form. In those days the hot thing was 1/4 elliptic suspension or buggy springs.

This Jeep YJ build is going to feature many new Motobilt parts you guys/girls will be able to purchase in kit form. We are going to 4 link the Jeep front and rear and install KING Coilovers front and rear. The suspension is something I have been thinking about for a long time. If everything goes as planned it will produce a kit that will be easier to install and set up for at home builders. The rear section of the frame has already been cut off. The plan there is to build a back half kit to make room for coilover shocks.

The Jeep has a Chevy Dana 60 front and 14 bolt rear. The tires are Super Swamper SX 43″ on 17″ Allied Beadlocks. The engine is the stock 6 cyl, stock auto tranny, and a Atlas t-case. I am not sure if the customer will change out the engine and tranny but I have a feeling he will at some point in the future. (Update: the customer has installed a chevy LS series motor and it does fit!)

I will do my best to update this post all along with pictures of the progress and parts used.
