Description

Can’t stand your friends leaving you behind on the trail? Tired of busted u-joints, wheel hop, and broken leaf springs? Have you always dreamed of riding on a bed of clouds? Then the James Duff four-link is right for you!

What is a Four Link Suspension and why do I need one? Traction. The dual triangulated design keeps the tires on the ground- where you want them! Much like adding traction bars to a leaf spring suspension, the upper and lower links locate the axle but allow it to travel up and down and articulate without side to side and axle wrapping motion. This puts all your power to the wheels along with the added bonus of an amazingly smooth ride. Also, enjoy the benefits of reduced u-joint failure and an improved pinion angle.

Our new four-link system is for the Bronco enthusiast who wants to take their ride to the next level- but without all the fuss! The Early Bronco is one of the most challenging vehicles to properly set up for 4-link geometry. We spent the time and did the research to make this work. Let us save you the headache and hassle of buying the parts and pieces to build your own from scratch. Our dual triangulated four-link comes with everything needed for an easy install.

Truss designed to fit over the axle with minimal adjustment, frame brackets for the links can be installed where you want them, allowing you to stretch your wheelbase to your desired length. (rear cross member may need to be modified to clear axle truss if frame brackets are moved more than 2″ back past the stock wheelbase) Super beefy lower links, made out of the same tubing as our wildly popular radius arms. Upper links are made out of 1.5″ .120w DOM. Our truss, frame brackets, and link bars all come powder coated, choose our signature James Duff blue or our new Midnight metallic black. All hardware included with left and right hand 1″ rod ends for easy adjustment.
