Early Bronco Extreme 4 Link Suspension

Description

The James Duff Extreme 4 Link Suspension is engineered for those who demand a superior off-road experience without the complications of custom modifications. This system features a dual triangulated design, ensuring optimal tire contact with the ground for maximum traction. By utilizing upper and lower links, the suspension allows for vertical travel and articulation, minimizing axle wrap and enhancing pinion angle for reliability and strength on challenging terrain.

Key benefits of the four-link suspension include:

– Elimination of leaf spring limitations, greatly enhancing ride comfort
– Compatibility with standard 9″ and Full width 9″ axles for both 3.5″ and 5.5″ lifts
– Options for one-ton axles, specifically tailored for Dana 60/70, Sterling 10.25/10.5, or Corporate 14 Bolt setups with 5.5″ lift
– A complete installation kit that includes all necessary components for a straightforward installation, significantly reducing the complexity of DIY builds

This suspension system is specifically structured for easy installation:

– A minimum body lift requirement of 2″
– A truss designed for optimal fit over the axle with minimal adjustments; welding is required
– Integrated upper and lower link mounts in a single-piece weld-on frame bracket design
– Complete elimination of axle wrap and incorrect pinion angles, leading to a decrease in the failure of critical driveshaft components
– Reduction of wheel hop and elimination of broken leaf springs
– The option to enhance on-road handling with an additional rear sway bar kit while maintaining excellent off-road traction and articulation

Advanced materials ensure durability and performance:

– Heavy-duty lower links, constructed from the same high-quality tubing as our renowned radius arms
– Upper links fabricated from robust 1.5″ .120w DOM tubing
– Available in a striking powder-coated finish, choose between our signature James Duff blue or the sleek Midnight metallic black
– All required hardware is included, featuring easy-adjust left and right-hand 1″ rod ends

Installation requires welding and modification of the exhaust system. Additionally, it may involve relocating brake lines, brackets, and e-brake cables.

Note: This suspension system is incompatible with James Duff Dual Exhaust; serious modifications are necessary for compatibility with James Duff 2 into 1.
