Unparalleled Suspension – From Crawling to Fast Desert Driving

The first-ever TRUE production long travel suspension system for the 2021+ Ford Bronco. We engineered this kit to provide maximum performance under all conditions. Whether you’re crawling over boulders, climbing hills, or blasting across the desert, our ProRunner suspension system is designed to provide articulation and stability in the most unforgiving terrain.

Our rear long travel system utilizes a completely re-engineered upper shock mount, allowing for taller and larger diameter 3.0 internal bypass King coilovers with long-finned remote reservoirs and compression adjusters to deliver performance for extended periods with minimal shock fade. This is a fully adjustable 4-link long arm suspension system with rear track bar, made from 2″x 0.250″ DOM tubes, adjustable RockJock Johnny Joints for ultimate strength and serviceability. The long arm system is capable of 16.5″ of wheel travel, and designed for maximum articulation as well as smooth tracking on the pavement. The rear suspension system has an available King 2.0 adjustable bump stop kit with mounting brackets for a smooth landing when coming down or taking a hard hit. King 2.5 triple bypass shocks can also be added as an option, and will bolt onto the included upper and lower shock mounts.

The stock Bronco rear drivetrain is not well-suited for abuse on larger tires. This system comes standard with an APG re-enforced Ultimate Dana 60 rear axle, widened to match the 7″ wider track width of our ProRunner front suspension. The carrier is a standard 5.38 gear ratio with an electronic locking differential. The axle comes pre-tabbed for our suspension and includes all hardware to directly bolt into your Bronco. This allows you to get the most from your suspension system on 37″ or 40″ tires without the worry of damaging your drivetrain. Also included in the kit is an upgraded HD double Cardan CV rear driveshaft with 1350 U-joints for added strength.

This system is complete with all necessary hardware and mounting brackets, and requires professional installation and fabrication. THIS IS NOT A BOLT-ON SUSPENSION SYSTEM.

Our ProRunner rear long travel system includes the following:

  • Upper Long Arms W/Johnny Joints (pair)
  • Lower Long Arms W/Johnny Joints (pair)
  • Adjustable Track Bar W/Johnny Joints+ Upper Bracket
  • 3.0 Shock Tower and Frame Weld kit for lower links
  • Ultimate Dana 60 Rear Axle Assembly (5.38 gear ratio – electronic locking differential – 7″ wider than stock)
