Our Triangulated 4 bar rear suspensions are made from heavy wall, seamless tubing and include urethane bushings. Bars are TIG welded for strength and appearance. Ride heights can be custom tailored to you taste during your installation. All bars have an one end adjustable to allow easy adjustment of the pinion angle. Frame rails must be boxed for bracket attachment points. Economic urethane bushings are standard with Ride Tech R-Joint as an upgrade.
We also custom build for non-stock frames or most vehicles not listed. Inquire for details. Vehicles must have trim-able inner fender panels for upper control arm clearance.
The kit are designed for steel housing rear ends, such as 8″ and 9″ Ford and 8 3/4 Chrysler rear ends, where steel brackets can be welded to a steel housing. These kits are not designed for Dana style rear ends that have cast housings. See our Parallel 4-bar for Dana style rear ends.
