Full IFS, 4WD chassis with triangulated trailing arm rear. Designed from scratch, utilizing the latest 3D scanning technology and our in-house engineering to create a one of a kind package for the 1966-77 Bronco.
Offering 12″ travel in the front and 13″ in the rear, we created this chassis with the smaller body of these classic trucks in mind. Dual rate springs optimize ride quality and performance working with 2.5 Fox Factory race series smooth body shocks. We also configured this package to accept Coyote/6R80 or LS/4L80 drivetrain packages with an Atlas 2 Speed transfer case. The RS4R chassis was also designed to allow the use of 285 series tires and +17″ wheels on all four corners without the need for fender opening mods.
