The Secrets to the Ford Bronco Raptor’s Suspension? Unusual Assembly and Beefier Parts

The mission of the 2022 Ford Bronco Raptor is the same as that of the Ford F-150 Raptor: Drive at highway speeds across a desert without, you know, shattering into many pieces. That requires a lot more suspension travel and careful distribution of the substantial energy generated when the suspension bottoms out on a big bump, or when landing off a jump. Here’s how the Ford Performance team modified the Ranger-based Bronco’s High-Performance Off-Road Stability Suspension (HOSS 4.0), so it could perform like an F-150 Raptor.

Overall suspension travel is down an even inch front and rear, relative to the larger F-150 Raptor’s, at 13.0 inches in front, 14.0 inches rear. However, both figures represent big jumps from the 8.0/9.8- and 8.7/10.2-inch front/rear travel on base and Badlands Broncos. Getting to that number required some dramatic changes to the frame and suspension components. The front upper shock/spring mount tower is raised 2.4 inches and significantly reinforced.

Because the new mounting location is necessarily more cantilevered off the frame, and because of the extreme jounce loads the Bronco Raptor must endure, the team needed to provide a second load path to share the bottoming-out loads with the internal jounce bumper inside the shock absorber. So the new cast lower control arm includes a jounce bumper that engages a new pad welded onto the frame. In the rear the frame includes mounting points for jounce bumpers on each side that simply engage the live axle to share the jounce loading with the shock absorbers.
