  • Extended Radius Arms: 15 inches longer than stock, designed to increase wheel travel and allow room for larger tires on a 6" lift.
  • Inward-Angled Design: Arms are angled inward to maximize tire clearance and reduce rubbing through steep suspension angles.
  • Pivoting Axis Rear Mount: Rear mounting bracket uses a pivoting axis to maintain alignment as the suspension articulates.
  • Complete Installation Kit: Includes mounting brackets and hardware for a straightforward upgrade to your existing 6" lift kit.
  • Vehicle Fitment: Specifically engineered for 1981–1996 Ford Bronco 4WD and 1981–1996 Ford F-150 4WD applications.

It’s a practical, purpose-built solution for trail use, overlanding adventures, and weekend excursions where suspension performance matters most.
