HF AP117 Air Locker – Jeep Wrangler/Cherokee (Rear)

Engineered for Jeep Wrangler / Cherokee

The HF AP117 Air Locker differs significantly from traditional designs like the ARB RD models. While conventional lockers rely on rubber seals that press against moving parts to hold air pressure—seals that wear out over time due to friction—the AP117 eliminates this weak point by using a piston-driven system. When air is applied, the piston pushes locking pins directly into place, instantly securing the gears. With no friction-prone seals to fail, the AP117 delivers a stronger, more reliable lock, offering greater durability and long-term performance in extreme off-road conditions.

It’s the perfect upgrade for off-road vehicles seeking dependable traction and improved off-road mobility.
