ARB TRED HD recovery boards are designed to deliver the ultimate level of performance for off-roading enthusiasts. Similar to the GT boards, HDs utilize a specifically-designed formula to rescue off-road vehicles, ATVs, or other equipment when traction has been compromised. TRED HDs are ready for heavy-duty action and heavy-duty recovery. The boards are made from a custom blend of high-quality engineered nylon, which allows the boards to flex from the vehicle's weight on unstable or uneven ground, providing a solid base for successful recoveries.
