Coil springs are one of the hardest working suspension components in a vehicle, supporting a vehicles weight, 24-hours a day. This TJM XGS spring coil, extra heavy-duty front pair suits Nissan Navara D40 and Pathfinder R51 vehicles with raised height. TJM XGS linear (or constant rate) coils provide a consistent spring rate in all situations. This coil spring design is suited to most 4WD vehicles to increase ride height, support high load bearing accessory (LBA) weight and improve stability. Ideal for vehicles with upgrades like steel bull bars and winch combinations. Your original factory springs will often be subject to fatigue and reduced performance when subject to additional LBA weight or use in extreme environments.
