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, heavy-duty rear pair suits Nissan Patrol GQ / GU models with long wheel base. 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. Our coil springs are manufactured on computer-controlled coiling machines, scragged before and after shot peening, load-tested and finished with a durable powdercoat finish.
