The Gabriel 13.5" Collapsed Length Ultra Truck Shock Absorber, model G64031, is engineered to enhance the ride quality and handling performance of light trucks and SUVs, specifically the Nissan Frontier and Suzuki Equator. This shock absorber is precision-engineered with exclusive G-Force„¢ technology, providing quicker response, longer life, improved comfort, control, and maximum shock performance. The G-Force„¢ technology includes a heavy-duty compression head for quicker response with reduced fade, an orifice control disk for consistent control, a sintered-iron piston for durability, a leak-proof piston seal that self-compensates for wear, a super-finished chromed piston rod for superior corrosion resistance, and a drawn-over mandrel (D.O.M.) tubing that reduces internal wear for longer product life. The shock absorber features a 1-3/8€ bore piston with bonded iron construction for durability and longer life, a super-finished chromed piston rod for superior corrosion resistance and enhanced sealing properties, and an OE-design single-lip oil seal that minimizes friction for optimal sealing. The gas-charged design provides quicker response with reduced fade, and the stableSteer„¢ valving improves tire contact with the road for control, safety, and performance. The orifice control disk with variable nine-stage valving provides consistent oil flow, and the boot included protects the shock from dirt and debris. The shock absorber has a collapsed length of 13.5 inches and an extended length of 21.19 inches, with a stroke of 7.69 inches. It is designed for easy installation without the need for additional hardware. This shock absorber is backed by Gabriel's limited lifetime warranty, ensuring quality and durability for your vehicle.
