The Gabriel 43181 Load Carrier Rear Variable-Rate Coilovers are engineered to enhance the performance and durability of vehicles under heavy-duty towing and hauling conditions. Designed for specific models of Chevrolet Silverado 1500, Suburban, Tahoe; Dodge Ram 1500; GMC Yukon; Jeep Gladiator; and Nissan Titan, these shock absorbers provide a reliable solution to maintain ride height and stability when carrying substantial loads. The shock absorbers feature a twin-tube internal design, a super-finished chromed piston rod to inhibit corrosion, and a leak-proof piston seal to extend product life. The D.O.M. (Drawn-Over-Mandrel) tubing reduces internal wear, ensuring longer product life. The variable-rate rear coil springs provide an additional 500 lbs. of load capacity per pair, helping to maintain ride height and improve stability under loaded conditions, without increasing the vehicle's payload. These features collectively contribute to improved vehicle handling, reduced wear on suspension components, and enhanced overall performance during towing and hauling operations.
