Skyjacker Suspension R3815 1.5in Rear Add-A-Leaf Spring Kit

The Skyjacker Suspension R3815 is a 1.5-inch rear add-a-leaf spring kit designed to increase load capacity and provide additional lift for your vehicle's rear suspension. This Softride® add-a-leaf is engineered to improve handling under heavy loads while maintaining ride quality for daily driving.

Key Features:

• Constructed from 100% American steel for superior durability and strength
• Shot-peened with hard steel pellets at high velocities to compress the surface and increase tensile strength
• Pre-drilled for center pin with application-specific pin location
• Long tapered ends provide progressive spring rate for improved ride comfort
• Increases load-carrying capacity while maintaining maximum wheel travel
• 1.5-inch lift height for the rear suspension

The shot-peening process is critical to the performance and longevity of these add-a-leaf springs, ensuring they can withstand the demands of heavy loads and off-road use without premature failure. The progressive design with tapered ends allows the spring to flex naturally, providing a comfortable ride when unloaded while offering the support needed when carrying cargo or towing.
