What is shot-peening and why is it important for these leaf springs?

Shot-peening is a process where the steel surface is bombarded with tiny steel pellets at high speed. This compresses the surface, increasing the steel's tensile strength. For these leaf springs, it means they are stronger and more durable, allowing for better performance and a longer service life.

Will this kit change the ride quality of my truck?

Yes, these Add-A-Leafs are designed to improve your truck's load capacity. Many applications feature long tapered ends, which help create a progressive effect. This means the ride should remain comfortable during normal driving but offer increased support when the suspension is under load.

Does this kit come with all the necessary hardware for installation?

The manufacturer description states the leaves are pre-drilled for the center pin, and pin location varies by application. It does not specify if additional hardware beyond the leaf springs themselves is included. Refer to the manufacturer's installation instructions for a complete hardware list.

Product Details

Skyjacker is known for making suspension components that can handle tough conditions. This Add-A-Leaf kit, part number R1115, is designed to give your truck a bit more carrying capacity. It's a popular way to add some extra support to your rear leaf springs, especially if you haul heavy loads or tow regularly. This kit fits a range of trucks, including models like the Chevrolet Silverado 1500 and GMC Sierra 1500.

These aren't just any leaf springs; they're made from American steel and go through a shot-peening process. This means the surface of the steel is compressed with high-velocity pellets, which actually increases the steel's tensile strength. This makes the leaf stronger and helps it last longer, allowing for better wheel travel and a more comfortable ride without sacrificing durability. The ends are often tapered for a smoother transition, contributing to a more progressive feel when the suspension is loaded.

The kit comes pre-drilled to accept the center pin, and the pin location is set for the specific applications it fits. This attention to detail helps ensure a proper installation and that the leaf spring functions as intended to support your vehicle.
