Installing new GMC Sierra leaf springs can freshen up your tired suspension, and will help give your vehicle the ride height and performance you desire. Simply adding lift or lowering blocks to your otherwise stock leaf springs can lead to axle wrap, which hinders stability, so new GMC Sierra leaf springs are a great way to prevent this from happening. If you still need more height or a lower stance after installing aftermarket leaf springs, a small block kit can help level your ride out and won't cause as many problems as using taller blocks would.

Aftermarket leaf springs are typically meant to lift or lower a vehicle, while at the same time adding some load capacity with a stiffer spring rate for better performance (some lowered leaf springs, however, actually have a softer spring rate for a better ride). Because of this, aftermarket GMC Sierra leaf springs generally help prevent axle wrap and offer better stability and cornering than their stock counterparts. While some GMC Sierra lift/leveling leaf spring kits come as complete leaf packs, others consist of separate leafs that must be added to your existing GMC Sierra leaf spring packs. Lowered leaf springs, in general, come as complete leaf packs and are ready to install.
