We have built a suspension package for your 1999 through 2006 Silverado or Sierra 1500 that includes everything you'll need for a complete replacement.
Leaf Springs:
Click the links below to learn more about each leaf spring version and their respective capacity differences.
3 Leaf | 4 Leaf* | 5 Leaf* | 6 Leaf* |
* The leaf springs are from the previous generation but can be mounted on the 99-06 1500 with eyebolt adapters (link) to save money.
Shackle:
The shackles on this generation of truck are well known for rusting through and failing. Don't risk your springs coming through the bed of your truck.
U Bolts:
This generation of GM truck requires 9/16 x 2.5" Square Bend x YOUR LENGTH.
The stock length varies by the block configuration with your leaf springs. If you're purchasing a heavier leaf spring, you'll need to compensate for the additional height by purchasing longer u bolts.
If you have a lift kit and need longer u bolts than we have listed, please order from this page (link)
