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.
Click the links below to learn more about each leaf spring version and their respective capacity differences.
* The leaf springs are from the previous generation but can be mounted on the 99-06 1500 with eyebolt adapters (link) to save money.
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.
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)
