Detailed Description

This Dorman coil spring is designed as a direct replacement for the original equipment spring on specific Chevrolet Silverado 1500, GMC Sierra 1500, and related Classic models. The 5160H alloy construction and powder-coated finish support corrosion resistance and stable performance, while the constant-rate design helps maintain predictable suspension behavior under load. Part number 929-958 is intended for severe heavy duty front applications where the original spring has sagged, weakened, or no longer maintains ride height.

This part cross-references GM 25876854 for the same application.

What It Is Used For

  • Restoring front ride height after spring fatigue or sagging.
  • Replacing a worn coil spring that no longer supports load properly.
  • Addressing uneven stance caused by weakened suspension components.
  • Maintaining consistent front suspension response in heavy-duty use.

Installation Notes

Fits 1999-2006 Chevrolet Silverado 1500, front. Fits 2007 Chevrolet Silverado 1500 Classic, front. Fits 1999-2006 GMC Sierra 1500, front. Fits 2007 GMC Sierra 1500 Classic, front. Verify severe heavy duty application details before installation and confirm spring orientation, end type, and installed height against the original part. Professional suspension service is recommended because coil spring replacement requires proper compression and safe handling procedures.
