Product Description

The Tuff Country 10905 is a front shock extension and relocation kit designed as a companion component for the Tuff Country 13085 3.5-inch suspension lift on 2011-2023 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD in both 4x4 and 2WD configurations. When a 3.5-inch lift is installed, the factory front shock absorbers - designed for stock ride height geometry - can no longer travel through their full range without bottoming out or over-extending. This extension kit relocates the upper shock mounting point to accommodate OEM-length shocks at the new lifted ride height, eliminating the immediate need to purchase extended aftermarket shocks while maintaining proper suspension travel and ride quality.

Heavy-duty laser-cut steel brackets install at the factory mounting locations without modification, and all hardware is zinc-plated for corrosion resistance. This is a replacement/companion part for owners already running or installing the Tuff Country 13085 lift kit - it is not a standalone lift kit. Backed by Tuff Country's Limited Lifetime Warranty.
