Direct-fit OE upgrade front shock for Silverado/Sierra 2500/3500, Avalanche 2500, Suburban 2500, and Yukon XL 2500 at stock height. Independent front suspension. Hardware included. Not for Quadrasteer or ZX3. Made in the USA.
The Bilstein 24-060813 B6 4600 Series Front Shock Absorber is engineered as a direct-fit OE upgrade for the GMT800 heavy-duty truck and SUV platform — covering Chevrolet Silverado and GMC Sierra 2500/3500 series trucks, the Avalanche 2500, Suburban 2500, and Yukon XL 2500. These are trucks and SUVs built to haul heavy loads, pull serious weight, and cover high mileage, and the 4600 series front shock is precisely tuned to match that mission.
With independent front suspension and the demands of 2500/3500-class loads, worn front shocks on these platforms show up as reduced steering precision, front-end wander under load, and diminished confidence during lane changes and evasive maneuvers. The 46mm monotube design restores and improves all of that — delivering better front-end control on the highway, improved stability under tow, and a more planted, responsive feel on any road surface.
Mounting hardware is included with this shock — unlike many other 4600 series applications
Fade-free front damping under sustained 2500/3500-class loads — consistent performance mile after mile
Application-tuned for heavy-duty truck use — improved front stability under tow and with heavy payloads
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty
