Direct-fit OE upgrade front shock for 1999–2007 Silverado 1500 and Sierra 1500 with coil spring front suspension. 2WD only. 46mm monotube nitrogen gas design at stock height. Not for Quadrasteer or ZX3 models. Made in the USA.
The Bilstein 24-029025 B6 4600 Series Front Shock Absorber is a direct bolt-on upgrade engineered for the 1999–2007 Chevrolet Silverado 1500 and GMC Sierra 1500 with 2WD coil spring front suspension. It replaces the front factory shock at stock ride height with a precisely tuned 46mm monotube design that delivers measurably better ride quality, handling, and front-end control — without any springs changes or modifications.
Unlike generic heavy-duty replacements that substitute brute stiffness for proper engineering, Bilstein's application-specific valving is calibrated for the Silverado/Sierra 1500's weight, geometry, and real-world use — whether that means smooth highway cruising, light off-road, or hauling and towing. The result is a front end that tracks confidently, resists dive under braking, and eliminates the imprecise, floaty feel of worn OEM shocks.
Stem upper / bar pin lower mounting — direct bolt-on for 2WD coil spring front suspension with no modifications
Fade-free front damping with cooler, more consistent performance than twin-tube alternatives under any conditions
Velocity-sensitive deflective disc valving reacts instantly to changing road inputs for confident, controlled front-end response
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty for the original purchaser
