Direct-fit OE upgrade front shock for 1988–2000 Chevrolet and GMC K-Series trucks, Tahoe, K1500 Suburban, Yukon, Blazer, and Cadillac Escalade at stock height. For rear leaf / torsion bar front suspension. 46mm monotube nitrogen gas design. Made in the USA.
The Bilstein 24-104050 B6 4600 Series Front Shock Absorber is a direct-fit OE upgrade engineered for the entire GMT400 full-size truck and SUV platform — covering Chevrolet and GMC K-Series pickups, Blazer, Tahoe, K1500 Suburban, Yukon, and even the first-generation Cadillac Escalade. This single part number covers a broad range of the most iconic full-size 4WD trucks and SUVs ever built, all sharing the same torsion bar front suspension design.
Precisely valved for the torsion bar front suspension on these platforms, the 4600 series delivers improved steering response, reduced front-end float, better stability through lane changes, and more confident handling on and off the pavement — all without any lift or modification. Whether your truck is a stock workhorse, a Z71 off-road rig, or a loaded SUV, this is the most cost-effective upgrade you can make to restore and improve front suspension performance.
Engineered for rear leaf / torsion bar front suspension — the standard GMT400 4WD configuration
Fade-free front damping for trucks, SUVs, and loaded applications — cooler and more consistent than twin-tube designs
Covers K1500/K2500/K3500 pickups, Blazer, Tahoe, Suburban, Yukon, and Escalade across the full production run
