Bilstein 25-311853 is a B8 5160 Series front shock absorber for GM heavy-duty trucks. The 5160 pairs Bilstein's 46 mm monotube design with a remote (external) reservoir for added oil capacity and cooling, making it a direct-fit upgrade for trucks running a front leveling or lift up to 2.5 inches. A 360-degree swivel banjo hose fitting keeps the reservoir line low-profile and easy to route.

Fitment

Fits the front axle of 1999-2010 Chevrolet Silverado 2500/2500HD, 2001-2007 Silverado 3500(HD), 2001-2006 Silverado 1500HD, and the matching GMC Sierra 2500HD/3500/1500HD (2WD/4WD). Also applies to the Chevrolet Avalanche 2500 (2002-2006), Suburban 2500, GMC Yukon XL 2500, and Hummer H2.

Does not fit the rear axle - this is the front shock. It is valved for trucks with 0 to 2.5 inches of front lift; on a stock-height truck a shorter shock is the correct choice.

Sold As / What's Included

Sold individually (each). A full front pair needs two - order quantity 2. No spring seat, boot, coil, or torsion component is included; this is a shock absorber only.

FAQ

Is 25-311853 a shock or a full coilover?

It is a shock absorber only. It has no spring seat or coil - it does not raise the truck by itself and is meant for trucks already running a front lift up to 2.5 inches.

Is it sold in pairs?

No. Each 25-311853 is one front shock; buy two for the complete front pair.
