Product Description

The Bilstein 25-311884 is a high-performance front shock absorber in the B8 5160 series, specially engineered for heavy-duty trucks like the Silverado and Sierra 2500HD / 3500HD. It features a large 46 mm monotube piston paired with a remote reservoir to provide superior oil capacity, helping manage heat during sustained off-road driving or while carrying heavy loads.

Its digressive, self-adjusting valving adapts dynamically to terrain and load conditions, delivering a balance of comfort and control. The zinc-plated body resists corrosion, making it suitable for rugged environments. This shock is optimized for front setups with up to 1.5" of lift, making it a great option for lifted or leveled trucks.

Installation is straightforward using factory mounting points and the included reservoir mount hardware. Whether you're upgrading for improved off-road performance, better handling under load, or greater durability, the 25-311884 offers a reliable, tuned solution backed by Bilstein's 2-year warranty.
