B8 5160 Remote Reservoir Rear Shock

The Bilstein B8 5160 suspension shock absorber, part number 25-311365, is engineered as a direct-fit upgrade for lifted trucks and SUVs. Its robust monotube design ensures consistent performance and dissipates heat effectively through increased oil capacity, thanks to the integrated remote reservoir. This design also provides increased wheel travel, crucial for maintaining control over harsh terrain. The shock absorber utilizes digressive valving, which offers enhanced control over unwanted body movements while still providing good bump compliance. The B8 5160 features a smooth body with a 2.0-inch outer diameter and a 46mm piston diameter. It includes a 360-degree swivel banjo hose fitting and a billet reservoir mount for a clean, low-profile installation. The zinc-plated finish adds to its durability. Key specifications include a collapsed length of 386.5mm (15.22 inches) and an extended length of 653.2mm (25.72 inches), with a stroke/travel length of 10.50 inches. The lower mount type is an Eye (12.4mm) and the upper mount type is a Stem. The shaft diameter is 14mm. This shock absorber is non-adjustable for damping and does not come with a boot or spring seat, but does include reservoir mounts, washers, bushings, and nuts. Factory shock mounting bolts are reused for installation. This shock absorber is specifically compatible with the rear position for Toyota Tundra models from 2007 to 2021. Bilstein offers a Limited 2-Year Warranty on this product, protecting against defects in workmanship and materials for the original purchaser.
