Product Description

The Bilstein 25-325805 is a high-performance B8 8100 series rear shock specifically built for 2007-2021 Toyota Tundra trucks. Designed for lifted setups (0-1.5"), this shock features a large 60 mm bore and remote reservoir to provide increased oil volume and better heat dissipation, which helps maintain performance during off-road driving or under load.

Its digressive, velocity-sensitive valving offers excellent control by reacting smoothly to both slow and fast suspension movements. The gas-charged monotube construction ensures consistent damping without the foaming or fade that can occur under harsh driving conditions.

Installation is straightforward since this shock bolts into your Tundra's factory mounting points. The durable EVO-grey finish adds corrosion resistance, while the included reservoir mounting hardware simplifies the setup. Backed by Bilstein's 2-year warranty, it's an ideal choice if you want a reliable, high-capacity shock for lifted Tundra rear suspension.
