Product Description

The Bilstein B8 5160 25-311365 is a rear remote reservoir shock absorber engineered specifically for the 2007-2021 Toyota Tundra running up to 1.5 inches of rear lift. Its 46mm monotube body delivers consistent, fade-free damping tuned to match the Tundra's weight and suspension geometry, while the remote reservoir adds critical oil capacity to keep performance stable during sustained off-road use. This is the updated replacement for Bilstein's previous part number 25-237429 and fits all cab styles and both 2WD and 4WD drivetrains across the full generation.

Installation is a straightforward bolt-on at factory mounting locations - no modification needed. The included billet reservoir clamp and 360-degree swivel banjo fitting make for a clean, professional-looking setup. Whether you're daily driving a lifted Tundra or pushing it on rough terrain, the 25-311365 delivers the controlled, dependable rear damping the platform demands.
