8100 Rear Shock Pair (With Options) | 2007-2021 Toyota Tundra

Build your 2007-2021 Toyota Tundra rear suspension around your driving needs with a matched pair of Bilstein B8 8100 shocks. Choose Smooth Body, DSA Adjustable, or Adjustable Bypass. Every selection includes the correct left and right rear shocks.

Built for Repeated Suspension Work

All three configurations use a 60mm piston, a 2.65-inch outside-diameter body, and reservoirs to increase fluid capacity and manage heat. They pair naturally with 8112 front coilovers, while allowing you to select the rear damping system that suits your truck.

Choose Your Rear Shocks

8100 Smooth Body

Includes 25-294118 and 25-325805. Vehicle-specific digressive valving provides damping without external adjustment. A straightforward choice for daily driving and trail use when you prefer a preset calibration. Fits applications with 0-1.5 inches of rear lift. Wheels must have no more than 6 inches of backspacing.

8100 DSA Adjustable

Includes 25-294125 and 25-328929. Adds independent high- and low-speed compression click adjusters. Tune body-motion control separately from response to faster impacts as your route or load changes. Adjuster speed refers to shock movement, not road speed. Fits applications with 0-1.5 inches of rear lift. Wheels must have no more than 6 inches of backspacing.

8100 Adjustable Bypass

Includes 25-326048 and 25-326055. External bypass passages add position-sensitive damping, with separate compression and rebound adjustments. This provides control over how the rear suspension compresses and returns through its travel. Choose this configuration when you want additional tuning for demanding off-road use. Fits applications with 0-2.5 inches of rear lift.

Fitment and Setup

• For 2007-2021 Toyota Tundra rear applications.
• Rear shocks do not create rear lift. Lift height comes from the leaf springs or other lift components.
• Verify shock travel, bump-stop engagement, and wheel and tire clearance with your installed suspension.
• Damping adjustments do not increase payload capacity or replace springs appropriate for the load.

Included

One left and one right Bilstein 8100 rear shock in the selected configuration, with associated reservoir mounting hardware. Front coilovers, leaf springs, and rear lift components are not included. Price is for the pair.
