When traction is the difference between taking the checkered flag and being at the back of the pack, FOX Aluminum Bulb shocks give you the grip you need to be in the winner’s circle.

The large volume 2.25" bulb reduces shaft pressure gain throughout travel, greatly improving traction and consistency.


Base Valve Model: A racer-tunable base valve that allows low nitrogen pressure without cavitation, further enhancing driver input and producing even more bite.

BV R Model: To conquer constantly changing track conditions and multiple track setups, the 2.0 Aluminum Bulb BV R is equipped with a Low Speed Rebound shaft for on-the-fly, precise rebound tuning.
