Fox 2" Shock #90 Compression Shim Stack Set For 5/8" Or 7/8" Shaft Shocks Or 1-1/4" Shaft Air Shocks

The 1.570" thick top out washer (thick washer located just below compression stack) is NOT included in this kit because you should already have it in the shock if you're revalving it. We do sell them separately.

On the bottom cap, where the shaft enters the shock, Fox will usually stamp what valving they put inside the shock. For example 50/70 which is #50 compression and #70 rebound. Any time you revalve your shock, it's a good idea to replace the stover nut.

You can download any of the Fox shim stack charts below for reference. The lower the number is, the faster the shock reacts. The higher the number is, the slower the shock reacts. For example a #30 compression stack would compress MUCH faster than a #90 compression stack.

We also sell the shims individually because depending on how much of the valving you're changing, you might only need 1 or 2 shims, not an entire stack. For example going from a #45 stack to a #50 stack, only 1 shim changes.
