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. Shims with a 0.504" inside diameter are for Fox 2.0, 2.5 and some 3.0 shocks.
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.
