This end loop is normally found on a Performance Series shock but beware that Fox uses two different thread lengths on their Performance Series shocks.

It's important to realize that anything 2.5" or greater, regardless of shaft diameter, all have 7/8" thread on the bottom. So for example, if you have a 7/8" shaft, 1" shaft, 1-1/8" shaft or 1-5/8" shaft, they all have 7/8" thread on the bottom. The problem is the length of the threads.

A common question that we get is, "can any Fox 7/8" threaded eyelet be used on any Fox shock?". It depends on the shaft and how deep the threads are on the eyelet. A Fox 2.0" shock with a 7/8" shaft and some Performance series 2.5" shocks have shorter threads on the shaft and the eyelet is threaded shallower than a Factory Series 2.5" or larger shock. See the example of the thread length on this shaft photo.

This eyelet has a 7/8"-14 thread pitch. It has "SHALLOW" threads. It can be used on a Fox bypass, smoothie, or coil over.
