Fox Shocks 230-12-058-0 2nd Gen 2.0 Bump Stops 1-1/4" Diameter Hollow Shaft For 2-1/2" Stroke

Fox changed their 2" bump stop pads, pad holders and shafts. On their old style 1st generation bump stops the head of the pad's bolt and nut stuck out. On their new style 2nd generation bump stops the bolt head and nut are countersunk. When they made this change, they changed the diameter of the shoulder on the bump stop pad, the thread pitch on the pad holder and the thread pitch on the shaft (1-1/8"-16 TPI for 1st gen to 1-1/8"-18 TPI for 2nd gen). The easiest way to figure out if you have 1st gen or 2nd gen bumps is to look at the pad holder. See below example.
