Made of 7000 series aluminum, the 6-point socket has no lead-in chamfer and a low-profile design for a precision fit that minimizes scarring. They feature external knurling to increase finger grip and a durable anodized and laser etched finish. If you attempt to remove your fork&';s damper or spring top cap with a regular ol&'; socket it will most likely slip off of the top cap immediately and round off the edges. Don&';t risk marring up your fork and snag the proper tool for the job. 3/8" Drive Fox 36 & 38 Air Top Cap = 32mm Fox 36 & 38 GRIP Damper = 26mm Fox 36 & 38 GRIP2, GRIP X, and GRIP X2 Damper = 28mm Fox 36 & 38 FIT4 Damper = 26mm Fox 36 & 38 RC2 Damper = 32mm
