Raceface Turbine SL Seat Post Service Tool Kit-like 398-00-916 398-00-838 398-00-894 This is a 4 piece tool set made to service/rebuild the Fox transfer SL and the Raceface Turbine SL dropper seat posts. 2 tools fit the 30.9 and 31.6mm only. The other 2 tools fit 30.9, 31.6 and 27.2. Please read the description further. These tools only fit the SL models All tools are CNC machined to a precise size out of 6061 -T6 aluminum. All are a raw machined finish. #11 This is for Top out (T/O) cap driver used to service a Fox Transfer SL and the Rockshox Turbine SL. This fits the 27.2, 30.9, and the 31.6 seat posts. This fits the same as fox part # 398-00-916 but this socket is an upgrade in how it is used. We made it so the socket slips over the upper seat post tube by a .300" at only .003" clearance to help stabilize the socket. Without the extra stability it is quiet easy to slip off the thin nut. #12 Tool is for a Retention Lug Driver for the 27.2, 30.9 and 31.6 Fox Transfer SL and the Rockshox Turbine SL. This is a similar fit to fox part # 398-00-838 #13 Tool is the sealhead driver that fits the outside collar on a Fox Transfer SL and the Raceface Turbine SL. This measures 1.47" across the flats. This will fit the 31.6 and the 30.9 but i dont believe it will fit the 27.2 size. This is a similar fit to fox #398-00-894 #14 Tool is for a Locking spring preloader. This fits Fox Transfer SL and Raceface Turbine SL in 30.9 and 31.6 sizes. This WILL NOT fit 27.2 sizes. It fits similar to fox # #398-00-935This auction is for the 4 tools in the primary pic only! No seatpost or seat post parts are included in the auction. Those pics are for reference only! It must be the SL versions of th turbine or transfer. It will not fit the non SL
