Synchro hub (shifting sleeve) for 1st and 2nd gear 911 Turbo (75-76)

Our synchronizer hub (shifting sleeve) for the 1^st and the 2^nd gear is used as original equipment in the following vehicles:

     Porsche 911 Turbo 3.0 L (1975-1976)

This synchronizer hub slides on the gears’ shifting guide sleeves. When synchronizer rings begin to wear out, synchro hubs also become worn out. This causes gears to grind when shifting or to jump out of gear once engaged.

This synchronizer hub is used on vehicles with Type 930 manual 4-speed transmissions. It is not useable on the naturally-aspirated Porsche 911 or on vehicles that are equipped with Sportomatic transmissions.

Quantity required per vehicle: 2 (1 synchro hub / shifting sleeve for the 1^st + 2^nd gears)
