Made for the real drivers car, we are excited to offer our new Turner Shift Knobs. Our mission was to develop a shift knob that helped connect the driver to the car. There is something about having a third pedal and direct engagement with your gearbox that makes driving worth all the time and money spent on your BMW. Every once in a while a product a product comes out and you just have to think to yourself "how could it get any better than this?" There are many shift knobs out there but none like our Turner weighted shift knobs. A combination of the correct size, shape and weight paired with the durable but smooth Delrin exterior gives you the driving experience that cannot be matched by anything else on the market. Our weighted shift knob is superior for its enhanced shifting capabilities and resistance to temperature change. No more hot shift knobs in the summer and bone chilling shift knobs in the winter, the Delrin exterior provides a barrier between extreme temperature changes for a truly enjoyable experience.

Our Turner Motorsport's in-house engineered billet aluminum shift knobs have been carefully designed and tested to bring you one of the highest quality and greatest interior enhancements available. Our shift knobs start out with a piece of billet 6061-T6 aluminum that gets CNC machined for a precision fit and finish. The aluminum components are anodized with an extremely durable and long lasting type II finish. Unlike many others on the market, our Turner shift knob features a groove where the seam of the wrapping insets so there is a smooth appearance and feel. The lower "boot lock" securing nut was carefully designed to provide a clean, OEM style seal between the knob and the shift boot by allowing the boot end to tuck down inside it. Weighing in at a shift smoothing 340g, the knob will enhance the shifting experience and pairs extremely well with Turner's short shift kits to give a full shifter makeover! OEM shift knobs have an average weight of 175g; the substantially heavier weight of Turner's shift knob will smooth out shifts resulting in faster engagement and a much better feel. Up to 179% heavier than your stock knob!

Features:

Anodized billet aluminum core
Extremely durable Delrin outer construction
340g up(11.99oz)
5 Speed Coin
Anodized billet shift boot collar with Turner logo engraved
Shift knobs are available in both 5 and 6 speed variants.
