Originally designed for TRUST/GREX sequential transmissions. Now, you too can feel the comfort and precision of our billet, CNC shift knobs. The OEM style screw type mounting makes installation simple and secure. The traditional knobs offer excellent comfort for both side and overhand grips. The counter-weighted shift knobs are engineered to be twice as heavy for a even better feel for hard shifts. While the super light knobs are a must for when weight and extreme climites are a concern.
