The H-track shifter from S1 Sequential is our first go at a basic H-pattern shifter, rather than take the easy way out and make the same style shifter everyone else does we developed a unique floating pivot system that isolates fore and aft driveline movement from that of the shift knob. We also used an angular change multiplying linkage to keep the shift gate tight with the high shift knob position. These are made for the Tremec Tr-6060 but can easily be adapted to many other linkage type transmissions.
