This is the only Hurst H-pattern 4 speed shifter approved by NHRA/IHRA for competition. It has been rebuilt, heavy duty linkage, and all new hardware. Has the reverse lockout required by NHRA. It is NOT a push down reverse, like the original Super Shifter. Hurst does not make these any more, but the parts and rebuild kits are available. I changed to a Doug Nash 5 speed, Hurst shifter is a complete kit for a Muncie, including the AutoGear Muncie M23.
