B&M's Short Throw Manual Shifters are CAD-designed and engineered as direct bolt-in replacement shifters - only simple hand tools are required for installation! Working with some of the top domestic and import racers, B&M's engineers took what they learned in the real world racing environment and designed a professional grade shifter. By designing in key features that makes these shifters the absolutely best you can buy (such as a counter-balanced bottom end) and incorporating a CNC 6061-T6 billet aluminum bearing mount (with a trick aerospace polymer spherical bearing), B&M Short Throw Shifters have become the professional's choice. Threaded for use with both factory and aftermarket knobs, these shifters feature counter-balanced bottom ends for more precise shifts. Extremely tight tolerances and spherical, long lasting high performance bushings or pivot locations make B&M Short Throw Shifters the smoothest, most accurate shifters available. The CNC machined, super tough 303 billet stainless steel shafts provide the absolute best leverage and reduces shift throw! The perfect choice for the serious domestic or import car racer. And B&M offers you a limited lifetime warranty. If performance means everything to you, let B&M give you the edge
