The K-Tuned Pro Billet RSX Shifter is a direct replacement for the OEM 2002-2006 RSX-S shifter box and was been designed to work with both factory and aftermarket shifter cables. The full billet design is extremely strong and eliminates all the flex and looseness that are felt with the stock plastic box. The shift lever and pivot ball are made from solid stainless steel and are seated in a spring loaded brass socket. This combination of stainless and brass allows the two materials to lap together while the springs push up and eliminate ñplayî at the ball. For mounting, there are two different sets of holes on the base, so it can be easily bolted into several stock and K-swap applications. The Race-Spec Billet RSX Shifter was designed for professional hard-core racers and we are pleased to offer them a shifter that is truly "Race Proven".
