DYNATEK Two-Stage Rev Limiter Harley Davidson DRL400HD

Precisely controls over-revving and launch rpm. Designed for the odd firing angle of Harley V-Twins. Launch limit gives maximum off-the-line performance; adjusts between 2500 and 6250 rpm in 250 rpm increments. Spares unnecessary poundings of expensive engine components. Made in the U.S.A.. Not for Twin Cam.
