These transmission belt pulleys allow you to change your final drive ratio for faster acceleration or lower RPM cruising on the highway. Installation notes - Changing the final drive ratio will affect speedometer reading; ECM adjustment or a Speedometer Calibration Module may be required to correct reading. Generally speaking, a 1-tooth change can be performed without a belt length change; more than 1 tooth may require changing belt length. Rear axle position adjustment required for each pulley tooth change is +/-.125" (3.2mm), while rear axle position adjustment required for each belt tooth change is +/-.280" (7.1mm). Check axle travel and availability of belts before ordering!
