    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!

    Upgrade the suspension on your Harley® with the high quality IKON adjustable shock absorbers and premium fork springs. A suspension upgrade is one of the best improvements you can make on your motorcycle, fully transforming the riding experience for both the rider and passenger. For the rear, IKON shocks are fitted with progressively wound springs that soak up small bumps smoothly and get increasingly stiffer as they travel, so you don't experience back-jarring bottoming on bigger road irregularities. To improve control, 4-position rebound damping is adjusted without tools by simply turning a dial located at the top of the shock, and three levels of spring preload is set using the included spanner wrench. Several lengths are available to allow you to raise, lower or maintain the factory ride height of your motorcycle. For the front, IKON's progressively wound springs replace the spongy factory units for improved ride and control when ridden aggressively. Both are surprisingly affordable, excellent upgrades and are easy to install. To measure the length of your shocks, raise the rear wheel off the ground or fully extend the rear suspension to measure the center-to-center length of the shock absorber at the center of the mounting bolts.
