Ironhead Sportster

Pictured is a late style Sportster cam gear kit, lower collars and pushrods made from either steel or aluminum. Steel pushrods are the best choice for stroker motors and drag applications where the greatest strength is needed. For street applications where quiet operation is desired, aluminum pushrods are the recommended choice. Both pushrod kits are made from 7/16 diameter tubing which will not interfere with rod covers. Lower spring collars are similar to late style H/D parts and will provide .060 more spring travel over stock collars. High lift cams are easier to install with these collars.
