ANDREWS 17 TOOTH REAR CAM SPROCKET. FITS 99 TWIN-CAM MOTORS.
Source: Custom Chrome
All Andrews cam kits for early Twin Cam 88® models require a new heat-treated 34-tooth rear cam drive sprocket and 17-tooth front cam sprocket. The new sprocket replaces OEM sprockets. As of winter 99, no Andrews Twin Cam 88® cam sets will be sold without one new drive sprocket. Sprockets are made from heat-treated alloy steel and are longer-than-stock for greater stability. A full-length 3/16" drive key and 3 spacer shims are included. With the shims, the installed length of new sprocket can be set to the same length as the original stock sprocket plus spacer. 34-tooth and drive sprocket will fit all stock Twin Cam 88® model rear cam shafts. If you are into any performance riding, a new sprocket is a must installation, even with engines using stock camshafts.
