This flywheel & pressure plate combination are 16 pounds lighter than a stock model A arrangement. Here's what you get: resurfaced & cut down flywheel, new ring gear, new pilot bearing, new clutch disc, new 6-bolt pressure plate, balanced. The benefits to this arrangement are less clutch chatter and a clutch that requires less effort to engage. Sold on exchange only, we must have your old flywheel and pressure plate before we can ship one of these units out.
