Ultimate Billet Steel Front Drum
22555BSWR Made from 4140 steel w/retainer
Manufactured from 4140 steel, this drum will be a must for pro-street transmissions. This drum helps prevent the violent explosion that occurs when the over-running clutch (the sprag) fails. This offers more protection than the stock drum, without the service intervals of the aluminum drum. This drum was tested and it went to 32,000 RPM without failure.
