GM TH400 Heavy Duty Racing Transmission Billet Aluminum Direct Drum
MPN: PCE623.1010 UPC: 840136559313
<p>This TH400 Billet Aluminum Direct Drum is manufactured specifically for drag racing but also makes a great replacement for the hard to find OEM parts. Drum weights 55% less than the OEM drum.</p><p>Made from 7075-T6 Billet Aluminum, 36 element Pro Mod Sprag and new large steel outer race to allow the use of more clutches. Used in applications up to 3000 HP.</p>
