IMCO Extreme HP SC Replacement Drive - Upper Only

421-01-83 + Option(s)

IMCO Extreme HP SC Replacement Drive - Upper Only

Our Xtreme Advantage SC drive upper units are available for those who may already own a IMCO, or a stock Bravo lower.

The Billet Aluminum top cap is supported by eight bolts with a controlled water-circulation system and built in spray nozzles to provide maximum cooling to the external upper gear case.

The steel tower in the floor is stabilized through internal lateral support beams to eliminate tower flex and gear deflection.

IMCO has developed a rigid pinion and bearing pack assembly with non-elastic shims to provide the correct rolling torque while stabilizing both input yoke and pinion. Tightened to 75 lb/ft, the pinion assembly is held in place by our plated steel ujoint retainer nut through a direct load-bearing path.
