Revmax 700S Pro Series Sonnax Style Billet Inner Drum

The RevMax 700S inner drum requires no adapter ring to be installed as the drum is machined to match the Sonnax drum perfectly. Using this drum allows the builders to run 16 single side OD clutches in the factory direction (facing up). The drum is coated with a Mil-Spec hard coat anodizing that resists steel impregnation. The drum can be built using factory full thickness UD/OD pressure plates or our billet UD/OD pressure plates. This drum will NOT work with a factory OD drum!

• Hard Mil-Spec anodized surface
• Allows up to 16 frictions in the OD clutch while keeping correct clutch facing
• Drop in design, no adapter ring needed with the Sonnax OD drum*
• Allows full thickness UD/OD pressure plate to be used with increased clutch counts.
