RevMax 700 Pro Series Input Drums

The RevMax Pro 700 Series input drums have a billet 1045 steel construction, eliminating any chance of the frictions digging into the drum, regardless of line pressure of OD piston diameter changes. The 700 Pro Series input drums are a drop-in design, no machining needed. Extensive testing was done to ensure that the additional rotating mass would not cause bushing issues. Tested to 700 hp, this drum is great for moderately modified trucks and can also be used in stock applications! In addition to RevMax 700 Pro Series input drums, RevMax also offers 850 and 12xR versions, as well as an oversized version that allows it to drop into a Sonnax Smartech drum without using a troublesome adapter ring.
