Sipple Max Effort HP90 (Hellcat, Redeye & Demon)

Sipple Speed and Performance Max Effort HP90 Transmission for Hellcats & Redeyes. 

We only offer one level of transmission the "Max Effort". These are the race proven, fully built transmissions. Billet E Drums, performance steels and frictions all assembled to SSP's precise specifications.

We don't just throw a bunch of clutches in and hope for the best. There is a reason Sipple's Max Effort Transmissions lead the lists online, and the winner's circle at the track.
