Product Description

Revmax is proud to offer you our highest performing solution to upgrading your 68RFE Transmission. The Revmax Signature 850 Combo Kit provides your rebuilder a complete ready to install package to upgrade your transmission. This is not just a box of parts, but rather a completely prebuilt and engineered kit that is ready to be installed. This kit is IDENTICAL to our 68RFE Revmax Signature Series 850 Transmission. We recommend this kit for trucks with up to 850RWHP.

The heart of this kit is our Revmax Billet Input Clutch Drum.  Our drum is available completely pre-built and clearanced, your builder does not need to do anything other than simply drop it into the case. *If the D.I.Y. drum option is selected you will need to machine parts and requires a lathe. Made out of a solid chunk of 6061 billet aluminum and then anodized in a Mil spec hard anodizing. The outer apply drum feature our Zero-Flex Technology and is constructed out of 6061 billet anodized aluminum and is nearly 2.5x thicker resulting the the most rigid possible apply setup. This drum features 16 high energy overdrive clutches, and 12 high energy underdrive clutches, custom OD / UD pressure plate and a custom OD / Reverse pressure plate. The drum is available pre-assembled, clearance.

The valve body is complete with an updated and oversized solenoid switch valve and our Revmax engineered accumulator springs, HD accumulator plate and custom fasteners. The valve body is also available in our tuneless option which requires no transmission tuning whatsoever and provides smooth shifting and converter apply with 235psi of line pressure!
