The Revmax Signature 550 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 550 Transmission. We recommend this kit for trucks with up to 550RWHP that are running a programmer and even an aftermarket turbo. If you are running an aftermarket turbo and fuel system then the Revmax Signature 850 combo kit will be needed.

The heart of this kit is our Revmax Re-Engineered Input Clutch Drum.  Our drum comes completely pre-built and clearanced, your builder does not need to do anything other than simply drop it into the case. This drum features 14 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 pre-assembled, clearanced and comes complete with all bearings and hubs. The valve body is complete with an updated and oversized solenoid switch valve and our Revmax engineered shift kit and accumulator plate.

This kit is desinged to be installed by a certified transmission rebuilder. A professional should be able to install this kit into your transmission in about 2-3 hours.

In order to increase pump output pressure you will need to have H&S Overdrive Software or purchase a line pressure box (available as an add-on item).
