Save time, money and hassles when upgrading the transmission behind your rotary, this complete Rotary C4 Transmission Package provides you with everything you need to convert your car and features quality and most importantly proven components.
This newly-revised kit for 2022 now also features our brand new cast 1-piece H/Duty bellhousing which removes the need for a separate adaptor plate. Designed, developed and tested in-house, it requires no cutting or trimming of the case like some other aftermarket bellhousings which severely weakens the case and leads to premature failure. It has also been designed as compact as possible to allow it to fit within the bounds of a factory firewall/tunnel opening, meaning less fabrication or panel work, if any.
No running or ringing around trying to buy parts from a million different places and hoping they will work... This package is based on years of real-world R&D and testing, both on the street at race track and by offering a complete solution, we are able to guarantee the compatibility & quality of the combo.
And best of all, there's no waiting for your transmission to be built - We have at least 1 package on the shelf at all times, ready to ship!
