With the long standing success of the original Model RC gearbox. We have been working hard to improve the power levels as well as compatability with existing race transmissions commonly used in endurance applications. The newer RC Enduro gear set includes a wider tooth profile, 9310 alloy gears, improved bearing design, optional Magnesium tailhousing, billet top cover, rollerized 5th gears, one piece mainshaft, and 26 spline 1 1/8" input shaft.

The model CR ( "Club Racing" ) 5 speed also uses 9310 alloy gears that use synchronizer rings. The agressive tooth profile produces a slight gear whine similar to the older M22 Muncie 4 speeds. These gear sets are designed for the performance minded enthusiast that needs a close ratio streetable gearset for club racing events or classes that require a full synchro box. You can order this box with the standard casing or with a magnesuim tail and billet top cover.
