JT5 5 Speed Model RC Enduro and Model CR 5 Speeds
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. Both gear sets have been successfully tested in engines exceeding 500 HP and putting out over 475 Ft. Lbs of Torque at 6500 RPM.
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.
