RTS G101A Gforce 4 Speed Dogbox Transmission

Available "NEW" or "Refurbished"

RTS G101A side shift transmissions have UPGRADED ALUMINUM CASES on every transmission which is a much stronger and much longer lasting case than the old magnesium version.

ALL RTS G101A dogbox transmissions include NEW UPGRADED internals such as HD 3rd dog-ring face plates, and STEEL forks!

ALL RTS G101A racing transmissions have a double flat roller bearing in the tail housing to eliminate driveshaft slip yoke drag all the while handling much higher torque loads than the old school Cleveite bushings.
