Drivetrain Components


With combined efforts of C&R and Xtrac, the CR2C is the premiere Transmission for the NASCAR market. Utilizing years of F1 and Indy car knowledge, the CR2C is the first NASCAR approved transmission to have an Independent Shaft System. This allows for far less gear deflection due side loads from misalignment of bell housing and driving angles. This cutting edge design keeps the main shaft independent from the output & input shaft; allowing the gear set’s to run in their optimal locations.

Xtrac’s advanced engineering and quality are the backbone of the CR2C with the lightest rotating weight on the market. All shafts, gears, and shift mechanisms are manufactured in their UK facility, and held to strict tolerances. The utilization of Xtrac’s full form gear ground design, optimizes the strength while reducing the overall weight. In meeting NASCAR requirements for COT, the CR2C incorporates easily adjustable ballast to ensure the transmission is always at the minimum weight. The main case and mid plate assembly are aluminum with the option of steel covers for added adjustability.


C&R manufactures all components of the CR1 Transmission at the Indianapolis facility, except for the internals and case. This allows C&R to maintain greater control of tolerances. Pictured are the CNC Shifter Handles, Shifter Knob and CR1 Top Plate Cover.
