OS Giken OS88 6-Speed Sequential Transmission

OS Giken OS-88 - 6 Speed Sequential Transmission to suit Nissan RB26

*Includes bellhousing and shift indicator*

Featuring multiple gear ratio options to maximise your engine's performance. Supports 1500 horsepower with outstanding strength and reliability.

In order to ensure outstanding strength and high quality, carefully selected raw materials are forged and manufactured from materials with increased strength. By setting the optimum tooth width and expanding the gear shaft distance to 88 mm, we have significantly increased the strength. We adopted a unique dog ring structure for a secure shift change and modest shift effort. Each unit is carefully assembled and carefully inspected, and only units which pass strict internal standards are shipped.
