Description
**OS-88 TRANMSISSIONS ARE BUILT TO ORDER. LEADTIME TO SHIP IS ROUGHLY 6 MONTHS FROM TIME OF ORDER**
The OS-88 6-Speed Sequential Transmission is specifically designed to maximize RB26’s engine performance potential with tested and optimized gear ratios.
The “88” of OS-88 designates the distance of 88 mm between gear axes. By optimizing the gear tooth width and axes distance, we were able to maximize the size of gears used in OS-88 to achieve a significant increase in strength within the dimensions of a BNR32 / BCNR33 transmission. Along with its unique design, its components are manufactured with carefully selected raw-forged materials.
The result is a sequential transmission optimized for RB26, that can handle up to 1500 horsepower.
Aside from its optimal gear ratios and outstanding durability, we utilized a unique dog-ring structure and helical-cut gears to minimize the drivetrain noise and shifting efforts
-
Comes with bellhousing and shifter assembly
- Helical-cut gears for quieter street performance
- Non-synchromesh dog-ring structure
- For use in BNR32 / BCNR33, factory transfer case and prop shaft is reuse
-
For use in BNR34, BNR32 / BCNR33 transfer case and prop shaft is required
- Available with 3 different gear ratio options
