ALL proper dogbox racing transmissions like the RTS G101A, GSR, 6XD have a double flat roller bearing in the tail housing to eliminate driveshaft slip yoke parasitic drag loss, all the while handling much higher torque loads than the old school Cleveite bushings. The double flat roller requires a “Hardened Slip Yoke”, this yoke is required for ANY dog-box style transmission!

RTS G101A, GSR, 6XD dog-boxes have an output shaft that is *32 spline to handle maximum power transfer, ALL racing Dog-boxes require a “Hardened slip yoke” for the front of your drive-shaft you are running.” You can also purchase this “Hardened Slip Yoke” direct from us; the additional cost is only $280.00

*Also a Special Thank you to FD series Championship driver Alex Heilbrunn who harshly testing the 6XD and was quoted saying “Not a single miss shift or hick-up all day and the mid-drift shifting is unreal”

Watch a test video here: 6XD 6 Speed Sequential Transmission Flawlessly Handles 1000+HP

“There’s nothing better than a racing product that you can set and forget, especially in the drifting world. 

The 6XD sequential is the perfect example of this.  Aside from fluid changes, we didn’t have to touch a single thing on this incredible gearbox for 15 events and secured a ProAm championship!

Without question, this is our gearbox of choice.”
