    Dead-hooking a car that makes north of 1000whp means certain death for nearly any driveline – except Bret Bradbury's. With RKT56's help, Bret's driveline will continue to serve him well.

Cassidy Nolen joins RKT56

Cassidy is a SCCA driving instructor and will be testing the RKT56 prepared drivetrain under road racing conditions. Road racing conditions are  different than drag racing or street conditions in that the trans/differential will produce a lot more heat. The prolonged time in that envoirnment will break down the fluid if it’s not kept cool. [...]

Customer Testimonials

I wanted to let you know that I pulled the vette out of storage and the car runs great. The tranny shifts perfectly. It is weird to be able to drive the car without having to double clutch 4th. I just want to let you know how appreciative I am of the great work and communication you shared with me. Let me know if I can help you out with anything. You will definitely be the one to build my diff when the time comes.
— Alex H

I just want to thank Rick for the superb job he did on my car. This dude is like the superman of transmissions. Last Saturday he pulled in my driveway at 10 am and had pulled the trans and installed the clutch before noon. Today he came and had the trans back in and ready to go in under an hour. I still cant believe it.
