Made a phone call to ProMotion. All I can say is wow! Those guys really know their stuff. One of the many questions that was answered for me was information about T-56 input shafts. I didn't know that there are multiple different designs for the 26 spline shafts! Just because the shaft has 26 splines does not always mean it will hold up to your power levels. ProMotion actually build shafts in house. Most of the company's out there offer upgraded shafts that are actually produced by Tremec and only hold up to about 600 hp. I can't run you through everything Wally explained to me, but if you have drivetrain questions I highly suggest you call them! I will be ordering a full shaft,clutch, flywheel, quadrant, adjuster from the with my tax return for sure!

Looks like Wally did his job well. :rolling:

Not many problems with any brand 26 spline shaft out there from what I've seen the past 5 years.

Hmm interesting, you guys got a hold of them! I have a D&D 26 spline input shaft I'm putting in mine this spring! I'm going to call them again and hope I can order up a clutch!
