Does anyone know if a 2pc drive shaft bolt on kit is made for a nnbs truck. After a put my 4.11 gears in. my truck started vibrating at about 85 mph. Im wanting to make a faster truck for a fun street / track truck.

I can make a new cross member but I was lookin for a bolt on
Thanks

 

I also plan to have a dual shaft setup. But I may take it to a drivetrain truck shop and get it done. I'll pay anything under 6/700 for the setup. I run 4.56 gears and 32" and I plan to spin the motor 7000+ Rpms. Driveshaft speeds should be double that. My driveshaft is short aftermarket already. But I would like a dual setup with driveshaft loops for saftey
