V long. The driving shafts are fitted with mechanics joints having needle bearings and appear to stand up very well, but the spline dia has been decreased to reduce tendency to stick under torque that we have noticed. These shafts move through 15º i.e. 4" bump & 6" rebound. The shaft mounting is insulated from the frame. They are now flirting with using torsion shafts for the main spring instead of coil or leaf springs Torsion Shafts 18" Rubber | ||
