John Scott Posted September 21, 2000 Share Posted September 21, 2000 Just installed my new shorter driveshaft. 16.75 inches!! Keeps getting smaller! All spicer and ready to rock. He's done beautiful work for me over the last 20+ years. Wish my wages went up like his have over the years! Had an interesting conversation about 1/2 shafts and u joints vs cvs. He favors u joint set ups for really high hp. Said he sees too many failures on the cvs. I know in the stock form the cvs are the way to go over the stock u joints. Please educate me why, for the Z, the cvs are preferable when a really custom stout u joint 1/2 shaft can be made. JS Quote Link to comment Share on other sites More sharing options...
pparaska Posted September 23, 2000 Share Posted September 23, 2000 You have to consider that u-joints don't like angles of more that a few degrees when transmitting peak torque. The CV is MUCH mor e tolerant to this. When the Z squats on acceleration, the angles of the halfshaft u-joints are pretty severe (sorry, no numbers). I think that's why CV's are prefered on the halfshafts. If you are talking about a long driveshaft with small u-joint angles, then yeah, save the weight and money and us U-joints and not CVs.
