Just a warning to any serious stick shift drag racers. Spend the extra cash and get a real slip yoke! So far I've mangaged to twist 2 PST slip yokes. The first one was the cast slip yoke. That one twisted like a pretzel. The second one I had PST upgrade me to a their forged slip yoke. Apparently it only took 2 passes to twist that one I had to use an air hammer to get the damn thing out the back of the tranny. Now I'm gonna try out Moser's billet slip yoke http://www.moserengineering.com/othe...50-series.html. My car is a H/C LS1 with a 175 shot, built T56 Moser 9" on Hoosier 28x10.5's.

Wow! Is the driveshaft long enough? I could see you having problems if the driveshaft is too short. This is the first I have heard of the forged yoke causing problems. Bob

Wow! You're running 1.40 and almost in the 9's with a 27 spline output! Or did you mean to link to a 30 or 31 spline yoke?

The standard slip yoke is cryo treated. Bob

No, its still the stock 27 spline mainshaft. Some time in the future, I'm going to be upgrading to a 32 spline SSR mainshaft.

i just replace my 2nd PST slip yoke also. i said screw it & ordered a Mark Williams slip yoke, its definitely a stout piece. on a sidenote, i love how PST driveshafts are advertised to stand up to 1,000 hp, but their slip yokes twist with half that.

when i twisted the first one, i called PST & the guy said he had never saw one twist, but sent me a replacement at no cost to me, which was great. when i discovered the replacement was twisted, i didn't even waste my time contacting them for another junk piece.

i now have 2 more pieces hung on the wall that are casualties of a six speed car. lol

These reoccuring fatalities are why I only sell the PST Driveshafts these days with the upgraded forged slip yoke. I made the change earlier this year after several people had posted problems with the standard slip yoke. Bob
