Ordered 4.0" aluminum DSS Driveshaft

Going back to a high speed balanced driveshaft. My j&c used to
vibe pretty good above 120 and now their replacement they cut and fixed you can hear/feel it last time at the 8th mile. It's to short causing the rear seal to leak and likely hard on the trans bushing back there as well. More wasted money spent on them when they said they could fix it without going shorter.

So with the new trans going in, so is a 4" DSS aluminum piece. It's warrantied to over 1000TQ, said to have the same strength as a 3" chromoly. Critical shaft speed comes in at 177mph, so dyno days are safe again. It's nice to know the shop needs to know your setup to build a DS an then give you its limits.

Might help the old 60s to, my current shaft comes in at 28 pounds. He said this one should be around 16. He said it helps with shocking the tire as hard off the t-brake.

Any case, damn I hope this is my last DS for a while. I'll be stopping at their shop on Friday in NC on my drive to Ohio to swap it out.
