Just curious what you think.
I need one with 1350 U-Joints and was looking at the 3.5" diameter 4130 Chromoly version with their trans yoke.

I have one in the heads up car. Solved an issue we had with to much driveshaft speed with the old shaft. Oh yeah the new one is carbon fiber

I have one of his Aluminum ones in mine..

Nice quality of course..




Chris..

I have the moly one as well. Its a nice piece for sure. Just keep in mind its a royal blue color when you get it.Get the MWilliams pinion yoke and Spicer u joint with it.
There's a reason why all the pro's use Mark Williams.Unsurpassed quality.

I have one of their "masterline" alum. shafts. I've used it about 5 years no problems, nice piece 1350 joints and yoke.

i got the steel with 1350 joints and both yokes in my high 10 sec car,been pounded on since 2000.it wasn't cheap,but after breaking a stock style front ujoint on the starting line it's a good peace of mind.

Ran a Mark Williams 4" super-lite GOLD Metal Matrix in my old car 6-7 years ago. High quality piece. I paid $1,000 for it back then. Hate to see what it cost today......

I got a MW non welded/glued alum 3.5" with 1350's, it is a nice shaft.

My car has an old Mark Williams CM unit. At 137 mph its at least as smooth as driving down the road in your Imperial doing about 40.

451Mopar, Mark Williams is just a short drive from where you are. Go up to Louisville and buy one. Ask for the shop tour and bring along some rags to wipe up the drool!

Dynotech is very good too, but being local to Mark Williams I wouldn't go shopping anywhere else.

I have one of their mild steel 4 inch shafts. Wanted to buy the 3.5 inch chrome molly and they told me I was too close to the critical speed to run a 3.5 inch shaft. My shaft is pretty long and I probably would have had the same issues as Al did.......

I bought it, but don't have time to pick it up, so had them ship it. My old stock driveshaft vibrated, even after having it balanced, and I just replaced the 8-3/4 rear with a Strange S60 with a spool, and the 1350 moly yoke from strange, so I needed a new driveshaft that was shorter, with 1350 U-Joints, and hope it does not vibrate.

You still have to get up to Mark Williams shop and get a tour. It's worth the drive. I came away wishing I had more money!

PS: Ever get to Bandimere? I'm wondering if Skip Peters is actively racing his '63 Corvette tube chassis split window. He's the way I got up to Williams.

Well, I guess living close has some perks, I already received the driveshaft, looks nice. I was racing King Street and Club Clash Top Street at bandimere until I broke the rocker stand on the heads (again.) My 60' times were not very good as I would launch pretty easy because the old '741 case 8-3/4 limited slip was starting to make bad noises. Nor that I have the S60 with a spool, and a bit more gear, 4.10:1 vs the old 3.91:1, I may be able to launch harder and get some traction.
