Two piece steel driveshaft

[BK_GrandMarquis]

Has any had any experience with the two piece steel driveshaft that Sean Highland makes? Expensive but looks interesting.

[BillyGman]

Waaay overpriced IMO. However, I must admit that I'm not quite sure of what the claimed advantage of a two piece shaft is anyway. That is, if there really is an advantage.

[Pantherman]

The advantage is that the two piece shaft has a much higher critcal speed--shorter cylinders vibrate at a higher frequency. To justify the cost, you must have a crying need to go really really fast.

I had a custom Carbon Fiber Driveshaft built for less than 1/2 the price of the SHM 2 piece Driveshaft. NO VIBRATIONS AT ANY SPEED + the CF weighs something like 12 lbs!

Care to share some more details on this?

I think MM.Net members love carbon fiber.

:wave: Yeah, yeah. Any new info?:wave:

I've done a bit of reading on this and would love to get one if it's been tried on a Panther. :D

PST's drive shaft's look to be more expensive than Dynotech's MMC, they list $790 for a Thunderbird/Lincoln driveshaft, which I presume would be close to the cost for a Marauder. The Mustang and Cobra shafts are less, but then they are shorter, no? The Impala SS shaft is $799. This is, of course, less than $ean Hyland.

Sorry for the delay in getting back to you BK-GrandMarquis & Martyo...I had to dig through all my MM stuff to find the info. I had PST (Precision Shaft Technologies) in Clearwater, Fla. build my Carbon Fiber Driveshaft. They build a lot of the "Bad Boy" 5.0 Mustang Driveshafts. I worked with Mark Veldhuis and he had me take a bunch of measurements and provide details on the front 'slip yoke' + the rear mounting arrangement. The shaft will run approximately $800.00. I called Mark and talked to him on Friday...I told him to expect some calls soon from MM owners. My 'prototype' is SWEET...weighs @12 Lbs and works great! You have to measure from the end of your transmission tailhousing (not the seal) to the rear mounting flange on the differential...mine was 60-3/8". The only problem we had in building mine was in getting the correct front 'slip yoke'. The Marauder's front slip yoke DOES NOT have splines for the first 2-3/8". Mark could only find a slip yoke with splines the entire length...so I had a local machine shop machine out the splines to the correct depth. Maybe 'The Dealer' could come to the rescue and procure Marauder specific front slip yokes.

I was just looking at the PST website too. Hmmmmm, guess I gotta get out and start taking some measurements. Joe, did you have to take out the driveshaft to take the measurements or will leaving it installed work?

Thanks for the info. :up:

[Joe Walsh]

I left the OEM driveshaft installed AND left the vehicle on the ground*...I did not want to jack up the car and have the rear suspension droop, which could have changed my measurement. The OEM driveshaft has a big round 'collar' at the front which makes it hard to measure to the transmission's tail housing..but you can use a straight edge/ruler to help.
* PITA to get under a MM while its on the ground...but thats when I first noticed the 'soda straw' OEM dual exhaust... Yikes! 2" pipes!! ...I called Kooks shortly after seeing that. My brother's CV has bigger OEM duals.
