Driveshaft size

I found a 1 pc at an Auto salvage yard, will it fit in my trunk?

Should I look into getting it balanced for 4.10s or will it be okay?

90% highly doubt it.

question:
do mark 8's have steel or alluminum driveshafts?

Posted by: ONEBADMK8

Aluminum, junk design too.

Highly doubt what?

That it will fit in the trunk.

And aftermarket driveshafts seem to be the only way to go with the big gears.

Where can I go about getting one? Not worth my while trying to get the 1pc balanced?

Not worth all the agg at all. Heres the real deal.

Tell them Geno sent you and they will know just what you need.

What will one of those run me?

Posted by: ONEBADMK8

Like $520.00 shipped I think. Call him up.

Ive tried both a stock one piece, and an MMX driveshaft, and nothing comes close to the MMX. I know others have had good luck with the 93 one piece unit, but not me.

I have em in all 3 of my VIII's
MMX is worth every penny.

Posted by: Dern Humpus

I dont have 5,000 pennies to spend on a driveshaft, so I am going to try my luck with the 93. Thanks for all of the input though. If it doesnt work out for me I know where to go.

$520.00 for a drive shaft? Couldn't you get a custom one built for less than that? That seems very pricey.

If you did you would still be 47000 pennies short.

There is a reason. the VIII driveshaft is VERY long, and a standard aluminum shaft is too flimsy to allow high RPMs inherent with a gear'd VIII. when you get a stock shaft up to speed it will actually start spinning offof it's centerline causing one hell of a vibration. It can be bad enough to break rearends, and I have seen them break tranny extension housings.

the MMx shaft is not only LIGHT, but it's stiff enough to NOT go nuts and vibrate at high speeds, and rugged enough to transmit the torque needed to drag the whale off the line and not break.

worth every penny.

The 93 one piece is definately worth a try as long as the junkyard isn't charging out the ass for it.

From what I've read, the MN12 driveshafts are just as bad. The 93 one-piece is in demand with the MN12 guys as well. They have the same vibration troubles that we get...

Well this junkyard happens to be charging $75 for it

That's a pretty good price; as long as it is the driveshaft specifically from a 93' and not a driveshaft that happens to fit 93-98 years.

evilally has a VERY good point. The 2 piece shaft LOOKS like a one piece except for a 1/2" grove at the joint at the rear of the shaft where the 2 ends are pressed together. Make sure that your new unit does'nt have this.

Side note, thats the MMX shaft I put in the 98 sitting next to it.
