I'll adding a 470hp 383 to vette this summer, and want to replace the U-joints with heavy duty ones also. I've been looking in Jeg's, Summit, corvette catalogs, supporting vendor's websites, but I can find anyone who carries heavy duty U-joints that will hold up with this motor. Any ideas :confused:

Ryan77,

Spicer u-joints came on the car originally, they are generally available at truck supply houses.

I just put Spicers in mine... about 450-460HP... after blowing a half shaft this summer...

If you stick any will break.. If your planning on big time racing go with Tom's Diffs..

My local parts store (Robbins) carries the Spicer line.
Call around, you might find 'em closer than you think.

Call Inland empire. They know drivelines and can tell you what to use.

Spicer got bought out by TRW, and when I ordered solid u-joints from TRW, I got federal mogul u-joints. (They screwed up so i got 180 dollars worth of u-joints for 79 dollars :) )

Thanks for all the replies. I'll call a few of my local parts stores in the morning. I won't be doing much racing on a track with this car, since the closest track to my house is in the next state :( , I'll probably only go to the track once, just to find what it can do. I will be rebuilding the whole drivetrain late next year with a ROD 6 speed, 3.73's, and beefing up the rest of the drivetrain. The car will probably never see slicks either, the most it will see is 17"x8" wheels with BF Goodrich G-force tires, so I shouldn't have too many problems :cheers:

Im using solid non-greasable joints by Brute Force. Got em at Auto Zone for $12 a piece. Over a year now and no problems. I greased them up good with Mobil1 synth grease before installing them. The solid non- greasable ones do not have the hollow channels to carry grease from the zerk. This solid design is said to make them stronger. Whatever joints you decide, make sure to pull all the caps and verify that all the needle bearing are there. More than once I have found missing needle bearings in brand new joints.

Ryan down here we have FleetPride truckpart stores,maybe they're up there too? They carry the Spicer line for about $18 each. These are HD and come pregreased. They have a compression type cap that will snap in place once installed. If you can't find them in MA let me know and I'll check here.

O'Reilly Auto Parts have Heavy Duty solid u-joints.

Precision U Joints, which is a commonly distributed brand in most conventional jobber networks (maybe not nationals such as AutoZone, Advance Auto, etc) has HD joints in their catalogue. Like somebody else mentioned, they're not drilled for grease fittings in the middle of the joint.
