Need some help with aftermarket driveshaft fitment - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a 3.5" aluminum driveshaft from the Driveshaft Shop. They provide a 1 pager with torque specs and a dimension for the CV joint portion at the back of the tranny. The spec says dimension should be 3.25"-3.75" (and they state "running it outside this spec will void the warranty"). Mine measured out at 3.13" indicating too long of a driveshaft. This was ordered for a M6 tranny.

Because of the extra length I had to mallet the heck out of the diff side flange of the driveshaft (not on the universal joint). Anyone that has installed an aluminum DS, did your go up by hand (without a mallet)?

I installed it with car on jack stands, wheels hanging. Wheels hanging I would think shouldn't matter since the rear housing is bolted to the chassis. Thoughts on this? I may head back out and load the suspension, but I don't anticipate any change.

I am wondering if I got DS for an auto tranny inadvertently.

Looking ror opinions or wxperience here. I reached out to the vendor I bought the DS thru.

Might not be much help (bec mine is an older model and for a M6 V6) but mine went on by hand after slipping the blue flange on the diff with the "pin" in. No mallet needed but I used my hand to make the end of the DS meet the trans adapter, it measured out to be 3 5/8.

Edit: after rereading your post, try compressing the driveshaft on the sides of the cv joint.

Mine installed easily by hand with the car on jack stands. Call DSS.

I'd call DSS directly -- they have excellent customer service.

I installed their Carbon Fiber version and had no issues. DSS will be able to tell you for certain what you have.

Here is a pic of mine installed and checked:

I talked to them today. They said on occasion they have DS's that are too long for whatever reason. If I have the right DS then it seems that my car's parts just stacked up too tight from a tolerance analysis respective (meaning that when you look at all the dimensions related to locating the engine, tranny, rearend, thicknesses of flanges, etc that it created a shorter length from tranny output flange to rearend input flange).

Anywhoo... They said that they will mill down the tranny adapter that came with their DDin order to get me into the proper dimensional range.

Thanks for everyone's input.

Glad to hear that. Like above, they have great CS. Didn't even buy my DSS DS from them directly (but used) and they helped a ton.

I had to do the same thing with my DS, I was about 1/16" below the minimum distance, but since we are a machine shop, they said it was OK for me to just machine the trans adapter myself. I just switched to the carbon fiber version, it was the same way, as it is the car itself that causes the problem, as they stated to you.
