How tight should they be w/o damaging caps?
Supershafts, I don't know. I had them make me a 3 1/2" aluminum drive shaft with 1350 yokes and that's the way they came. No fittings. Maybe I better ask them.
Thank you, Run, I'll pull the drive shaft over the winter and take it back to Inland for them to tune up the u joints just as a safety measure. I don't want to beak a expensive drive shaft. They are only a few mles from me.
I'm only a little over 700hp and do maybe 100 runs a year. Looks like I got a few more years life left. Thanks.Depending on hp, and runs you shouldn't have to change them for probably 6 years if your at say 800hp and 200+ runs a year, then at that time check them and look for any stiffness or overly loose
as one buddy said to me when I asked about no grease zerk joints... when was the last time you actually crawled under the car and greased them anyway?
