How much spline is left in the slip yoke??? If it's less than half...which it probably is...you'll need to hit the junk yards for a longer model, and cut/weld it to size. Your shorter one can be sent to me!!!

I put a 6 inch lift on a blazer and have had no front drive shaft issues at all. I wheel the heck out of it and not one problem. You could also look into dropping your crossmember that could be enough.

Same here..4" lift should be fine with stock drive shaft.With a 6" lift the stock driveshaft should work,but it may not extend out that much.Having the stock one lengthened shouldn't cost that much.I don't know what models interchange that have a longer front driveshaft..

well looks like im going to cut it and weld it up at work and have the machine shop turn it back down.

I would still take it to a driveline shop and have it balanced. It doesn't take much to cause a vibration, which at the very least is hard on seals/bearings.

I had rear driveshaft shortened, balanced and new U-joints installed and it was only $115.00. They sprayed some kind if stuff looks like a bunch of bumps on it to get it balanced right. They also welded wieghts on(or kept original) to balance.
