denali driveshaft

[denali2012]

Ive been doing some research on lifting my Denali and ive read that I will have to replace the driveshaft to prevent vibration issues. Who makes a good driveshaft for this situation? Anyone that has lifted a Denali, which driveshaft did you get?

How big of a lift are you going? Worst case find a local drivline shop and have one made.

either a 4" or 6" lift. Haven't decided yet. Would like to fit 35" tires on

Just to clarify, your truck is AWD, right?

I would get the lift on and have one custom made. We have local shop and prices arent too bad.
