Awd to 4wd conversion
 

Can an 08 GMC Yukon Denali be converted to a 4wd system like the tahoe.? What's involved and est cost?

No.
 

Between the hardware, electronics, computers, etc. etc. labor, etc. etc. custom fitting, etc. etc.

I'm going just say... no.

Even if you could do it, the cost would be more than the vehicle is worth.

If you want the selectable 4WD w/low range, I'd sell the one you have and buy the one you want.

I'm not kidding, you're looking at a HUGE money and time pit...

However if you do undertake it, take some photos for us :)

Thanks but it's not for me. A buddy was looking at a Denali. That was awd. I was wondering if it could be done. The deal has since fell thru.
