What does he plan to do with the truck? If he is going to take it off road, he will go thru front end part no matter what kit he puts on it. I have had my Dick Cepek on my 95 Tahoe for almost 5 years now. Tie rods are a once a year deal. My buddy procomp on his 95 Z71 is the same. We both run the trucks off road.
I am not doing a SAS on my Tahoe. If I knew I would have to replace front end parts like I have, I would have dropped the extra 1000 in a SAS in the first place.
