Yea time kills batteries, and so does negative teen temps lol. Those 17's? I have the 5 spoke 20's off of a newer Tahoe for mine. Originally started polishing them but lost motivation on that. Going to dip them silver and call it a day lol. I have the old ugly 16's on mine currently.
Yours a Z55 autoride truck? Mine had that and it was bypassed and I think they used crap struts which is why it rides and rattles so bad. That's why I was looking at the 5100's. I also wanted to lift mine just a couple inches so I could stick a 33" under it. Pretty cheap to do it I guess. I had a bunch of **** I wanted to do but I kinda of hate the thing cause of all the rattles it has.
