Mine is a pickup that I did up when I was in high school, 4" over 33's will work fine but I abuse my stuff a lil bit, therfore my tires would hit. I ran the dual stabilzer but I don't think it really did shit when your running 35's, so I took it back off. Those old square body chevy's ride stiff when you get any lift in them, and it seems they just kinda have a bounciness to them and kinda wander a lil, just my experience.
Here is a pic of it after I had re did it in 1997
At the time I had some 35 x 14.5 x 15 Super Swamper Boggers under it with just a 6" skyjacker lift and the fronts would hit.
That truck since then has had in order 2 different 350's, a 400, another 350, and back to a stock 400.
A different set of 1/2 ton axles, a 3/4 ton set of axles, and now the final set of 1/2 ton axles.
3 different 700r4 trannies, 1 TH 350 tranny, now it has none.........
The truck just sits it my Dads barn with no box, no tranny or transfer case and is not running :sad:
It now has 7" of total lift with some 35 x 12.5 x 15 wild coutry tires on it, I took the facctory Rallye wheels and had them cut on a big lathe actually 8 rims in total, and re welded the two deep halves together to make them 15 x 12 rims, that helped give the tires some bulk, the next set I do will be 15 x 14.
