I am running the terra grapplers! It's not a true 6" lift! I think it's 5.5" lift! I'm hitting the radius arms!
I'm going to try a small wheel spacer tonight and see if that clears it!
Lol this has been a nightmare so far just trying to see if it helps! I've waited and waited for promises that weren't kept! Would like to have my truck on the road looking right instead of Hal of it done! I'm lifted rolling stockers now and it looks terrible!
I'm trying to help you here, but your post make it so hard to follow what you really have.
You say you're rolling stockers, stock wheels and tires, is the way I take it, and your rubbing the radius arms. If that is the case you have some major issues.
If you have the stock wheels on with the 355/60 Terra Grappler, of course is going to rub the arms. You need to get a wheel with more of an offset, I don't advise you to put "small" spacers behind the wheel as it is hub centric.
Also rough county does not offer a "5.5 inch" spring, they have 1.5", 3", 4.5" and 6" Springs. So you really need to figure out what you have.
Furthermore, if you do indeed have 6" Springs and 4.5" lift shocks, you run the risk of damaging the shock.
