first off most built rigs lean a lot.. there's also a gas tank on the right side (if he usually has it filled pretty full, that will make it a lot heavier and lean to the right). also having a welded rear plays a big role in that because it wants to preload the suspension. dont know what kinda of shocks it has but investing in ones that are more stiff will help him out. i doubt anythings wrong with your suspension...that is if you have an alpro setup and haven't taken any leafs out.. as far as shackle angle, unless he way overdid his shackle angle, then that should be fine. if he had made his own hybrid pack, that might be a different story, but that's not the case.
