I have a friend with a 2001(i think) 1st gen 4x4 AC V6 that has over 210K mile on it and has been used a work truck form day one. Needless to say his rear springs are toast and have been for years. He wants to replace them and I would like some opinion on what would be the best bang for the buck to replace them. I think he should upgrade to the 3 spring 1 helper pack.
He is also considering an air bag but only after the spring are replaced.
Any and all info is greatly appreciated.
