yup custom springs as well as custom boggie arms, its not as bad as you might think. 5 ton parts are WAY huge and the only way that would work would be if you had the long spread 5 ton suspension and use the whole thing. thats a lot of added weight for nothing. if some one is interested in any of the custom parts on my truck just send a pm and i can hook you up. Spring,links,rims,tire, any or all.
