With 35"s, 4.88s are going to be your best bet I would think. I am going to assume that you are on stock axles (30f/44r) yes. might want to look into some protection for your 30 as well, maybe some c-gussets and/or sleeve or truss. Yes, with 35"s, these are not a must, but depending on how you are wheelin', they are just some added insurance.
