To all you guys running coils but not coilovers. I am putting one tons on my dodge 1500. i dont like how big in diameter the dodge coils are. and i need to find some coils for my rear four link. what are you running? Many have suggested the bronco/f100/f150 coils. any one have the measurements on these? i see that they are avl in up to 9" lift. what i need to know is: If they are stock or lift springs. how much advertised lift, Compressed lenght, inside diameter, outside diameter, and if they are flat top and bottom.. looks like they are flat top but not bottom. and who's are the best, Sky jacker?
