I have a 1981 camaro with a 454 iron block and heads (gen 6 crate) with A/C and stock control arms and would like to convert to coil over. What spring rate do you recommend and can this kit be installed on factory control arms?

Hi William, The part number you are looking for is the one you were viewing, 7081cok-2a550 is the part number you will need. Thank you. 

Did you find what you were looking for?
