I'm looking for any assistance on recommendations for coil spring and shock replacement. I'm trying to bring the vehicle back to its original ride height, but I'm not sure what the factory original spring load rate is on my springs. There seems to be many front and rear spring options depending on load rating and constant or variable types. Can anyone provide me with the original coil spring specifications for the front and rear of a 1987 442? Also, I'm thinking about replacing the shocks with something better than what the factory gave it. Currently, I have the air adjustable rear shocks and the front shocks are the standard OEM. I seen a set of coil spring assisted shocks from Monroe, but I'm not sure if that will make the suspension too stiff. Any recommendations based on ride experience?
