I just recieved rear coil over upgrades and a 3 link kit I recieved silvercolored aluminum shocks and they are set up for 1 7/8 coils. FFR sent 2 1/4 springs which are to big for the 1 7/8 retainers now Im questioning the shocks as most rear shock pictures I find are gold anodized forlive axle.Do you guys think these silver jobs are for IRS rears are the dampening rates the same? need your guys input before I tackle the FFR phonecall Thanks
