The Super Suspension Kit I received from Laurel Mountain did not have any rubber pads to go between the axle pads and spring retainer plates.
That doesn't mean there aren't supposed to be any, but just that my replacement kit didn't have any. My opinion (based on all the off-road vehicles and spring kits I've swapped over the years) says they're not necessary and that you want a solid connection between the spring packs, axle and spring pack retainer plates. When the rubber pads wear out, it will cause noise and all sorts of unwanted 'movement' between the spring packs, U-bolts, and retainer plates, which could lead to loosening of the U-bolts and premature wear (with potential failure) of the components - not to mention, the axle hopping around will affect handling as well.
Just my opinion.
