Often overlooked, but essential.

Upper Spring cushions are used by vehicle manufacturers to isolate vibration and road noise from being transmitted to the chassis. Many aftermarket Mustang-II IFS kits don't include these cushions, but they are essential if you are going to drive your vehicle much. Place the cushion on the top of the spring, put some masking tape in a couple places to hold it in position while you install it.

Make sure cup size on top of spring will accommodate cushio

Product was good. Only problem is if you have a front stub which was manufactured by Fatman the spring cushions will not fit in the spring cup. I ended up not using the product even after modifying the cushions, still would not fit. You should mention fit requirements in your catalog.

I am converting a replica XK120 into an EV. Front suspension was from a Mustang II but the springs were too big for the reduced weight of the car. These coilovers are a good alternative.
