Although they don't list their springs for the 5.0 XKR's, their 4.2 springs will obviously fit, and as they are 25% stiffer than the 4.2 XKR OE springs, they should be very close in rate to the OE 5.0 XKR springs (which are around 25% stiffer than the 4.2 XKR springs).

Does anyone have these on their 5.0 XKR? If so, how are they?

Thanks.
