Bump Stops for 94 4x4

[rrands1]

I am installing the OME lift on my 94 3.0 4x4, and i have a q - the rubber spacers in the middle of the rear coils (are they called the bump stops?) are very large - is there any need for them if I am doing mostly off-roading (in AZ), or is there any benefit to cutting them down?

Thanks!
