My shocks mostly all fit on fine, but on one I did have to just shave about 1/8- inch off of the outer rubber. Pretty simple deal.
The Monroe 37112 is an OE Spectrum shock - their top of the line, and when I called Monroe they said it crossed to the cheaper blue and yellow ones. The travel lengths are slightly different, but for as much as my jeep compresses the springs, I would buy them next time. I think the blue ones are not very good. My last set of them only lasted about 4 years. Monroe has a good spec. table on their website: http://www.monroe.com/downloads/install-instructions-guides/MonroeMountingLengthSpecifications.pdf
