Paul, do a search on here for Spidertrax, and commonly debated topic. As already noted, I would recommend them over something only sold on eBay. They are $100 a pair for new from Quadratec.com and several other retailers, but with a little patience you can score a set on Clist or jeepforum or even eBay for @$50-75. I paid $70 for mine shipped from a guy on jeepforum.com
Mine are the 1.25" and they are plenty. 1.5" would probably be perfect, but point is, you don't want or need a full 2", that will stick too far I can tell you. I also have Ravines so I'm giving you a true apples to apples opinion. SuperWade2 posted pics of his after he put on the spidertrax and you'll see that will be enough. He does not have Ravines, so I don't know what his offset is. Hornbrod has spacers and Ravines, but I don't know if his are spidertrax. :thumbsup:
