I should have some used 5100s coming my way soon, depending on your application I would recommend (sp) BDS because of their no fine print warranty. You break it, they replace it. Another brand to consider is Rock Krawler, 2.5 max travel kit (I believe). You can npair that kit with the bilstein shocks. The cool part about the RK kit is that if you ever decide to go bigger (54" claws on a low lift), all of their kits are "upgradeable" to the next lift level. I just had a friend put one on and loves it.
