For that price I'd buy Currie, Solid, Dynatrac or TeraFelx D60's. Just priced out front and rear for a JK (brackets pre-done), $11 000 - 14 000, with detroit in the rear. Bit more with selectables, and price depends on company. All 4 company's work with the stock ABS, ESP, Traction sensors and can run 4.10, 4.88, 5.13, 5.38 gearing beefier bearings, and 35 spline. I think it may have been Solid (could be wrong) offered an upgraded brake package too - Brembo 6 piston calipers designed for heavy weight loading, still works with the ABS system. The TF and Currie look like they're the beefiest at this point, and the Currie even has a AR400 steel skid plate (stuff they make loader buckets and stuff out of).
