Piece of cake to replace, unless the bolts are rusted solid. Should be a couple of hours at the most. The rancho shoks are great if you do alot of off roading, or travel on rough roads. But most don't have the gas charge in them that really smooths the ride on the highway. Most guys on here reccommend the bilstiens for these trucks, I haven't experienced it for myself, but I believe that when i do them, I'll do bilstiens. jmo
