shocks

[05AZgmc]

any one kno if bilstien makes the 5150s(stock replacement option with resivor) to fit an 4wd 05 or 06 gmc seirra? seems liek they wouldnt cause all the pics i see of the shocks just have liek an i bolt set up, and my truck has the top mount that needs a little threaded rod to go through looks like, and the bottom is some weird thing i never seen before. if no info on that, what are some good shock options, not nessarly all off road, but just all around. its gettin a little like a boat on the road and i want it a little stiffer and less bouncy, i bet mine are shot. how about some bilstien oe replacements? do they make the nickle plated ones for my trucks, pics or info would be great. lots of questions tonite lol. got some money coming to me from a bonus from work, and want to spend it on somthing good instead of waste it onfast food and cigarettes. thanks
