I have been looking for a while and finnaly found some, and for a really good price. They are made by superior axle and gear and clame to be 35% stronger than stock, they are actually cheaper than i was payin at the junkyard when i snapped a stock one. Summit sells them and they are 91 dollars a piece and with shipping still under 200 for a pair of them the part number is sag-6013 i know it says there not for our trucks but i got that part number from somewhere else and they are currently installed in my truck so they do fit. Btw i have a 00 silverado 1/2ton 2wd.

I used a set of them with my 8.5" and a set by Yukon. All four are twisted and it happened the first time out at the track on both sets.
