I am selling a brand new set of rear differential side gears and spider gears for a ford 9.75 differential. The set includes the pinion shaft and retaining bolt as well. They are 34 spline and made for standard/open diffs. They will not work for limited slip diffs unless you change out your clutch packs as well. I bought these for my truck but they were the wrong ones so I am just trying to recoup some of the money I spent on them. They are brand new, never installed and still in the original box/shrink wrap packaging. 1 gear was opened to check fitment and then put back. Feel free to email/text me with any questions you may have. Price is O.B.O. Thanks for looking.
