So, my truck came stock with 3.21’s. I bought what I thought was a 3.92 antispin rear axle assembly and a front unit to swap out. I paid someone to swap the rear and I did a burnout afterwards and still had one wheel peel. I super curious now to even know if I bought a 3.92 antispin. The sticker is messed up. So how can I tell if it’s a 3.92 with antispin?
