You learn something new every day
I was looking at doing a swap to an 8.8 axle because I always assumed I had the 7.5 but just looking around on info on axles I saw a chart for axle codes and I went and checked and it was R7 and apparently that's a 8.8 w/ 4.10's.
Why would I have an 8.8? I have a 3.0 edge 2wd. Also is this the 28 spline or 31 spline axle? And it's an LS so does that mean its a limited slip?
