[CJM72]

I'm nearing the end of my LQ9 swap with 4l65e transmission. At the moment, my Blazer has a 3.08 gear ratio and 33" tires. Pretty much a recipe for making overdrive sluggish at best. I had always assumed I'd end up changing the gears to 3.73 or something similar in the future. I have an opportunity to buy a complete set of 3.73 diffs from rippen. Is it better to just swap the axles out entirely? Re-gearing what I have would probably be left to a driveline shop and cost $2k or more I'm guessing. However, I'm concerned I'd basically need to rebuild the 3.73 axles as well and end up in the same cost range by the time I'm done.

What's the collective wisfom of the group? Regear what I have or swap both axles out? Thanks.
