I have a similar thread on Modular Depot, but I just wanted to get some opinions since the MD thread is kind of losing people who were contributing to it. I would love to get my hands on some 4.10's, and I had the idea that gears were a plug-n-play kinda thing ... once they're in, you modify your speed-o gear accordingly, and you're good to go. The more I learn about this mod, the more I am realizing (being told) that you need to modify your tranny as well (mine's an auto). Is the JMOD the best way to go? Or are there other/easier/better alternatives out there? Suggestions welcome!
