Also changing to 4.10 gears this winter

[Jagdpanzer]

Like some of you other guys I'm also considering changing from stock to 4.10 gears this winter. Seems like there are several possible sources for 4.10 ring and pinion sets these days. Not sure how they all rate though. I don’t want to end up with a howler just to save a few pennies. Any opinions out there on how aftermarket suppliers like Precision, Yukon and Richmond stack up against OEM gears from Dana in terms of quality, noise and strength? It is my understanding the Dana 44 HD differential in the ZR-1 has a larger diameter pinion shaft than the Dana 44s found in other applications so not all gear sets you see offered will work in our model Dana 44. I haven’t yet quite figured out how best to go about ordering so I’m sure to get the right ones. Does anybody know the Dana part number for the 4.10 ring & pinion set we should be using? Also, I’ve heard where some have used Viper gear sets. What is so special about these? and can you order them online anywhere? Any advice from you more experienced forum members is very much appreciated. I'm from just outside of Washington, DC in NoVA and it’s been a challenge finding a competent shop able to do the set up work. Hope you are in better shape where you are located.
