Vehicle Speed Sensor - ZR-1 Net Registry Forums

In preparing to put in 4:10s this winter, I came across some tech notes about changing the speed sensor in the transmission. What exactly are the parts needed, and where is the place to get them?

I had to do this when I bought mine. You basically need a new VSS drive gear (little plastic thing) this goes inside where the speedo connector attaches on the gearbox.

It's a relatively small job in itself, the difficulty comes from the fact that you need to take the exhaust off to get access and sometimes disconnect the drive shaft. Not an easy job if you dont have a good way to get underneath.

I didn't and took it to a dealer who ripped me of completely.

I'm also considering changing from stock 3.45s to 4.10s 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 donâ€™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 havenâ€™t yet quite figured out how best to go about ordering so Iâ€™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, Iâ€™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 itâ€™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.
