I have a running thread already that discusses this topic, but the title is different and the thread got off the original topic.

I recently located and acquired a brand new 5.43 gear set for the H110 axle in my 1950 4100. I purchased it from Inter-Continental Gear and Brake out of Grand Prairie, TX. The description and part number on the box reads as follows:

"H110 Crown/Pinion Ratio 5.43 27 spline GM2352908"

Now - I have no earthly idea where the "27 spline" part comes from as the pinion only has 10 splines on it and so do the axles. All I know is that this gear fit in my axle. The gear set manufacturer is Cobra Gear. The set cost me $395 + shipping.

I have plenty of pictures which I will post up later as soon as I get time to upload them somewhere that will host them.

I have not yet finished the installation. Still waiting on a few gaskets and seals to come in. I'll be sure to update the thread with my road test results. I am hoping to be able to achieve 55mph now!


1950 4100 - unrestored and driven weekly for almost no reason at all.
