My Suburban originally had 3.73 gears.


Mr. Seymore, I would like to hear your input regarding the standard top mount carrier bearing (as seen in post #5 above) versus the heavier duty carrier bearing that mounts on the bottom of the trailing arm crossmember, as more commonly seen in C20 and up trucks.

I'm not a fan of using the light duty top mount carrier bearing with small diameter shafts in a higher horsepower/performance based truck. I have always used the HD carrier bearing and larger diameter shafts with virtually no issues. There is a thread in the 'Racing and High Performance' section, discussing the durability of the LD carrier bearing and shafts in a racing application.
