US/Strange ring & pinion. Definitely 3.73:1 and made for a 4-series carrier.
G01-888373-4 41-11 B9
Search shows Summit has US Gear part # “01-888373-4”, indicates “Not Available”, and confirms -4 is the carrier series. I bought the complete Strange 12-bolt in early 1999, and I suspect “B9” is a date code for February 1999. My memory is fuzzy on the fact the rear came from the factory with a 3.73 in a 4-series carrier. I didn’t order it that way, just assumed a 3.73 would be installed in a 3-series.
This is confused in my failing memory. Back to 2002 when the TH400 was installed, and a new set of 4.11’s in the 12-bolt, there was some confusion. I thought I told Second Street it was a 3-series. When they opened the rear it was a 4-series, so they had to reorder the 4.11’s and charged me for return shipping on the wrong gears. Current Strange price for a 3.73 is $325. I’m looking for $150.
Still have the free items - pair of HAL/QA1 315# front springs, Two Summit 5-gallon fuel jugs.
