Got a set of 12 bolt 4:10 gears, look like 4 series, with 9 teeth on the pinion and 37 on the ring. The pinion has the numbers 4092 9 37 USAP9 Y (heart shape with a flat bottom symbol) 1 X and the ring gear has 3092 37 9 USA Y then the heart symbol 1 S. The pinion is engraved on the side 66 and the ring gear has 66A engraved on it! Anyone know who makes these? I've seen the funny heart with a flat bottom symbol before but can't remember where! Any help would be appreciated. Thanks, Marc
:confused:

Probably not much help, but they are 4.11's. Does the symbol look anything like the one on this (http://www.usgear.com/us_strange.htm) page?

Not really. If you had a picture of a heart and just cut of the bottom so it was flat, that it what it looks like. I looked at motive, strange, richmond and precision gear, but cant find any match for the symbol or numbers. Thanks for the try though.

have you checked out YUKON gears? just a thought...

Just tried yukon, still no luck! Thanks though.

It might be a old zoom gear they usually have a PHT on the ring gear,also most companys make 4.10's these days so if it's a 4.11 it's gotta be an old gear.

Forgot about Zoom gears..

OK, any ideas on how to tell if these are truck or passenfer car gears?
