This axle in my truck?

[Wally81k5]

I recently found a 12 bolt in a junk pile. I was intrested because i have 3.08's. Soo can anyone tell me if i can pop this carrier into my housing to lower my gears. its a 12 bolt like mine, and is stamped 3817778 11-41 G.M. 60 i think it is 3.73. it came off an old like 50's truck but may not be the original for that truck. Also, how wide is the stock 12 bolt in a blazer? and where are you measuring from? Thanks for your help!

[/ QUOTE ] Yes, It is a 3.73. The 11 is the number of teeth on the pinion gear and the 41 is the number of teeth on the ring gear. /forums/images/graemlins/usaflag.gif

Cool 3.73 is okay for me.


So does anyone know if this carrier will work? I found out its actually from a 72 chev. 2wd.

Also still wondering about those measurements.

thank guys!

I dont have measurements but last I looked into this swap just pull the 6 lug shafts on your axle and swap them into this scrap pile axle and call it good. you now have a 4wd 12bolt with the 6lug pattern.
