03 2500LD ring gear size?


Recommended Posts

Hey all. New to this forum. Ive been searching around for a while and ive seen 4 different answers for my question. I have a 2003 silverado 2500LD that i sled pull with. Looking for a rear diff cover/new rear gear sets. Truck has the g80 rpo code and is an 8 bolt hub, but i cant seem to find a solid answer. Do i have a 9.5", 10.5" or 11.5" ring gear? Unfortunatly i dont have the rpo code sticker as i was stupid and threw it out when i gutted the interior.

2500 non HD (8600 GVWR) have the 9.5" semi float 14 bolt rear axle.  

 

10.5" and 11.5" would be in the 2500HD (9200 GVWR) and 3500.
