Default Identifying Chevy 14 Bolt Rear ratios

Could you guys tell me how to identify the gear ratio in a 14 bolt? I've heard it can be found on the ring gear but I'd like to know for sure. Thanx. NORM

can be found i nthe glove box off of the RPO codes if the sticker is still there. can be found by jacking up the rear and turning the driveshaft....counting revolutions and what not, and yes, it can also be founf on the ring gear. it'll have a number like GM 4444444 9 41 5 65 or something like that. the 41 and the 9 are important. 41/9 gives a ratio of 4.56 which is most likely what it has in it. it might be 4.10 though

Well, if you can read the ring gear #, you obviously have the cover off, so why not count the teeth on each gear and be 100% sure of what's in there? 45 ring teeth divided by 15 pinion teeth is a 3:1 ratio, etc. Easy math, no undetermined coefficient linear time-invariant differential equations needed [img]images/graemlins/grin.gif[/img]
