14 Bolt full floater 3.21 ring and pinion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anybody know what a new set of 3.21 ratio ring and pinion for a full floater 14 bolt is worth these days? I hear they are very rare to find?

Thanks.

Brand new set? about 3-400, used 200

If you've got a 4wd and looking to match the gears, the only thing you will find is a Dodge ratio in a dana44. Those are hard to find also. Makes a nice ratio for a diesel though

But do you know where to find a set for the 14 Bolt? 3.21?

give randys ring and pinion a shot, seems like a pretty good source, heard the name pop up on multiple occasions.

KW,
do you know if its Ok to mix 3.21 in the rear with 3.23 up front? Are they close enough to not cause a problem?

Thanks.

That close , no problem. I've built diffs for the toyota crowd that uses a toyota 5.29s in the rear and I the closest I can match with the Dana 44 front is 5.38

Yeah, the .02 difference between 3.21 to 3.23 wont make a dofference

The only thing you'll find new is 3.42. EastCoastGear has OE for $330. Or if you call them they have aftermarket for 2 something.
