Hi guy's, I have a stock rear end from a 52 F1 and would like to change the gears from 3.92 to 3.31. Will I have to replace the carrier also to make this change? Any info on this is appreciated. Thanks.

 

Randy's Worldwide at ringpinion.com would be my go to for info and parts.

 

Yes, carrier needs to be replaced.

 

You may also consider the common 9" replacement. It's a bolt in deal and parts are everywhere.

 

I checked Randy's and they have a gear set with a 3.31 that works with Spicer/ Dana 44 but, like ALBUQ F-1 mentioned, the carrier needs to be replaced to accommodate the 3.31...........was hoping just a gear change to keep cost down. Anyway, this rearend is a side project for me, I replaced it with a 9" a few years back when I did over my 49 F1
I like working on this stuff so I'll check out the $$ and see if it's worth a gear swap. Thanks for help
