72 Monte Carlo Posted June 29, 2022 Share Posted June 29, 2022 I have my stock 2.73 gears with a factory posi, but I want to find a type 3 carrier. I'm running taller tires in the rear and with the Big Block I'm installing in my 72, I want to lower the gear ratio. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted June 29, 2022 Share Posted June 29, 2022 I purchased a kit from eBay. Had the Detroit trutrac, new 3.31 gears and install kit. 1 Quote Link to comment Share on other sites More sharing options...
Scott S. Posted June 29, 2022 Share Posted June 29, 2022 Don't forget to get the correct pinion as well. Quote Link to comment Share on other sites More sharing options...
72 Monte Carlo Posted January 29, 2023 Author Share Posted January 29, 2023 I just got a nice OEM 69 3.31 ring and pinion gear set. Does anybody have a good used series 3 carrier? Quote Link to comment Share on other sites More sharing options...

72 Monte Carlo Posted January 30, 2023 Author Share Posted January 30, 2023 I'm hoping to find one that's OEM as it will be more economical. I'm on a tight budget. Quote Link to comment Share on other sites More sharing options...
Scott S. Posted January 30, 2023 Share Posted January 30, 2023 Finding an OEM will still cost $$$ these days. Might as well get the aftermarket unit. Like James mentioned, it'll be a stronger piece AND have a warranty. Quote Link to comment Share on other sites More sharing options...
420ponies Posted January 31, 2023 Share Posted January 31, 2023 Oh, Do I know tight budgets. You'll find one but, it's going to need new springs and clutch packs, bearings, ring gear bolts too. You can buy what you need from Ron and probably save money not piecing it out. You can also check with him to see if he does have a OEM unit . He's very good to learn what you need. Helped me a bunch, especially on the Yukon Carrier. 2 Quote Link to comment Share on other sites More sharing options...
FrankOC Posted January 31, 2023 Share Posted January 31, 2023 Search eBay for a seller Staticz2229 (Quick Performance Racing). I bought an Eaton True-trac, Richmond ring and pinion, and install kit for $675. Or, they also sell a new Eaton limited slip carrier only for $345. 4 Quote Link to comment Share on other sites More sharing options...
72 Monte Carlo Posted May 25, 2023 Author Share Posted May 25, 2023 I ended up buying a brand new series 3 Yukon posi and complete install kit from Staticz2229. I just need to finish installing the inner valve springs on my big block and finish the little bit of body work yet to do on it, and then primer, block and sand, primer, paint and clear coat. After that I'll be ready to install the posi, gears, etc. 5 Quote Link to comment Share on other sites More sharing options...
