8 3/4 489 Recommendations

[chris belser]

Looking for help buying a new 8 3/4" 489 Center section. I am looking for a 3.91 or 3.73 gear set. I am wondering if Sure grip or True Trac is better. I am also wondering where the best place to buy it is. Moser? Quick Performance? Mancini Racing? any others? I appreciate the help.

I purchased one from an ebay builder. True trac, 489 case 3.23 gears with the larger yoke. Ended up bypassing the ebay deal and just talking to him straight on the phone. Older guy sounded like he knew his ****. This is the guy on ebay. https://www.ebay.com/itm/381107270971?hash=item58bbc3753b:g:OJEAAOSwxH1T6~Gr

He does it old school and when you get your receipt its hand written. I dig that. His store on ebay is called Mopar Madness.

**** I forgot to give you the website. Id just bypass ebay and their damn fees and dial direct. Also with a true trac you do not need a friction modifier. That's what he told me. Also do not forget to mention that you are installing green bearings. He will need to know that. I think he takes the pin out for that. If you are doing green bearings.

It sounds like you are pleased with your transaction and luckily didn't have any problems. His Facebook reviews are one star and all of the BBB reviews are one star.

I had 0 issues with the transaction. Talked to the guy over the phone which to me is the way I like to deal with people. He built it and I think it was 2 weeks before it was on the porch. Hopefully someone else will have the same luck as I did.

Wow.. I never looked at the reviews on BBB. Ouch doesn't look good for them. But like I said 0 issues for me. Someone is always going to have an issue. His ebay feedback is excellent. Perhaps do your deal on ebay if you are worried.
Here is the ebay feedback page... Totally different than the BBB page.
