I'm building a 9" traction-lok for my '68 convert. It will be a evening and weekend driver. I found that the ring gear for the 3:50's I was going to use had a broken tooth. I need a new gear-set. I've been told that OEM gears make less noise. Is that the case? Does anybody have any recommendations for after-
market? or are they all good?

I have a '92 AOD and a '89 5.0 that will be going in next winter. Any recommendations for ratios?

Thanks

I'm running a Motive Gear set in my 9" that I got from NationalDrivetrain.com and it's smooth as silk /forums/images/icons/wink.gif. I think I paid $230 including shipping with an overhaul kit.

Oh, reguarding the ratio, I'd opt for something in the 3.70 range. The latemodel guys all run 3.73's with the AOD tranny. The 3.50's are just a little much for the C4, but liveable. The AOD will make a significantly taller ratio acceptable on the freeway. Just as soon as I blow up this C4 I'm gettin' an AOD...

I honestly can't give you an answer on the noise issue, try calling Currie or Randy's ring and pinion on that. I know from reading in the 5.0 magazine, they recomend 3:73 or 4:10's with the AOD for best results. The AOD has a very high 1st gear. This puts them on par with 5 speed cars with 3:27 to 3:55 gears.

Ive been told the OEM gears are far superior to the aftermark ones. The source was reliable
