Curious, if any Mopar racers would be interested in a 5.00 rear gear sets?????? 489 case only!

Re: Attn. Mopar Stocker racers?????
 

I would if it were a Pro Gear.

I would?

Re: Attn. Mopar Stocker racers?????
 

I would be interested in a couple of sets

I would be interested in a pro gear.

I have several more sets sold if we can get them made.
Thanks

Re: Attn. Mopar Stocker racers?????
 

Yes, we would take a set if they were Pro- Gears, please confrim the rear pinion diameter if made, let us know Terry Dye Brighton Michigan

Re: Attn. Mopar Stocker racers?????
 

why the 489 case?

Re: Attn. Mopar Stocker racers?????
 

that's the strongest of the castings

Re: Attn. Mopar Stocker racers?????
 

I heard over the years that 742 was the preffered one because of the larger pinion bearings,thats also the one that had a pro gear ava.in the days,but not anymore!

Re: Attn. Mopar Stocker racers?????
 

I broke a bearing cap on my 489 case. Destroyed the ring and pinion. Had to take the trans out to check the over running clutch.
It has not happend on the 742.

I'm interested getting ready freshen and order replacement set of 5.13 gears 5.0 would be just right. What is the ETA and who are we ordering them from.
Best Regards,
Mike

Re: Attn. Mopar Stocker racers?????
 

I would definitely be interested in a couple sets of 5.00 pro gears but for a 742 case only. I have run the 742 case for over 35 years ... I think the straight pinion is much stronger than the tapered ... Jim Nichols did the same thing John Dinkle did to his 489 case, busted the bearing caps off both sides. I have broken at least 4 ring and pinion sets in a 742 case and I am still using the same case ...

Re: Attn. Mopar Stocker racers?????
 

I also broke a 489 cap which took out the ring ,pinion and transmission on the class final at Indy. I have seen the new 489 case's and they apear to be much stronger than the older ones.
Thanks

Re: Attn. Mopar Stocker racers?????
 

I would be interested in two sets pro gear and 489 case only. The new 489 cases comes ready out-of-the-box, no need for billet caps, and easier to assemble.
Thanks

Jim,
What is the status of these gear sets being made? thanks

Re: Attn. Mopar Stocker racers?????
 

I will take one set, but would prefer the 742 case. I have knocked the caps off too many 489 housings. But I will take the 489 if that is what it takes to get it done.

Re: Attn. Mopar Stocker racers?????
 

Thanks everyone for all the input and replies, not to dicourage any of you but they will not be making any of the Pro gear sets, at the current time we are working on getting sets built for the 742 case only at this time. i was told there will be about a 4-5 month duration to get these built! i was told it's a tooling thing. we hope to have the first 50 sets availible about April. thanks again,

Hey Jim ( and other Racers ), We can Cryogenic Process and/or Rem Finish your gear sets. I wouldn't even worry if they weren't Pro Gears. I can't get Pro Gears for my car. ( 742 case 4.56 ). Ask # 1 qualifier at most Div.3 races - Chuck Beach - if he's broken any gears lately! Or better yet, what changes he made to his car that increased his performance this past year. Or ask, Michael Beard, Jeff Day, Scott Macy, John Dinkle, Phil Baldichino, Cheatin' Charlie Downing, to name a few, what they think. You can expect 2 to 3 times the gear life with quieter, better performance. It's cheap insurance.Thanks, Jim Bailey

Re: Attn. Mopar Stocker racers?????
 

How much of that is from the cryo treatment, and how much is from the rem finishing?

Re: Attn. Mopar Stocker racers?????
 

That's a really good question. And the answer is % wise, I don't know. I ran Cryo'd only ring and pinions before I started Rem finishing them. Done correctly, (and I can't stress this enough ), and in a quality machine. I think the Cryo'ing adds more to the life of the gear than the Rem Finishing. I think the Rem Finishing adds more to the performance of the gear set. Think of it in terms of the Cryogenic Process treating the gear from the inside out, while the Rem Finish removes any surface imperfections and/or stresses. One thing I've noticed. After the Rem Finishing, any machining imperfections from the manufacturing of the gear set show up like a zit on your nose. This allows you to hand polish, with a cartrage roll in most cases, the "bad spots". It's my feeling that these imperfections gone un noticed cause many of the gear failures that we see today. If you're freshing up your rear this winter, I suggest you try it. It's cheap insurance. And I pay contengencies.
The hardest thing for me to convince racers is, Cryogenic Processing has improved many times over in the past couple years. They say, I tried that, it didn't work. NO, if you haven't tried it in the past year or two you haven't tried it. Cryogenic Processing, done correctly, is now done in expensive computerized machines. Gone are the days of 5 gal buckets with dry ice, and/or beer coolers.
Ask anybody doing Cryo a couple simple questions. How old is your machine? What type of insulation is used in your machine? (styroform breaks down with age ) And do you temper your parts after cryoing them? This is an important part of Cryogenic Processing. Thanks for asking. JB.

Re: Attn. Mopar Stocker racers?????
 

Bailey "FINISHED" my ring & pinion (4.86 Richmond set). I'll let y'all know if this one ever gives out. The last ring & pinion I had in the car only lasted 1 year (which granted, is several hundred runs for me).

On the performance end of things, at the beginning of the season, I ran 6.88 @ 98 mph at Piedmont in mineshaft conditions. I'll have to look it up, but I think it was a 1.41-1.42 range 60'. That was all with the standard 4.86.

I just got back from another mineshaft day at Piedmont - pretty similar conditions. With the FINISHED gears, I ran my career best with my H/CM Volare, 6.757 @ 99.33 mph, with a 1.376 60'. :D :eek: :cool: :D Thanks Jim! (and Sloan Racing Engines!)

Jim i sent you a PM!

Re: Attn. Mopar Stocker racers?????
 

Should parts be cryo'd then rem finished, or rem finished then cryo'd?

Re: Attn. Mopar Stocker racers?????
 

Cryogenic Process followed by Rem Finishing. Thanks, JB.

Re: Attn. Mopar Stocker racers?????
 

Jim,
What is the status of this 5.00 gear?

Re: Attn. Mopar Stocker racers?????
 

Hey Jim,
what is the status on this 5.00 gear sets? thanks

Re: Attn. Mopar Stocker racers?????
 

I would be interested in a couple sets if 742. I also wish I could get a 4.7 to 4.75 ratio. Thanks
