Mikronite vs REM

[Hacksaw]

Curious: What's slightly different on the set -up involving treated gears?

[John Dinkel]

I used Synthetic 75-90 Mobil 1 on mine. The gears were Chryo and REM finished.

Since the surface is flatter and finer you can set the Ring and Pinion with a tighter clearance.
There is less friction, less heat and part expansion.
Slipperier tighter touch should provide a better feel and response time.

Dan, the best results we had were with the Pinion Depth slightly deeper than recommended, into the ring gear, then making sure the backlash was set a the tightest spot you can find rotating the ring gear. "IF" then the backlash seemed too lose the rest of the rotation, we didn't worry about it. The only time we got into trouble was with the set up being too tight. My guess is the Cryo'd and Rem'd gear sets don't "wear in". For lube we always ran 75/90 synth. keeping in mind that we always ran max capacity. None of that 1/2 to 1 quart B.S. Your ring and Pinion is a very high load area in your race car that requires lube at all times. Not saying this is right, but it worked for me ... hope it helps.

I have no experience with setting up gears but was carrying on a conversation with a guy that set up diffs and trans for Nascar and circle track guys. He said one of the benefits of "treated" gears vs. a non treated ring and pinion the set up was the treated gears pretty well stays constant. He said on a non treated diff you need to keep a frequent checks to insure the clearances stayed where they should be.

YEAH it does actually. Mine is filled.
The SS uses a 8.5 Rear 10 Bolt which is a strong rear.
Full Stock figure you would need the 12 bolt 8 3/4 rear.
Might add a heater to keep it warm.

Who are some of the vendors you all have had good luck with treating ring and pinions?
Thanks,
Bill

I used Performance Engineering & Manufacturing.
Charged $164.00 total to do both Cryo & REM treatments.
Turn around time once they received the ring & pinion was 14 days.
Contact Randy to get a CN number for any parts you send to their plant.
