REM and Surface Treatments

Dan Fahey · 10-15-2019, 02:07 PM

Looking at a new set new of gears.
Considering having them Rem and MicroBlue treatment

There is Cryo'ing gears for more strength.
Does that work with axles?
What is the over all benefit..?

If you get all this treatment was considering using less gear ratio.

These are things to do only when you have exhausted every other idea of ways to go fast. Total waste of money on an application like you are considering. I would bet whatever amount of money you care to wager that you would see absolutely no difference in ET.

I just finished installing a set of 9” REM polished Gleason gears.I don’t think the REM polish will help with performance as much as wear reduction.I also micro blued all the bearings.It certainly helped the rotating torque, but again I doubt I’ll see any performance advantage.The micro blue stuff will most likely help in reducing wear and oil temps depending on the parts that are coated.I wouldn’t change gear ratio because of the polish or coatings.

WOW looked up Tom's Differentials
He rebuilt my 12 Bolt differential decades ago.

REM finishing your gears does help reduce friction between the gear mesh. Getting your gears down 4 Ra surface finish still enables the teeth to still have enough roughness to hold an oil film. Based on what I could learn from the Microblue website, the surface coat is to encourage cover and retention properties of the oil but won't change the surface hardness. My first guess is that you would then be able to run a lighter weight oil in the diff, and thus be able to reduce the windage and churning losses associated with gears going through and slinging oil. Like any of these kinds of changes, the percentage gain is minimal, but I can not see it making the car slower. As another data point, Nascar ring and pinions are DLC coated these days and that combined with improved tooth geometry I am told yields 1-2 mph in an A to B comparison test on a Super Speedway depending on the ratio used. There are 42 different ratios for nascars...

Don't want to name names as I don't want to get them in trouble but I was told by one of the gear suppliers that it is a waste of time, that the gear basically polish themselves over a period of time. In that instance, I was ordering gears and was requesting the added surface treatment, why would he turn down the extra money if he thought it was worth it?

There is a member on this board can't recall his name,believe he ran a black 64? BB Mopar. He used to coat/treat RP gears,the cost was very reasonable with good results in terms of gear life and performance gains.He may have sold the company a few years back...gsa612

Jim Bailey is his name, Top fuel was his game.....He did sell the business years ago and moved to FLORIDA .
