Ring and Pinion strength

[Red Rover]

I am in Australia looking at upgrading to a stronger front diff. Although mine is auto and have not yet broken one with front detroit and rear elec locker, it's probably a matter of time. What do you guys think about the cyro treat diff ring and pinions. I run 285 x 16's most of the time and 35 claws to go a bit harder. Is it worth going to the treated 4.8's or not, or will i break centres. I know at some point I will, but I am looking for some reports back.

Thanks in advance

cheers Greg

With 35's you wont strip out a ring and pinion, even in 4.88 flavor. You will break a birf or an inner axle before anything goes inside the pumpkin.

Greg,

The answer to your question is tied inextricably to which engine you have. With Alkaline's 3FE, I'd agree but something tells me that's not what's powering your rig.

Cryo treating does work.

Another thing that can be done is to shot peen the gears. I've read that peening the root of the gear improves strength significantly. Peening the faces is also beneficial as the shot creates many little indentations that hold the gearoil on the face. This puts the lube wear it is needed and allows the gear to run cooler. Cool parts are strong parts.

Mainly depends on what you want to break first - the birf's or the pinion
