Hey guys, I have some curiosities about my choices in gear oil for the rear diff of my truck. I used to monkey around with RC toys a lot. I remember that I could remove the diff in 1 of those, empty out the oil & stuff it full of thick axle grease & it would act like a limited slip diff - cool trick back in the day. I asked my parts guy recently about putting in thicker diff oil to hopefully do the same trick for my Ram. There were only 2 options & I dont remember what they were, but 1 was twice as thick as the stock oil. He said I would regret it come winter time. That kind of makes sense since I am in Iowa, but I still want to increase the 2 wheel traction since my truck is 2wd. Do you guys have any advice?

 

Never heard of that trick, I know I wouldn't run anything drastically thicker than recommended...


I can't help you on whether it would work though, sorry.

 

Your RC cars aren't dealing with the torque of a v-8, nor the weight of a full-sized truck. Thicker oil isn't gonna help. One trick you can use though, if you are in a limited traction situation, and one wheel is slipping, put light pressure on the brake, to help distribute the torque.....

 

Or purchase a Detroit Locker for the rear

 

My factory limited slip diff works just dandy. The deepest sand and silt has never got me stuck. I do need to change the diff oil, though. I'll put it on my list for tomorrow.

 

Or just throw a fat lady in the bed for traction.. they can easily be found at your local trailer park!

On a serious note you can get a good posi put in for not that much scratch

 

Or just get a good set of chains.

 

Lincoln locker!

 

Lincoln logs!!!! Ohh wait nevermind......

 

Only "trick" I've ever heard of that works is to two foot an open diff. Applying slight pressure on the brake with the left foot while giving it gas will keep traction on both wheels. Slightly applying an e-brake will do the same thing...
