Would this do the job? I could not find a 80wt for the front.:

What's the difference between a 1000 and a 10000 and a 100000wt? how do they affect the performance of the diff?

The stiffer or higher number means less diff action. The thicker oil tries to make sure both tires turn closer to the same speed.

ohhh good to know thanks....

Well, what weight of diff oil do you recommend for a truck with full aluminum parts and a 1950 motor as well as 20 cells of batts? I want it to be fast and controlable.

7 k front 5 k rear.

You mean 7k= 7000 or 70000?

k = 1000

I got some mugens 4k today for like 5 bucks at my local hobby shop.

LOL, Captain... this sounds contradictional...

'i want my truck to be controllable, i use 20 cells......' pretty funny sentence if you ask me..

Why not having a fast truck at 24V and controllable at the same time?! everything is possible, you know.

C'mon captain..

You know what i mean..

2000 watts on a few lbs is controlable, it just takes a gentle finger..

If it stays in a straight path at full telt, thats very controllable for me.:dft009:

Again.. a gentle finger will help..

No other way around it, your gonna need some 'sticky' tires to stay from a stand still, just be gentle.
