Default Different Diff oil effects

Can someone explain to me the effects of changing diff oil. I am running 5000,7000,2000 in my eight. If I go up or down in viscosity how does it change the handling? These types of diffs are new to me and I have no idea what I am doing.

Heavier front diff oil will loose some off-power steering but the car will be smoother entering turns and easier to drive.It will also pull better out of turns.

Heavier center will also loose some off power steering but the car will give more on power steering and more acceleration

Heavier rear will loose some off power steering but will slight better on power and the rear will feel like it has more traction because it won't tend to loose suddenly the grip as it might happen with 1000 diff oil(not always the case though).

Its affect btw

But back on topic, a higher number will be a thicker oil, making your diffs run a little slower but smother power, a lower number will be thinner so if you were to full throttle it will most likley spin the tires (on dirt) more then it would will a higher number oil

Go to the link and download the Hudy Off-Road & Truggy Setup Guide. 3rd down on left. This has everything you need to know about what changes do what when it comes to diff oils and everything else you may have a question about.

Actually, "effect" is correct as used. He was asking about the effects of using different weight diff oils (correct usage of the word here).

If he had said "How will different diff oils AFFECT the handling of my buggy ..." (or something like that), then "affect" would have been correct.
