What weight oil in the kf
 

Hi what weight oil are you guy's running in the geared diff on astroturf ?

i know some of the guys ive chatted to have put 3000 in it. Ive changed mine from kit to 6000. So its quite low.

10k on high grip stuff which felt very good...

15k works a treat

Cheers guys think i'll try 10k and see how that goes

It also depends on your track.. isit bumpy? if so then you need to lower the oil. if its smooth and flat you can get away with thicker oils. I've a range in my box of 3k, 5k, 7k and 12k.

I used 7k on a bumpy track last week and it felt great.

Hoping to get to RHR this weekend to give it a try got a full range of diff oil's so can have abit of a play with oils start at 10k then i can go higher or lower

How come the kf uses such thick oil in the rear diff, most other cars use 1-3k

They dont, on high grip 10k is pretty normal..

Some of the TeamC UK guys were running 20-40k in the TM2's on high grip.. I ran 8K in my Xray 2wd and 10k in the 4wd...

Outside when its slippy its another matter... although there is a ball diff for that..

I've used 20k since we bought the car out.

There is a difference is size compared to some of the other diffs on the market, therefore not all can take the same thickness of oil.

I'm mainly going to be racing my KF on grass, some areas are a bit bumpy. What diff oil would you recommend? I do plan on getting the ball diff as this seems the way to go but at the moment I will just be using the gear diff.

Can anyone offer some advice on this please?

Anyone??

Hi i'd start at 10k see how that feels then you can go higher or lower if you need too i have 20k in mine and it was very good on high grip astro

Ok cool, thanks Paul.
