Chris Doughty put in the TQ at last weekends Players and finished 3rd overall using the gear diff - he ran 7,000 cst oil in it.

Cheers Guys (Craig, Jamie & Jimmy) :thumbsup:

I'll look at starting with 3K and see how it goes.

Raymond.

7k obviously proved to be really good at Worksop but that's on a cork surface, which is fairly loose traction. 7k on Loose traction tracks will help prevent the car from diffing out under power.

On a high grip track you shouldnt really have any issues with the car diffing out which enables you to go much lower on the diff oils. this allows lots of quick rotation which is good on tight technical tracks with plenty of grip.

Diff oils vary from track to track, so best thing to do is have a play around and see what works for you. :)

I think the rule is ,less grip more K,5k up ,more grip(full carpet track) 5K down.
Im waiting and waiting to get this gear diff,in Tresrey they have allready got it ,im think more 3 weeks and is for sale in europe ,let cross fingers :thumbsup:

MB Models are stating that they expect their stock in later this week.

So could someone give me a run through how these work over the standard is there an tec spec on the Durango site

I have been looking for a diff oil comparison chart as I presume diff oils are the same as shock oils and that every oil is slight different unless they are all measured in cst.

As far as know all diff oils are measured in cst.

Just stick with Team Durango oils so you know exactly what your using. All the team drivers will more than likely be using TD's oils, so using their oils will make it easier to copy set ups from the website. :thumbsup:

Is this worth upgrading over the standerd diff

In my opinion its defo worth having a geared diff as an option.

The ball diff seems better suited to low grip tracks as it helps generate traction without diffing out.

The geared diff is great on high grip tracks such as carpet or astro. Your able to achieve more rotation and more drive in a straight line.

Geared diff also has the advantage of fit and forget for most people. The only parts you ever really have to replace are outdrives when they wear out. The ball diff requires more maintenance and replacement of parts.

Both have their advantages and disadvantages so by having one of each, you can choose which to run depending on the surface.

Pardon my ignorance but when you mean diffing out, is this when the tires rotates faster than the other? so when your track is low traction do i need a lower wt oil or heavy?

thanks

It's when the inside wheel breaks traction under power.

I'm guessing a using a stiffer oil on low traction slows the diff operation down and thus helps reduce this. On high grip, a lower weight oil can be used as the available traction reduces the chance of this happening.

tnxs, will have to try to bring in heavier on my diff and see what happens...

so on a damp astro track with 650cst oil in the diff it is too light and will spin out so need to go higher?
what would be a good starting point for diff oil for a astro and grass track

For Astro i guess 3 or 5K would be good .

Hopefully I will try it this Sunday at Broxtowe and see how it goes, fitted a Arrma diff with 3000 diff oil, not sure if i should run a little thicker as its only a 2 gear diff but wont know till i try it.

Concept give us the feedback.
i think with two gears is a litle bit diferent the feel to a four gear diff isn`t ?

so 650cst is to thin by the sounds of it then it only around 45wt oil

Well I've got a diff on order now but without sounding stupid once this is fitted you can still adjust the slipper clutch:confused:

Yes mate .
