HB D4 - Durango differentials
 

I worry with original differentials on D4 so I think about it, when durango differentials work in Associated B44 why not in D4... :woot:

I was made special axle shaft for attachment bevel gear ,change one ball bearing for perfect gear distance and mill the differential house.

Now it perfect function :thumbsup:

sorry for my bad english :blush:

Wow...I might try that! How does it work compared to the ball diff?

I have not had problems with my d4 diffs. You just shim them properly, set your slipper and your good. But the work you have done is pretty cool. I like seeing people try new things.

To 4times: I do not know, I have not tested it on track, That I can say after this weekend :)

To bjcaldwe:That is true but I prefer tight slipper, on carpet and high grip track it is a problem :thumbdown:

this is a certainty :thumbsup:

On carpet with a hefty motor, I could see that becoming a problem. Is your car a wce or the non wce version?

It's WCE, i like geared diff more tahn ball diff, it's better for precision set-up.:thumbsup:

Sweet, keep up the good work.

That would be cool if it worked ......After running today our track was pretty hard packed lots of traction everywhere and my diff is pretty gritty after a whole day of racing , keep us posted .

Ben Cosgrove (HPI team leader in the UK) has done this to a Cyber10b.
Must say it worked a treat! Awesome amount of accelleration. It just looked like he was driving a fat durango.

It does work if done properly, and makes them go like stink!:D
