Gear diff in KD
Hi all,
at yesterday's welsh regional two of the guys running KDs ran into problems with their ball diffs. Mine is on its third meeting & seems to be resisting slippage, but does feel gritty. And after building the car, and pitting opposite someone who had to get their diff out between rounds for a rebuild, I'm thinking that's not something I'd like to do under pressure. Is anyone here running a KD with the optional gear diff? If I used a light enough oil, could I get a similar feel? |

You are not alone I was wondering this myself. On my 4th rebuild

It's frustrating because the engineering that went into that gearbox is astounding. It's a beautiful bit of CAD / CNC work. but after running a KF2 where the diff is accessible after undoing 4 screws, having to take the entire rear end apart is a nightmare. I can't believe they overlooked that. A simple single removable width plate design at the rear could have mitigated these problems without compromising rigidity or the seal. It wouldn't have been pretty, but it would have meant being able to pop the diff out the back, horizontally, by popping out the driveshafts & undoing 4 screws. My gear diff should be arriving today |

are you sure you have no slip?
i did one set on my first run, fitted some new plates and the nitride balls and the car has done 4 meetings with still a smooth untouched diff my first failure was too tight slipper and too loose diff

I've been running a gear diff in my KD for a while now. Very pleased with how it drives in the wet still. The ball diff might be slightly easier to drive but I have no issues turning equally quick lap times with the gear diff. I run 2000cst in mine.

Nearly a year on...
Hi Guys,
I have recently gotten a KD and I am getting problems with the ball diff. It seems to be impossible not to have it slipping. Don't know if i have done something wrong. I am considering going to a geared diff. One of our junior members says he feels little difference with his. What are your thoughts?
