Putty is very hard on the diffs that's why i dont pack it to full.packing it right up is not a good thing.I use 500k when a front diff is needed and i like it feels better then putty but that's just my liking.i run 4.5t boosted/turbo and the yokomo diffs hold up good with putty or oil.

The front end in general is very hard on diffs. I have felt a 500k diff and I wouldn't expect much braking/acc performance with steering. The putty diff I have run in the past was easily faster. I think this maybe more a case of how you prefer to drive. I saw a driver this weekend in mod driving very wide flowing lines like you would expect with a 17.5t. This worked well for this driver as he won the event but I wouldn't prefer this for myself.

Default fed up with the leaking

OK.... I am pissed now.

No matter how I build the gear diff (follow exactly a-z from video, instructions, etc), I still have the leaking issue.

I have 3 units now. Changed the internal gear to carbon now, change the green gasket paper to v2, the leaking issue still exists.

Now, my last attempt is to use the threebond gasket sealant.
Went to the hardware store just now, there are too many types of threebond gasket sealant. Didn't know which one to get.

Any recommendation on which sealant should I use???

Thanks.

rubber grease on the gasket and the orings stopped my xray gear diff from leaking so I am assuming it should work with the SpecR. Don't be stingy with the grease.

are you filling the diff all the way if you are it should only go slightly below the small gears when you fill it.I have a special grease for o rings i will be selling soon that will eliminate leaky diffs and shocks and is way better than anything used in the past.I have run the diffs with the grease i have for many runs and no leaks at all, and it is formulated for o rings and silicone oils.

Basically, I have tried all brand of grease, with a lot of amount, still the leaking issue exist.

Leaking comes mainly from the pulley & it wets the rear belt.

Last option will be the threebond sealant (I guess)

New spec-r gear diff for TC6 is available at TQ. Click Here



Try use 20k diff oil with 20% fill up will help to prevent leaking.

FYI, Thanks.

Or is this a "one time" use?

Anyone know if the Spec R gears will work in a Xray Gear diff? I've always like the material they use for the gears back since the TC4. Just curious if they will work.

So i notice there are 2 gear sets for the spec r diffs... A carbon set and nylon looking set.

I recently bought one with a carbon set.. chewed those out pretty quick... and now have an older diff off a friend and it has nylon set...

So which is tougher?
