Thanks because I have a box full of spares lol

Hi everyone
Is this the gear diff to get.

Thanks in advance. (was not sure if there was a revised model)

"Diff" oil and "Shock" oil are the same in that they are both silicon oil, just shock oil tends to have much lighter weights (Diff oil typically only goes down to 1000cst, shock oils down to 200cst or thinner). I would start with AE 80wt (1000cst), I really liked this on our high bite indoor track.

Thicker oil in the rear seems to help the car rotate more as traction comes up. I also like 70-80wt shock oil for high grip! For low traction I like to start with 30wt shock oil until bite comes up.

I run mainly 50w on medium grip tarmac outdoor

About oils.

Shock oil is like "slick fluid".
Gear oil is like "glue fluid, it glued or made more sticky fingers" when you
put it on skin.

Anyway, if y are hardcore y can use shock oil in gear diff but it can "quickly" go away ;-)

I just prefer 800cst diff oil (sticky fluid) then 800cst shock.

;)

But all thing depend on what driver need.

Regards!

ok so i got my gear diff today. gonna be running on an indoor medium bite carpet track. 17.5 blinky, foam tire. should i run in front or run it in the rear? i see people doing either way and just not really sure, i am use to running spool up front and ball in rear.

I would stick with the ball in rear, gear up front with something really heavy in it like 200k-500k diff fluid or cleaning putty.

Just be aware that a gear diff in the rear gives a LOT of rotation compared to a ball diff, even filled with shock oil as light as 15 weight.

On carpet, most other brands that have had gear diffs for a while have already found out that it's too much for most carpet set ups, and run ball diff rear/putty gear front.

Guess the learning curve amongst the Associated crowd isn't going to take known principles and performance trends into account.

....and the geargasms continue!

If your running 15wt shock oil in the diff, thats probably why. Thicker oil is gives a more stable feeling... I absolutely love the gear diff in the rear on carpet for this car. My 416, not so much, but this car makes a LOT of traction and drives very well with a gear diff

Thats because the 416 not so much anything.

I got my gear diff today, and my bone blades are WAY to tight in the outdrives..

should i sand the outdrives or attempt to bend them open a little?

my stock outdrives are measuring .143 and the type r outdrives are .137-.139

and believe it or not, that take the fitment from perfect, to binding up tight..

ALWAYS sand/grind the cheapest part. That said, sand the bone blades a little.


I'm anxious to see what the IIC and Snowbirds brings in terms of high traction carpet set ups from the Team. I note that for asphalt in the rear 30wt - 50wt is common, as is eraser putty in the front, putting the TC6 right in line performance and set up wise with all the other TC gear diffs out there.

Sand the plastic blades takes 2 minutes.

I prefer to not use a ball diff in the rear cuz it slips.......

I've never used "diff" oil (always shock) and never had leak issues.

Perhaps sometimes things are made more complicated then necessary :ha:

I also want to see some super high bite setups with gear diffs.
