my initial slop, after two race days, has stayed at that point and has not increased after 4 more race days in mod
Not sure what kind of a business model makes parts for discontinued products.......

I want to know the same, the price of the 3racing gear diff is lower than any other.
On 3racing blog says:
Can anyone confirm this?
On 3racing blog says:
Gear Differential 37T and 38T are workable with 3.5 T to 4.5T modified motors, it fits all car models if some right adjustments of the chassis are made.

I put my diff together on Frinday night, raced a full day Sunday and had zero issues! The diff makes a nice difference on the track. Corner speed was up and kept very consistent through the day.
I built the diff as per instrcutions with Associated 1000 oil. VERY little leak at first, but it stopped.
Over all I'm happy and glad I bought one.

If you hold the spur and one wheel, if you try turning the other wheel it should move only the small amount to take up the slack though.
It should feel pretty smooth if you hold the spur and just turn one of the wheels.

I also greased the O-ring before putting that into position.
Pictures are good, but too small.

FG sticky grease
Right, don’t shoot me down and probably wouldn’t be right for a top racer,
But for a club racer have you tried FG sticky grease FG06512.
I now use it in Tamiya mini gear diff but also use it in spec-r diff fitted in X-ray T3.
It helps stop the wheel spin out so much when it lifts in corners,
gives less free play in the diff and dose not leak out. Also because the gears do not spin so much makes it last longer.
I’m not a top Touring car racer but not had to rebuild the r-spec diff since I’ve had it.
Might not be the right way for top racers but for a club racers works great.
I got a spec-r diff because wanted something which stayed smooth and could put in car and forget,
unlike ball diff which after a few races needed a rebuild.

Guys, I build and tested the 3Racing gear diff today. Package wise 3Racing is better, it includes everything you need for operation (37t and 38t pulleys, bigger internal shims for the outdrives, metal cross shafts, 3.5mm drive shafts blades, Silicone Oil: I don't know the viscosity coz there is no label or info on the bottle, RUBBER GASKET which is good compare to the paper one from Spec R, 2x diff bearings and some various thickness bearing spacers to make the diff fit to some car models)
During building I felt that the casing around the outdrives are a bit tight, so I put some grease on the out drive shafts and this helps smooths it out a bit. After a few runs testing it today the diff is smooth like butter. And the best part for me over the Spec R is there is NO LEAK at all. Overall I m very happy.

After running the spec r gear diff for a few races and experience failure too, building the 3racing gear diff brings my confidence back... The overall quality of the item are at least double the spec r standard, well at least the shims are double the size while it's not only one piece, but two pcs required on both ends while the rubber gasket is recyclable and most importantly it's cheaper by a third of spec r!
I just can't wait to try it on the track. Any1 has done it and how's the reliability of the 3racing gear diff?
Thanks
P/s: I'm running a TRF 416 FX (Smokem chassis) and I believe it should fit the X Ray T3 chassis as well.... Cheerios

I've tried 150cst to 2000cst and I have yet to see anything over a really well set xray ball diff with associated grease. It seems the ball diff has a bit more slack when you put the power down. Almost like it has a small amount of slip even when there isn't. I was immediately quicker when I put the ball diff back last week on a low grip carpet layout.
Dont get me wrong, it works ok, but I find theres more downsides to the Spec-r diff than originally thought. When using thin oil the thing leaks a lot and when I thicken the oil it has poor performance so I cannot win with it. Tried more gaskets etc, differnt o-rings, still no joy. I can see it working outdoors, but indoors its not doing the job I want it to do. As for maintenance free........................
