Different size pinion or spur gear in the diff... I think Xray makes them .

are you asking different size diff gears? I don't think you can change that.

There are many products with MOS2 (Moly Disulfide) some are like a grease and some are very thick and used to lubricate threads, Molykote is brand that we have in the UK that's makes such products.
Another type of product you could use is motorcycle chain lube, some are dry or wax type.

I ran the pindowns at a local high bite carpet track and all my XB4 wanted to do was traction roll no matter what I did to my setup.

Will steel diff gears help on low to med traction tracks by slowing the diff rotation?

It'll depend on your set up, you'll want 1.6-1.8mm rollbars front and rear, but beyond that yes, you'll need to trim the tires, outer and likely inner rows, to start.
Give them a try, 9/10 guys at my old track used them
1-2 rows on inside of front.
2-3 rows on outside of front.
0-1 row on inside and outside of rear.

Malin getting her Xray XB4 dialed in on high grip EOS carpet at David Ronnefalk's new track in Sweden.

I noticed that my temps went through the roof running steel ring, pinion and diff internals. I switched to the new composite internal gears along with the composite ring and pinion gears (shimmed the pinion gear) and there was a 20 - 30° F drop in temps and the car is noticeably faster. Typically on low bite surfaces you would run lighter diff fluids and on higher bite surfaces you would go up in fluid weight, going with heavier parts isn't the answer

what motor are you running? im running a 5.5t. i think with mod steel is the way to go, stock plastic is best.

Steel gears are the absolute way to go.
