Are there any spur gears out there, other than hot racing or ECX, that will work on these trucks? Something a LHS would have in hand?

Is there any other spurpose gear available or some to modify48 Pitch. Stock torment I know has a 87 spur and maybe a 20 pinion. There are numbers stamped on gears, or count the teeth. I have changed out the pinion a while back, so can't remember stock. Here's some info;
Low Gear (or high gear ratio):
-Smallest pinion, largest spur gear.
-Fast, punchy acceleration, lower top speed.
-Usually less strain / heat on the ESC and motor.
-Longer run times from a single charge, fast pull away, but easier to control at top speed.
High Gear (or low gear ratio):
-Largest pinion, Smallest spur gear.
-Slower acceleration, higher top speed.
-Easier to pull away due to slower acceleration which can mean more grip (less spinning out) on some tracks.
Hi Batone76, I just found out today. after upgrading my torment to a Brushless 3660 4300kv, Initially left the original 87t with a 23t bore, bit after destroying my slipper clutch, went to a local hobby shop and found the hobby works spur HWC-60222 is 81t 48p, and the pads. It leaves the perfect room for a bigger pinion, so I went 81/25 not bad at all. No modifications at all just install them. It is ridiculously fast, I got 82km/h today with 2s lipo and Willies at any time. I reckon with 3s would be undrivable!! lol..Is there any other spurpose gear available or some to modify
Hi Mate, yes 3660 motors come with a 5mm shaft. Cheers.Just clarity. You have the pinion for the larger shaft on motor? The size of 5mm is not the normal/standard size pinion gear shaft size.
It really don't matter to me, just want it to be clear for others.
Thanks for the feedback.
