I'm suprised you aren't chewing up the 45 tooth pinion gear because you have a mismatch.

18 + 45 = 63

23 + 41 = 64


When doing gearing, you want the sum of the first set to match the sum of the second set. This ensures the same amount of gear mesh in both sets.

You could use a 39T pinion for second and pick your first gear pinion and spurs based on what you have and/or want.

Give some thought towards a 41T 1st and 39T second with highest spurs you could get (so 23 and 21) if you have a lot of wheel spin off the line

My personal setup is the 43T/39T pinions with the stock red spurs (19 and 23). I have a 18ss with RD logics turbo II pipe and with this gearing I reduced my wheel spin (from the stock gearing)

Good luck and nice build.


39T Pinion

yeah you can use any 1st gear pinion with 2nd gear pinions but i think youll need corresponding spurs with it..

watch this clip.. drift stage-d. he uses different color pinions and drifts like a god

LOL!! hahahah! Too funny man!

That car in the video was outrageous - Not only can it drift like a monster but it looks way good doing it! The whole HPI lighting up on the side thing was incredible. Very cool! - thanks for posting it HeLLsGoD.

I recently purchased the gold pinion gears and I will be heading out to track this weekend so hopefully there will be some kind of difference in bottom end. We will see...

Well, we are about to find out if the GPM center shafts are 18TZ tough.



Sorry if this is a bit off topic.
Could you explain a little about those rear body mount posts and maybe a link of where to get some like that. They really look effective.

OK WOW! So now I definitely want a TZ! That engine is no joke. Glad to hear the center shafts are holding up Fox, what are your plans for replacing that spur gear? I haven't seen metal or hardened spur gears for our cars and it seems like you're gonna need them.

Where did you buy the center shafts fox? I've searched around but haven't found a place that sells them?
