|  TRX4. Is there much difference between 9T and 11T pinion gear?
Is there much difference between 9T and 11T pinion gear? I wanted to get a 45T Spur gear and a 9T pinion gear. My shop only had an 11T pinion gear for my TRX4 Sport. I have no clue about gearing. Is a 2T difference that substantial? I use this truck for competitions. So trying to get the best performance out on the rocks. Thanks! |

 9/45 I what I run in my trucks - first gear is very low. I like it personally.... all depends on your power, tire size, driving style, etc. 2 teeth is a noticeable bump, but not a ton of difference imo. Try it and see! Always good to have a variety of pinions on hand, some motors seem to like higher gearing (Holmes Crawlmaster) and some work better lower (Holmes Trailmaster) | |

Since you dont have the 2 speed you might not want that 9 tooth pinion as it takes away top speed in favor of creep ability. I think you'll be happy with the 11/45 setup.

Stock sport is 39/17 I believe? So 45/11 is quite a bit lower geared already. I would run that first and see if you want more, specially with the sport single speed trans.

Appreciate the input!  This is strictly for comps. So I don't mind if it's slow. I'll try the 11T and go from there. A little speed would be a good thing if I'm running out of time. Thanks! |
