spur gear tooth question

[feelthegirth]

is there a difference in performance between a 38 tooth and a 40 tooth spur gear

More teeth= more low end power, less top speed. Fewer teeth= less bottom end, more top speed. The oppisite applies with pinions or clutchbells.

whats better overall between a 38 vs. 40. i play in the dirt

 

[Metalhead Matt]

That's impossible to answer. Can't see how the truck performs from my house. You probably wouldn't notice a difference.
