Product Description

LeeSpeed 84 pitch (84P) pinion/spur gears were released last year, but this is the first time they've been available large enough for oval racers. 84 pitch gears provide 2 slight advantages over 64P gears:

  1. They are a little more efficient due to the decreased angle of attack on the teeth. You can feel the difference when comparing rolling 84P gears together versus 64P gears.  The 84P gears are much smoother.
  2. Secondly, when you make a single tooth pinion change, it's a smaller rollout change. This let's you fine tune the rollout a little better.

These are surprisingly less prone to stripping than you'd think because there are 2-3 teeth touching at all times. At IIC in Las Vegas this year, even some 1/12th open mod cars were using them, so they can handle the powerful motors.
LeeSpeed took the 2nd effort and drilled counterbalancing holes on the back side of the pinion to balance the set screw.  Really nice!

This pinion set is a set of 19 pinions: 74T-92T (55-68T 64P equivalent)
