Paired with a 76T spur gear got my traxxas slash 2wd to 51mph before impersonating an airplane with no pilot and only half a wing(not pretty) Get a wheelie bar if your gunna do gearing this high, otherwise you might as well kiss your body goodbye. would recommend tho, put these gears through hell and back but they still hold strong.

What reviewers say

All three reviews are 5/5 and praise the pinion gear's durability; one reviewer says it held up under hard use at high speed with a 76T spur gear. Two reviews mention the 39T variant specifically. One review is mainly about customer service via text rather than the gear itself, so it says little about product performance. A reviewer using high gearing advises fitting a wheelie bar, noting the risk of losing control at speed. The sample is small, so the overall picture is limited.

  • + Durable under hard use
  • + Holds up at high speed and gearing
  • + Good track performance
  • − High gearing risks loss of control without a wheelie bar
