This is an optional JConcepts 48 Pitch, 81 Tooth "Silent Speed" Machined Spur Gear, and is intended for use with the Associated RC10 B4, T4, B44 and SC10 vehicles. The heart of any R/C vehicle is its transmission, and at the top of the transmission lies the spur gear; an integral part of racing performance. Spur gears or straight-cut gears are one of the simplest forms of gear; however they directly influence the ratio, speed and sound of R/C vehicles and are an extremely important tuning option. These gears when meshed together correctly, provide the transfer of power from the motor to the transmission and are one of the key elements in the versatility and sound of a vehicle.

Silent Speed spur gears are precision machined making them uniquely concentric over standard or molded gears giving the user a consistent gear mesh allowing a more precise adjustment and more “silence” on the race track. The detailed machining provides a pattern vented area and secured slipper pad on both sides giving more consistent slipper performance. The gears are marked for size in 2 different ways so they are identifiable either assembled within a slipper assembly or as a stand-alone part. Silent Speed spur gears are also branded with the small JC logo for brand identification and authenticity. Already a winner, the Silent Speed Spur Gears scored a victory at the 2011 ROAR Off-Road Nationals in the 2wd Short Course Class in the hands of Ryan Maifield on his Factory Team SC10. Gear-up or Shut-up, with Silent Speed by JConcepts.

Machined, recessed dots on the outer edge indicate size while assembled within the slipper assembly for easy identification:
  • 1 dot = 69 tooth
  • 2 dot = 72 tooth
  • 3 dot = 75 tooth
  • 4 dot = 78 tooth
  • 5 dot = 81 tooth
  • 6 dot = 84 tooth
  • 7 dot = 87 tooth

Features:

  • JConcepts simple design and function
  • Precision machined for durable and concentric design
  • Machined to indicate size while assembled or stand-alone
  • Fits Associated B4.1, T4.1, B44.1 and SC10 vehicles

Best spur gear I've ever used. Makes setting the mesh super easy and consistent. Makes the car almost completely silent.
