JConcepts 48 Pitch TLR "Silent Speed" Machined Spur Gear. These gears are compatible with the 22 family of vehicles, and are available in multiple tooth count options to fine tune torque and top speed. 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.

Machined, recessed dots on the outer edge indicate size while assembled within the slipper assembly for easy identification:
  • 1 dot = 70 tooth
  • 2 dot = 76 tooth
  • 3 dot = 78 tooth
  • 4 dot = 80 tooth
  • 5 dot = 82 tooth
Features:
  • JConcepts simple design and function
  • Precision machined for durable and concentric design
  • Machined to indicate size while assembled or stand-alone
  • Fits TLR 22 series vehicles
  • JConcepts - World Proven Innovation and Design

JConcepts 48P TLR "Silent Speed" Machined Spur Gear (76T)
These are really good replacements for the stock spur gear. If you are planning to run stock-spec racing, this is a great part and will last a long time.
