Aluminum Pro Pinion Gear 1/8" Bore 48P 19T (RRP1319)

Aluminum Pro Pinion Gears are precision‑machined from aircraft‑grade aluminum, lightened to reduce rotating mass, and finished with a hard black anodize for durability. The 19‑tooth, 48P pinion has a 1/8" bore and includes a 5-40 set screw for secure mounting, making it ideal for fine‑tuning gearing to optimize speed and torque on RC cars. Designed with on‑road performance in mind, these pinions can also be used off‑road with the right gearing.

This 19T, 48P aluminum pinion pairs with standard spur gear setups on RC cars, offering a reliable balance of torque and top speed. The hard anodized finish resists wear during long sessions, and the 1/8" bore ensures compatibility with common motor shafts, making installation straightforward.
