The Yokomo PG-4825A is a hard-coated aluminium pinion created for hobbyists who want dependable gear contact and efficient power transfer. With 25 teeth and a 48 pitch profile, it pairs smoothly with matching spur gears for consistent on-track behaviour.
The hard coating on the PG-4825A reduces surface wear while keeping the part light. That means you get a durable pinion that does not add unnecessary rotational mass, helping the car stay nimble during acceleration and cornering.
This part suits models and kits that use 48 pitch spur gears. Use it to replace tired stock pinions or to tune gear ratios while preserving proper mesh and transmission efficiency.
