Trinity 25T Thin Cut Ultra Light Weight 48P Pinion Gear - TEP4025

The Trinity TEP4025 is a 25-tooth, 48-pitch pinion gear designed for use in competitive RC car drivetrains where reducing rotational mass is a priority. Trinity's Thin Cut Ultra Lightweight design removes material from the gear body without compromising tooth integrity, making the TEP4025 a popular choice for racers running 48P motor and drivetrain combinations. If you're looking for a 25T 48P pinion to fine-tune your gear ratio or replace a worn pinion, this is a direct, race-oriented option from a brand with strong credentials in competitive RC.
