This spur gear serves as a standard replacement for YZ-4SF series chassis, designed specifically for use with dual pad slipper assemblies on 1/10 scale RC race cars. The component corresponds to the DP48 designation and carries 87 teeth, matching the 48 pitch tooth spacing listed in the product details.
As a drivetrain part, the gear is mounted to the slipper hub and functions within the slipper system to transfer motor torque into the gearbox while allowing controlled slip under load. During installation confirm correct pinion-to-spur mesh and check the dual pad slipper pads and preload to ensure reliable engagement.
Tuning note: the 87T spur determines final driven speed and torque range when paired with your chosen pinion; changing spur or pinion tooth counts will alter acceleration and top speed, so replace parts as a matched set and recheck slipper adjustment after any change.
