Upgrade to a metal drive gear for your HP141 or HP141S RC car to boost durability and drivetrain reliability. This guide explains when to choose the genuine 16402G part.
Quick answer
If you want a more durable drivetrain for your HP141 or HP141S, the BEZGAR Metal Drive Gear (16402G) is a direct-fit upgrade that resists wear better than the stock plastic gear.
Why upgrade to metal?
The stock drive gear on the HP141 and HP141S is plastic. While it works fine for casual driving, it can strip or wear quickly under higher power, rough terrain, or frequent use. A metal gear eliminates that weak point and keeps your drivetrain running smoothly longer.
Trade-offs to consider
Metal gears are heavier than plastic, which adds a tiny bit of rotating mass. In most cases the durability gain far outweighs this, but if you are building an ultra-light racer, you might prefer to keep the stock plastic gear. Also, metal can transmit more noise and vibration—nothing extreme, but worth noting if you run your car indoors.
Decision rules
- Current gear is damaged or worn: Replace it with the metal 16402G gear. It costs about the same as a plastic spare but lasts significantly longer.
- You run your HP141/HP141S on rough surfaces: Gravel, grass, or dirt tracks put extra stress on the drivetrain. The metal gear handles this much better than plastic.
- You are upgrading other drivetrain parts: If you are already swapping to metal axles or a metal center shaft, the metal drive gear is a logical next step for a fully reinforced drivetrain. Check that other gears in the drivetrain are in good condition to avoid uneven wear.
