Overview
Tighten up small drivetrain components on 3mm-diameter shafts with the Hot Racing Steel Shim Set in 3x4.4x0.1mm. This 10-pack of precision steel shims is the perfect tool for shimming 3mm-diameter axles, gears, and other small drivetrain components found across micro and mini-scale RC platforms — including 1/24 and 1/18 scale crawlers, buggies, and trucks.
Shimming smaller-scale drivetrains is even more critical than shimming larger vehicles — small amounts of slop in micro-scale components have a proportionally bigger impact on efficiency and durability. This shim set lets you dial in tight, professional tolerances on the smallest components in your build.
Key Features
- Precision steel construction
- 10 shims per pack — enough for multiple builds
- Designed for 3mm-diameter axles and components
- 0.1mm thickness for fine tuning
- Reduces slop between drivetrain components
Performance Benefits
- Eliminates end-play slop in 3mm axles and gears
- Reduces vibration and gear chatter
- More efficient power transfer in micro-scale drivetrains
- Extends the life of micro bearings, gears, and seals
- More predictable, consistent vehicle behavior
Usage Notes
Use a feeler gauge or trial fitment to determine the correct number of shims for your application. Stack multiple shims as needed to achieve the right end-play. Note: manufacturing tolerances of approximately +/- 0.02mm may be expected. Use clean tweezers when handling these small shims.
