The JAZRIDER BUL-18000-GU gunmetal alloy front knuckle arms are produced as a straightforward durability upgrade for HPI Bullet owners. They focus on long term serviceability and consistent steering feedback during everyday use.
Made from gunmetal alloy, these knuckles reduce flex compared with standard plastic options and help keep wheel alignment stable under repeated nitro engine loads. That stability reduces frequent adjustments and downtime.
These components are intended for HPI Bullet 3.0 MT and ST models and install with common RC workshop tools. Routine checks of fastener tightness and pivot cleanliness will keep the knuckles performing well.
