The Tamiya 51090 950 Bearings set supplies reliable rolling performance for TB-Evolution IV and TRF415 chassis. These bearings are made to withstand repeated runs while keeping rolling resistance low.
By cutting internal friction and standing up to wear, these 950 bearings help your drivetrain run cleaner and cooler. That stability helps you keep steadier speed and predictable steering on both race days and practice sessions.
Designed to pair with the TB-Evolution IV and TRF415 Reversible Lightweight Suspension Kit, the four bearings are an easy swap for maintenance or upgrades. They work well as replacements during routine service intervals.
