The RR237S is a two-piece front and rear main drive shaft set engineered by GPM for the Axial Racing RR10 Bomber, manufactured from #45 steel for consistent dimensional stability. These replacement shafts are intended to restore drivetrain alignment and serviceability on RR10 Bomber scale crawlers.
Supplied as a matched front and rear pair, the shafts require verification of spline engagement and coupler fit before installation. Ensure drive pin retention and hand-rotate the drivetrain to confirm free rotation and correct alignment prior to dynamic testing. Use only as drivetrain components for scale RC vehicles.
Upgrade guidance: this direct-replacement steel option is targeted at maintenance and durability improvement rather than performance tuning. Correct installation maintains factory geometry and reduces stress on adjacent gears and bearings, extending component life under typical crawling loads.
Install these matched shafts to replace worn or damaged mains on an RR10 Bomber chassis and verify fitment and smooth rotation before operating under load.
