GPM Racing #45 Steel Front+Rear Driveshafts (100mm-115mm, 135mm-162mm) for Axial 1/10 RR10 Bomber 4WD Rock Racer RTR (RR237S)

Technical overview RR237S main drive shafts

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.

Specifications

• Item Front + Rear Main Drive Shaft set, 2 pcs
• Material #45 steel
• Model Number RR237S
• Compatibility Axial Racing RR10 Bomber

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.

How do I confirm spline compatibility?

Measure spline count and diameter against your stock shafts and check coupler seating; the RR237S is produced to fit standard RR10 Bomber spline profiles but verification prevents misfit.

Are these heat-treated or surface coated?

These are fabricated from #45 steel for mechanical strength; perform routine cleaning and light lubrication to manage corrosion risk in exposed conditions.

Recommended inspection routine?

Inspect for straightness, spline wear and secure fastenings after impacts or extended use; replace associated pins and check bearing play when fitting new shafts.

Intended use and limitations?

Designed as replacement parts for scale RC drivetrains on RR10 Bomber platforms; they are not performance aftermarket modifications and should be used where matching OEM geometry is required. Write Product Review Please sign in your account before you can write any review. Sign In Close
