Axial SCX10 II Rear Straight Axle Upgrade JR-AS203 by Jazrider  [JR-AS203]

Scale Rear Axle Straightening Kit for SCX10 II

This is a scale RC rear straight axle adapter intended for use with the Axial SCX10 II platform, listed as model JR-AS203. Fabricated from aluminum, the adapter adapts the stock rear axle mounting toward a straight-axle arrangement on scale crawlers and trail rigs, serving alignment and support roles rather than altering the driveline.

For installation, experienced builders should remove the affected rear axle parts on the SCX10 II, fit the adapter to the axle or housing where required, and fasten using the vehicle's supplied hardware. Check clearances for tyres and suspension travel during reassembly, confirm wheel alignment, and avoid overtightening. Inspect mating surfaces and fasteners before finishing the job.

Used as a tuning part, this adapter helps tighten rear tracking and can reveal how axle geometry tweaks influence low-speed crawling and traction. It pairs with common scale upgrades like different wheel and tyre combinations and suspension adjustments; introduce changes stepwise to evaluate handling differences.
