HRSTRXF39W05 - +5mm S2 Spring Steel Portal Drive Stub Axles TRA Trx-4

This product is a pair of S2 hardened spring steel portal drive stub axles designed to upgrade or replace the factory portal stub shafts on Traxxas TRX-4 crawler platforms. The extended axle design increases the vehicle’s track width by 5 mm on each side, improving stability on uneven terrain and providing additional steering clearance for larger tires. CNC-machined spring steel construction delivers high strength and resistance to bending or breakage under heavy crawling loads. Blue anodized aluminum spacers and locknuts are included to complete the widened portal assembly while maintaining precise drivetrain alignment.
