This adjustable main shaft is an aftermarket replacement built for AXIAL SCX10 II platforms. It pairs an aluminum 6061-T6 shaft body with a hardened steel #45 universal cross head to reduce rotating mass while keeping the joint durable for slow-speed crawling and drivetrain tuning.
The universal swing cross head increases steering articulation and axle tilt without altering chassis pickup points. The lighter alloy shaft helps reduce inertia on the axle, while the hardened steel cross head preserves reliable coupling under load. A pin-lock design secures the cross head and the kit includes white silicone O-rings to cushion contact between the head and shaft body.
Length adjustability allows fine fitment: front span 115-125mm and rear span 130-140mm measured between the mounting reference points. The set comes with screw shafts and silicone O-rings to fasten the assembly; always verify hub-to-hub measurements on your SCX10 II before final assembly.
Use this shaft to tweak axle geometry and improve articulation on AXIAL SCX10 II crawlers; confirm adjustments and inspect pin-lock and O-ring seating after initial runs.
