PRO627301 Traxxas Slash/Stampede 4x4 Pro-Spline Rear HD Axle Set

A pair of pre‑assembled Pro‑Spline HD rear axles engineered for Traxxas Slash 4x4 and Stampede 4x4 vehicles, these hardened steel axles replace stock plastic shafts with durable, smooth‑sliding 6‑sided splines to better handle power and reduce drivetrain failures under aggressive running.

• Hardened steel construction with black oxide finish for improved strength and corrosion resistance.

• True 6‑sided sliding spline design lets the axle slide smoothly throughout suspension travel.

• Pre‑assembled units ready to install — no complex assembly required.

• Zinc‑coated snap rings securely hold drive pins in place during use.

• Replaces fragile plastic rear shafts to reduce the risk of stripping under high torque.

• Helps lay down serious power without drivetrain hiccups when accelerating or landing jumps.

• Designed as an ultimate rear drive upgrade for Slash 4×4 and Stampede 4×4 trucks that want stronger, more reliable driveline performance.
