TRAXXAS X-MAXX 8S Harden Steel #45 Front/Rear CVD Joint + Aluminum Wheel Hub Hex by GPM TXM8170N/JT  [TXM8170N/JT]

This 10 pcs set is specified for TRAXXAS X-MAXX 8S owners who need stronger outer shaft CVD components and a light but stiff wheel hex. The kit replaces the standard aluminum CVD joints with hardened #45 steel at the joint surfaces while providing 6061-T6 aluminum wheel hexes to retain low mass and tensile strength.

Contents included in the shipment are listed here for clarity so you can confirm parts prior to fitment: CVD joint - 2 pcs, Wheel Hub Hex - 2 pcs, 3.5 steel pin - 2 pcs, Set screws 5x5 - 2 pcs, M5*4*20 screw pin - 2 pcs. These are intended for the outer shaft joints of the CVDs as stated in the part location.

Installation notes: the joints are meant to replace outer shaft CVD pieces; check axial play and socket fit during assembly, tighten set screws to manufacturer torque guidance for the X-MAXX hub system, and verify pin retention after a short test run. The aluminum hexes use common hub mounting geometry for X-MAXX wheel setups but confirm spline compatibility before final installation.

Tuning role and maintenance: upgrading the CVD joint material to #45 hardened steel targets wear resistance under high loads, especially with 8S power systems. The 6061-T6 aluminum hexes balance stiffness and weight to help maintain predictable wheel response. Periodic inspection of the steel pins and set screws is recommended after high-stress runs.
