TRAXXAS X-MAXX 8S Hardened Steel #45 CVD Drive Set for Front/Rear by GPM TXM8170N  [TXM8170N]

Hardened CVD drive set for X-MAXX

This 8pcs CVD drive set is built as a direct aftermarket reinforcement for Traxxas X-Maxx running on 8S. The kit uses hardened steel #45 for the main drive elements to improve wear resistance and withstand the higher rotational speeds produced by X-Maxx powertrains.

The design changes described by the manufacturer include a thicker dogbone section increased from the original 5.5mm to 7mm and a revised hex joint that replaces the original fastening method with a perforated alloy hex secured by a stainless steel pin. Those modifications are intended to keep the alloy hex centered under heavy loads and to reduce slippage between the CVD and hex during high-speed operation.

Included parts listed by the supplier are presented for reference: Hex Adapter - 2 pcs, Stainless Steel Screw Shaft M5x4x20 - 2 pcs, Set Screws 5x5 - 2 pcs, with Manual numbers 7750, 7737, 7756. The primary function of the assembly is to transmit drive from the gearbox to the wheels so the wheels and tyres rotate reliably at speed.

Use this set when upgrading drivetrain durability on an X-Maxx running 8S power, and check fitment and retention method during installation to ensure the pin-secured alloy hex is properly seated.
