GPM Racing Hardened Steel+Aluminum Front & Rear Adjustable CVD Drive Shaft+Hex Adapter (+2mm) - 20pcs Set for Traxxas 1/10 MAXX (TXMS123AHEX2)

Precision front and rear CVD upgrade for TRAXXAS MAXX

This 20-piece upgrade replaces cross-pin drivetrain components with adjustable constant velocity joints and reinforced hex adapters intended for TRAXXAS MAXX chassis. The design pairs hardened steel joint cores with 6061 T6 alloy bodies and increases axle diameter from 6mm to 8mm to improve torsional strength while minimising added mass.

The adjustable CVD configuration permits concise driveline and suspension geometry tuning; the claw-style hex adapters eliminate the pinhole to provide a more positive mechanical engagement with the wheel hex. Track width grows by 2mm per side when installed, which alters roll stiffness and lateral balance and should be considered during setup.

Bearings have been updated for the thicker axle and the included 8x16x5 bearings are provided for correct fitment. This set is engineered as an aftermarket drivetrain upgrade for TRAXXAS MAXX platforms and installers should verify bearing seating, shim stack, and driveline alignment during assembly to ensure long term serviceability.

What checks ensure correct bearing preload and end float?

Install bearings dry, apply shims incrementally to remove lateral play, then rotate and recheck runout; recheck after a short test session as components bed in.

Are there recommended clearances for wheel hex pockets with the claw adapter?

Ensure wheel hex pockets are free of burrs and distortion so the claw engages fully; a snug but not forceful fit gives the best load transfer and reduces stress concentrations.

What inspection routine is advised for long-term reliability?

Regularly check joint boots, bearing end float, and adapter seating after heavy runs; replace bearings or shims at the first sign of measurable play to prevent secondary component damage.

How does the 2mm per side track increase affect chassis tuning?

A wider track raises roll couple and can shift the balance point; expect to make minor adjustments to shock rates or anti-roll setups to restore the handling characteristics you prefer. Write Product Review Please sign in your account before you can write any review. Sign In Close
