Precision-engineered rear CVD kit

This rear drive upgrade for the Traxxas Slash 4x4 family is engineered to CNC-style tolerances, combining hardened steel axle sections with 6061 T6 aluminium knuckles to balance strength and mass for high-impact RC use. The increased axle diameter is specified to resist deflection during heavy landings while maintaining serviceability in the field.

Precision bearings are supplied to minimise friction and wear, and a spring steel hex secures the hub under torque loads. The assembly is intended as an upgrade to improve rear-end durability without altering the main driveline geometry.

Installation guidance: components are direct-fit for the listed Slash variants. Confirm rear hub clearance and inspect mating hardware before extended operation. This item is for RC-scale vehicle applications only.

Compatible Models

  • Traxxas Slash 4x4
  • Slash 4x4 Low CG
  • Slash Pro 2WD Short Course

Select this rear CVD and knuckle arm set for a precision upgrade that increases impact tolerance and long-term durability on Slash 4x4 platforms.

What is provided in the kit for installation

The kit contains rear CVD shafts, aluminium knuckle arms, spring steel wheel hexes, 6x13x5 bearings, M4x2.5x11 screw pins and set screws as supplied.

What are the main material choices and why

Hardened steel is used for axle sections to resist bending, while 6061 T6 aluminium is selected for knuckles to limit deformation and control weight. Spring steel hexes improve hub engagement under torque.

Are there setup checks after fitting the parts

After installation verify bearing seating, check set screw torque and confirm wheel clearance. Regular inspection will extend service life under heavy use.

How does the upgrade affect impact performance

The larger axle diameter and stronger materials reduce the chance of bending and improve stability on landings, delivering a more robust rear driveline for aggressive driving.
