Technical Overview of the CAC-117

The 3Racing CAC-117 knuckle and rear hub set is manufactured to refine steering kinematics on the Kyosho Cactus 2WD, improving input-to-response characteristics and consistent rear axle alignment under corner loads.

Setup and Handling Impact

Engineered geometry delivers reduced steering latency and more repeatable wheel alignment through compression and rebound, enabling precise tuning of toe and steering ackerman for race day settings.

Materials and Service Considerations

Designed for frequent track use, these components balance stiffness and wear resistance to limit flex without compromising serviceability; inspect mounting hardware and bearings during routine maintenance.

The knuckle profile adjusts the effective kingpin inclination and steering arm length, which changes steering ratio and can tighten turn-in when combined with appropriate toe settings.
Start with baseline suspension settings and reduce front toe-in slightly to exploit crisper turn-in; verify camber under compression and adjust shocks to maintain tyre contact patch.
Inspect hub bearings and mounting fasteners after each race meeting and check for play in steering links. Replace worn bearings and torque bolts to spec to retain predictable geometry.
