The ZeroRC RW-OP-17 (often labeled with SP.SPEC in professional tier listings) is the Metal (Aluminum) Type-2 Front Knuckle Set designed for the RW00 series of 1/24 drift chassis. 
 
Key Specifications & Performance:
 
As a critical steering component, the Type-2 knuckles focus on precision and extreme steering angles: 
Material: CNC-machined from high-grade aluminum, typically finished in the signature ZeroRC Purple anodizing.
Design Focus: Specifically engineered to eliminate "slop" (play) in the front suspension, providing a more direct and intuitive steering feel for high-angle drifting.
Bearing Integration: Features precision-machined bearing holes that optimize suspension movement when paired with the lower control arms.
Aesthetic & Realism: Designed with a slim profile to fit behind scale 1/24 wheel rims while often including mounting points for decorative brake disc sets like the RW-OP-19
