the ZeroRC SR-OP-5 (specifically SR-OP-5-2) is the high-precision Metal Front Axle/CVD Set designed for the All-Wheel Drive (AWD) version of the RW00-SR chassis.
 
Product Details:
 
this component is essential for transmitting power to the front wheels in an AWD configuration:
Design: High-angle Constant Velocity Drive (CVD) shafts that prevent "chatter" or binding when steering at extreme angles.
Material: Constructed from high-strength steel to handle the torque of the front drivetrain.
Compatibility: Specifically engineered to fit within the SR-OP-4-2 (AWD Metal Knuckles). 
 
Configuration Variants:
 
The SR-OP-5 designation is split into two versions based on the drivetrain: 
SR-OP-5-1: Metal Front Axle for RWD (MR) layouts (non-driven, simple axle stub).
SR-OP-5-2: Metal Front Drive Axle for AWD layouts (includes the universal joint and shaft for power delivery).
