HRSTRF41 Hardened S2 Steel Outdrive Cups 4-Tec 2.0 3.0

Outdrive cups machined from hardened S2 steel and engineered to replace the stock plastic components in the front and rear drivetrains of 4-TEC 2.0 and 3.0 chassis to improve strength and longevity. The robust metal construction resists wear, bending, and deformation under high torque loads that can cause fatigue in plastic parts, especially with brushless power systems and aggressive driving. Precision machined bores and surfaces support smoother rotation and reduced drivetrain lash while maintaining proper geometry with existing CV joints and driveshafts. Intended as direct replacements that use the original hardware and mounting interfaces for straightforward installation.

• Hardened S2 steel construction for superior strength and wear resistance.
• Designed for front and rear outdrive cup applications in 4-TEC 2.0/3.0 drivetrain systems.
• Precision machined bores and surfaces promote smooth power transfer.
• Resists deformation and bending under high torque compared with plastic parts.
• Helps reduce drivetrain lash and improve component life.
• Direct replacement fit using existing hardware and geometry.
• Suitable for aggressive driving and high-load conditions.
