HRATF11A01 - Aluminum Differential Carrier Case - BLX 3S 4S

CNC‑machined aluminum differential carrier case designed to replace a molded stock unit in 1/10 scale RC trucks and buggies running BLX 3S/4S power systems. The rigid housing supports internal differential gears more securely, helping maintain correct gear alignment and reducing deformation under high torque loads. Precision cast and milled surfaces improve structural integrity and drivetrain efficiency.

• CNC machined aluminum construction increases rigidity and strength compared with stock plastic carrier cases

• precision milled bearing seats maintain accurate differential gear alignment under load

• reinforced walls help resist flex and deformation during hard acceleration and high‑torque conditions

• designed for compatibility with BLX 3S/4S drivetrains using standard differential housings

• black anodized finish resists corrosion and everyday wear

• helps maintain consistent gearbox geometry for smoother power transfer

• includes hardware for straightforward carrier replacement
