New Center Section FS LW 650 Ratio 31 Spline

The New Center Section FS LW 650 Ratio 31 Spline is a lightweight differential center section designed for serious drivetrain builders and performance enthusiasts. It aims to reduce unsprung weight while maintaining durability in high-torque applications, making it ideal for street and track use.

This center section features advanced manufacturing techniques and optimized material selection to reduce rotating mass compared to factory components. The 650 ratio designation indicates the gear set configuration, while the 31-spline interface ensures secure engagement with compatible driveshafts and axle shafts.

Ideal for drag racing, autocross, or dedicated track platforms, this full-spool design provides consistent power delivery to both wheels under acceleration. It is particularly beneficial for builders upgrading third-generation F-body Camaros, Firebirds, and similar vehicles that require enhanced performance and weight reduction.
