CT1 Side Bell Bearing Alum Spool

The CT1 Side Bell Bearing Aluminum Spool from Diversified Machine is designed for high-performance drivetrain builds and competition applications. This spool is essential for applications requiring a solid connection between drive wheels, particularly in drag racing and other performance-focused scenarios.

Machined from lightweight aluminum alloy, the CT1 spool reduces unsprung weight while maintaining rigidity under load, which is crucial for managing high-horsepower outputs. Its side bell bearing design distributes forces across a larger contact surface, minimizing stress concentration and extending component lifespan during aggressive driving conditions.

Mechanics and fabricators building custom differentials, street rods, and track-prepared vehicles will find this Diversified Machine spool essential for applications requiring a locked differential. The compact footprint and featherweight construction make it compatible with tight differential housings while preserving overall vehicle weight distribution.
