CT1 Spool Shim Kit

The CT1 Spool Shim Kit by Diversified Machine is a precision differential tuning component designed for automotive enthusiasts and mechanics seeking improved vehicle handling and power delivery. This kit is specifically built for manual transmission and limited-slip differential applications, making it ideal for those upgrading their vehicles for track use or performance driving.

The shim kit addresses the critical gap between stock spool geometry and aggressive drivetrain setups. By fine-tuning the internal geometry of your differential's spool mechanism, it helps control load distribution across the drive wheels, enhancing performance during acceleration and cornering. The engineered shim stack is precision-machined to ensure consistent engagement and minimize issues like chatter or binding.

Ideal for mechanics and tuners, the CT1 Spool Shim Kit is essential for those running significant power upgrades or competing in autocross and road racing environments. Its ability to adjust spool preload allows for tighter control over torque biasing, which is crucial for reducing inside-wheel slip during hard cornering while maintaining smooth power application under normal driving conditions.
