Front Seal for CT1 Seal Plate

The Front Seal for CT1 Seal Plate (RRC-1002) by Diversified Machine is a precision engineered PTFE and steel lower shaft coupler seal designed for the CT1 Quick Change Rear End system. This component is critical for maintaining shaft integrity and preventing fluid leakage in high-performance drivetrain applications where consistent coupling performance is essential under extreme operating conditions.

Constructed from PTFE (polytetrafluoroethylene) paired with steel, this seal combines low-friction polymer characteristics with steel's structural stability. The PTFE material resists wear and chemical degradation, while the steel backing provides the necessary rigidity to handle radial and axial loads without deformation. Weighing just 0.13 pounds and measuring 3.45 x 1 x 3.5 inches, the compact profile integrates seamlessly into CT1 quick-change systems without adding unnecessary bulk. This seal addresses a common point of failure in quick-change differentials—the coupler interface—where standard elastomers can deteriorate under sustained load and temperature cycling.

The RRC-1002 is specified for operators and technicians working with Diversified Machine CT1 rear ends in high-output engine applications, including street performance builds, drag racing platforms, and sustained-duty vehicles where differential fluid retention and coupling reliability cannot be compromised. Replacement or preventive maintenance of the coupler seal extends drivetrain service life and prevents the secondary damage that results from fluid loss during operation.

Quick-change rear end systems have become standard in performance and racing applications due to their efficiency in gear ratio changes. The seal components that support these systems require OEM-specification parts to maintain the engineering tolerances the differential relies on. Diversified Machine seals are matched to CT1 geometry, ensuring proper compression, alignment, and performance when installed correctly.
