Tilton Engineering 66.013 HGG 7.25″ OT-II Metallic Racing Clutches (POT Type) are engineered for optimal performance in road racing, circle track, open wheel, and formula racing environments. These clutches are constructed to deliver a low moment-of-inertia and high torque capacity, ensuring reliability in demanding racing conditions.
The 7.25″ metallic clutches are predominantly used in road racing and circle track racing due to their robust performance characteristics. The clutches are available in two specific configurations: one designed for step-type flywheels and another for pot-type (no-step) flywheels.
Step-type flywheels feature a .100″ step, facilitating contact with the clutch's friction material, resulting in a .100″ height differential between the bottom friction disc and the terminus of the clutch cover legs. In contrast, pot-type flywheels lack this step, allowing the friction disc and clutch cover legs to be flush.
Tilton's metallic clutches offer the choice between a High Ratio or Ultra-High Ratio pressure plate. The High Ratio pressure plate delivers high clamp load across an extensive wear range, while the Ultra-High Ratio pressure plate increases clamp load by 20% and enhances diaphragm spring travel for superior modulation. The High Ratio pressure plate maintains a relatively consistent clamp load up to .030″ (76mm) of wear. Conversely, the Ultra-High Ratio pressure plates provide a higher initial clamp load at an accelerated wear rate.
Key technical features:
- Standard pressure plate ratio for 7.25″ metallic clutches
- Minimal release travel enabling rapid engagement and shifting
- Consistent clamp load curve for extended wear range
- 20% increased release travel compared to High Ratio for enhanced modulation
- 20% higher clamp load than High Ratio for elevated peak torque capacity
- Faster clamp load reduction with wear compared to High Ratio
