Suspension Springs
PAC Racing Suspension Springs is a newer product line for PAC Racing Springs. With PAC success in valve springs we are pushing the envelope for suspension springs by introducing valve spring processing into suspension springs. The high demands of racing engines and valve springs will not allow for large tolerances, high load loss rates, or premature spring failure.
PAC Racing Springs has taken the valve spring philosophy to suspension springs. Through our extensive testing on Servo Hydraulic test machines, which evaluates fatigue life, load loss, free length loss, and travel, we have been able to develop new methods previously unused in suspension spring manufacturing. With these successes we have been able to help our customers excel in suspension setup and reliability.
PAC Racing Suspension Springs have been able to maintain excellence in:
- Parts conforming to the strictest rule book requirements
- Maintain spring load and rate required for your application
- Exceeding spring travel requirements and pushing for more spring travel
- Consistent rate curves and loads. We use the same load check equipment as officials.
- SUPERIOR FATIGUE LIFE
