VALVE SPRING - Part Number 91-521
Crane Cam's is about to revolutinize the valve spring market with their Thermo-Cool Coating that not only reduces friction but also eliminates hot spots in spring coils. Thermo-Cool Springs generate less heat because of less friction. It also evenly dispenses any heat built up, eliminating oil burn-off. This means significantly less pressure fade and cleaner, cooler oil in your engine. The new Thermo-Cool coated spring for Shovel has shown almost unbelievable results in both test and actual racing applications. The friction reducing quality of the coated springs is only one benefit. A bigger advantage to the coated spring is its ability to dispense heat quicker than an uncoated one. This helps to eliminate hot spots in the spring coil which cause weakness and ultimate pressure loss. Cooler springs also mean less oil burn-off helping to reduce contamination and oil temperature.
