The unique design allows the rings to maintain consistent pressure under high heat conditions and to conform to worn or out of round cylinder bores. Standard tension oil ring assemblies are engineered to provide maximum oil control for virtually all engines. They maintain consistant contact with the cylinder wall and provide an excellent drainback path for the removed oil. Low tension Speed-Pro oil rings are offered for increased horsepower potential. They reduce internal engine friction while affording positive oil control in racing applications.
Oil rings with further reductions in tension are available for use with crankcase vacuum systems.
Pro-Series Ring Sets Professional racing trends have focused on lowering ring thickness and weight, and on reducing ring tension in an effort to minimize cylinder wall drag. Pro-Series ring sets are designed for serious racing, and offer several features which maximize horsepower potential. Pro-Series sets incorporate reduced radial wall thickness top and second rings for lower tension and enhanced sealing. They also include a very low tension, thin profile version of the SS-50, which includes a wire latch mechanism to simplify installation. Radial Thickness All of the rings in the Speed-Pro line meet original equipment dimensions specifications for proper fit and easy installation.
