Description Crankshaft Bearings plastic cage Stage6 R/T with Oil SealsEspecially in high-performance engines, the quality of crankshaft bearings and oil seals is crucial. Stage6 has upgraded their kits by pairing their already top-tier SKF bearings with bold orange FKM oil seals from the Stage6 R/T line – great look, even better performance.Note, for Peugeot vertical Euro 1 before 2004Crankshaft Bearing TypesThe bearings are available in 2 versions- Polymer cage – designed for racing use. The polymer version offers more flexibility and reduced friction compared to metal cages. - Metal cage – built for daily street use. More durable than the polymer version, ideal for long-term loads.Both types are SKF-approved for speeds up to 20,000 RPM. Proper lubrication and correct installation are essential for longevity.The advantages with the polymer-plastic version compared to metal cages are increased elasticity and reduced friction. We personally this type of bearing for racing engines, but you'll have to pay some attention to carburetor and ignition settings, as the bearings may only be permanently heated to a maximum of 120° to prevent damage to the plastic cage. Attention! The polymer cage version should only be installed on engines without a catalytic converter!Please pay attention when installing the bearings: The half-open side must face the crankshaft webs.The newly developed orange FKM oil seals are produced using cutting-edge technology. Compared to older models, they offer longer lifespan and reduced friction for better overall engine efficiency.Bearings and Seals Set:2x crankshaft bearing SKF C4 20x52x12mm polymer cage1x oil seal FKM 20x30x5 (6,5) mm1x oil seal FKM 15,6x25,5x7mm Questions about the product
