About This Product
For the early Twin Cam bagger owner, this MCS Big Oil kit offers a modern synthetic upgrade. It fits 1999 to 2006 FLT and Touring models and features six liters of Vspec 3-in-1 full synthetic 20W50 oil. This versatile blend is designed for use in the engine, primary, and transmission, making it a convenient all-in-one solution that meets JASO MA/2 specifications. The kit includes a chrome oil filter, which replaces OEM 63798-99A, plus a 34906-85D inspection cover gasket and a 11105 drain plug O-ring. Using full synthetic oil provides superior thermal stability and protection for high-output engines, making this kit perfect for a thorough service interval or preparing for long-term storage. This set is sold as a kit.
Manufacturer part number: 985825.
