Red Line Big Twin 20W50 PowerPack - Harley-Davidson Oil Change Kit

The Red Line Big Twin 20W50 PowerPack is a complete, pre-boxed oil-change kit for Harley-Davidson motorcycles with Evolution, Twin Cam and Milwaukee-Eight engines, combining the correct synthetic 20W-50 engine oil, primary chaincase oil and transmission oil tested together for compatibility. Each kit includes enough fluid for a full three-hole oil change. Note: 2007-up models with 96 cubic-inch and larger Twin Cam engines may require one additional bottle of Primary Chaincase Oil; check your capacity to avoid overfilling.
