RED LINE SYNTHETIC OIL - 42804 - V-Twin Transmission Oil with Shockproof - 1 US quart
The RED LINE SYNTHETIC OIL 42804 is a shock replacement built for riders who want their machine's suspension performing correctly without paying dealer prices. Dampens transmission noise (reducing the notorious shifting clunk found in these gearboxes), dramatically reduces temperature, provides thicker oil films between gear teeth and resists throw-off. Same fluid as our unique Heavy ShockProof® Gear Oil, which means proper damping, correct ride height, and handling characteristics that match what the manufacturer engineered. For all H-D® transmissions including with M8 engines, Evolution engines, Twin Cam engines and latest 6-speed Cruise Drive.. Engineered for specific vehicle applications, the 42804 takes the fitment guesswork out. Shock replacement is one of the most immediately noticeable improvements you can make. Sold individually.
