Synthetic gear oil
California based Maxima Racing Oils’ 100 percent synthetic gear oil has been specifically formulated for high performance V-twin transmissions and chain cases.
Designed for use in all 1984 and newer Harley models with wet diaphragm spring clutches, this high strength film oil is said to provide excellent protection against shock loads and wear and also offers smooth shifting under peak loads and rpms.
The robust formula resists mechanical shearing and heat breakdown and protects gears from wear and deposits for trouble-free operation.
Maxima’s Syn Primary was first introduced around 20 years ago and developed specifically in response to the high heat seen in H-D engines. This made Maxima one of the first oil manufacturers to introduce a 100% synthetic lubricant for Harleys. In 2015 Syn Primary was re-introduced and given a face lift to match the rest of Maxima’s newly formed V-twin line of products.
