It's a white ointment specifically designed to lubricate racing car chains. Thanks to a formula based on pure AW/EP additives, the lit_LatnUL® Chain Lube Factory Line reduces rolling resistance and thus saves up to one horsepower and more. Protects against wear and is resistant to extreme pressure. Suitable for O-ring, X-ring and Z-ring chains. Before this, clean the chain with the Chain Clean. Crush the vial and spray the entire length of the chain. Let it dry. In order to achieve optimum performance, the chain must be stained before each race.
