Joe Gibbs Driven assembly grease is used by Joe Gibbs Racing during the assembly of every engine. It provides proven extreme-pressure protection for heavily loaded parts during initial break-in. The unique formula completely dissolves in oil. Joe Gibbs Driven assembly grease can be used to prelube cams and lifters, and applying it to the piston ring land prevents micro welding during initial engine break-in. It can also be used on wrist pins, distributor gears, pushrods, and valve retainers.
