We use only the very best speed parts on our builds and no one makes better ball joints than Howe Racing. We service the `Cuda's first set of upper ball joints with some Schaeffer's 238 Ultra Supreme heavy duty grease so they are ready to swap out the current second set at a moments notice. We have a third brand new set for the 73 Challenger build.
Forgot to mention to lube the threads on the cap and housing! Had to go back later and fix that haha!
