I have always PROMOTED Freely Redline...
I know that the ShockProof Heavy is designed For NO Metal To Metal contact...
Using others JUST to see IF they work as well is a Waste OF time in my Book...:small3d023:
Harley FINALLY says to change out the tranny at 20,000 miles...
That said :::: IF your choice is not the best, 20,000 miles is WEAR that should not have happened JUST for trying to SEE...
Take My word AND Many Others who use Redline Shockproof.... Heavy, Light Or the lighter product they make...
Redline is the Best By Far.:rofl
