Got loose chain? The Block Mount, Sprocket Equipped, Universal Fit, RCF Chain Tensioner is what you need! Get this bad boy in 2 chain sizes, 35 or 40,41,420 , and space it out from 3 to 13 inches depending on what you need. Plus the lightning bolt is sure to add a couple horsepower (Not yet tested), and it makes your next build look awesome, but for real, lightning bolt!

Also, we’ll throw in the mounting hardware for ya! Billet side covers will require a different thread size.
