Rev Kit (LS1)  E-mail this product to a friend

We recommend Rev Kit's for all hydraulic roller forced induction applications. They will dramatically improve high rpm stability which results in more horsepower and longer service life for your valvetrain. The function of the Rev Kit is to preload the lifters against the camshaft which reduces the energy required by the valvespring to close the valve. This is extremely important when boost pressure is on top of the valve trying to keep it open.

The Rev Kit installs above the lifters and replaces the OEM plastic lifter guide.
