The lifter has a chance to refill and adjust for bleed on the back side of the cam lobe as spring pressure subsides and the load is reduced. A lifter’s ability to react rapidly to changes in loading and maintain the desired plunger level is critical to optimum lifter performance. This is tied not only to lifter bleed down rates and oil viscosity, but also to also to the consistent function of the refill valve within the lifter. Clearances and surface finish within the lifter are the front-line defenders of performance. Hemi lifter tick is the inevitable result of poor manufacturing and inconsistent quality control.
Like McDonald's, Johnson Lifters has a secret sauce in the form of proprietary operations that ensure consistent lifter performance. One thing they can't control is the accuracy and quality of factory lifter bores, but they have an answer for that too. Just when you think getting the lifter in the bore and adjusting the valve is all that's needed, Johnson brings its unique technology to bear to ensure the top performance you've been waiting for. And no more Hemi Tick.. Outstanding.
