We go over how to select pushrod length to set desired lifter preload. Improper lifter preload can create a multitude of valve train issues, such as lifter failure, excessive component wear, and improper detonation etc. Save your engine and your sanity, and do it right the first time.

Make sure to check what your target preload is for your selected lifters and keep your build moving! Like and subscribe guys, thanks!
