These Chrysler Hemi springs come with shims which are ONLY needed for 6.1L applications on the intake side in order to achieve the correct installed height. P/N 221431 also includes a set of piloting rings that install over the factory “Top Hat” integral valve seal to properly locate the ID of the spring on early 5.7L (thru 2008) and 6.1L applications.
