Got a 2009+ 5.7 HEMI and need more valve spring, but want to keep your OEM hardware and save some money? We've got your springs! Great to use when upgrading the cam in your 2009+ 5.7 HEMI application. Max valve lift is .625". This kit uses the venerable 68277306AA Mopar valve spring, but in a convenient 16 spring kit!
