Valve Spring

The Mopar valve spring kit is engineered as a direct replacement component for 5.7L and 6.4L HEMI V8 engines. These damperless springs come in a set that includes a new 1mm valve seat, providing essential support for your valvetrain system. Compatibility is specific to engine production dates. Parts with the 1mm valve seat are used on engines produced before January 28, 2010. Engines produced on or after this date utilize a 2mm valve seat configuration. This component is compatible with a wide range of HEMI variants, including the 5.7L MDS VVT (with or without BSG/CNG) and the 6.4L heavy-duty MDS HEMI. It is also compatible with vehicles equipped with the 8HP75-LCV 8-speed automatic transmission. As a genuine OEM part, this kit is manufactured to stringent factory standards to ensure reliability and optimal engine performance. Note that these springs are intended for specific valvetrain configurations; please verify your engine production date and valve seat requirements before installation.
