Melling VSK46694T High Performance Dual Valve Spring Kit with Titanium Retainers for GM LS Engines

The Melling VSK46694T is a complete high-performance valve spring kit engineered for GM Gen III and Gen IV LS engines. Featuring an ovate beehive spring design, this kit delivers superior valvetrain stability, reduces valve float risk, and exceeds OEM spring pressure specifications — making it an ideal upgrade for street performance, circle track, and drag race applications.

The titanium valve spring retainers set this kit apart from the standard VSK46694. Lightweight titanium construction reduces reciprocating valvetrain mass, allowing the engine to rev more freely while maintaining reliable spring control under high-RPM conditions and aggressive camshaft profiles.
