High Performance Valve Spring Kit for GM LT – # VSK46697T-LT

BUILT FOR THE LT POWER YOU'RE CHASING

MORE CAM. MORE RPM. MORE PEFORMANCE

When you're upgrading an LT engine, more power means more demand on the valvetrain. The Melling VSK46697T-LT High Performance Valve Spring Kit was engineered to help your valvetrain keep up with aggressive cam profiles, higher RPM, and the performance goals you've built your combination around.

BUILT TO CONTROL THE RPM

Melling started with its proven .660" lift dual LS valve spring and gave it a complete redesign.

The reduced-mass spring design helps maintain valve control as RPM increases, providing the stability performance LT builds need when the engine is pushed to its limits. Whether you're chasing more horsepower, a bigger cam, or peak performance on the street or track, the VSK46697T-LT is designed to help your valvetrain keep up.

STRENGTH WHERE IT MATTERS

Performance parts are only as good as the process behind them.

That’s why Melling manufactures our own springs- so the quality of the spring in the box is worthy of the Melling brand. The VSK46697T-LT features CNC-coiled spring wire, in-house heat treatment, multi-level shot peening, and proprietary polishing processes designed to deliver consistent spring performance and long-term durability under demanding conditions.

Translation: Built to handle repeated abuse, not just look good on paper.

MORE THAN A BOX OF SPRINGS

A valvetrain is a system.

That's why the VSK46697T-LT includes lightweight titanium retainers, premium Viton™ valve seals, steel valve locks, and black oxide-coated chromoly seats and shims.

Every component is selected to work together, helping eliminate guesswork when putting together your build.

BUILT FOR LT ENTHUSIASTS

Perfect for:

✅ Camshaft upgrades
✅ Street performance builds
✅ Street/strip cars
✅ Performance trucks
✅ High-RPM LT combinations

Whether you're chasing quicker ETs, stronger acceleration, or a more capable weekend warrior, the VSK46697T-LT is designed to support the performance you're building toward.
