3V Performance Gen V LT L83/L86 Beehive Valve Spring Kit, 10° Hardware | 3VP-GENV1516MLKIT

Gen V LT Beehive Valve Spring Package with 10° Hardware

Build your Gen V LT valvetrain around PSI LS1516ML Max Life beehive springs and a matched 10-degree hardened chromoly retainer and hardened lock system. Designed for performance camshaft applications, this 3V Performance package combines beehive springs with the retainers, locks, locators and valve-stem seals listed below.

The lightweight beehive design reduces valvetrain mass. The springs support up to .670-inch valve lift when properly installed and verified. Actual allowable lift depends on your measured clearances and installed height.

Package Includes

• 16 PSI LS1516ML Max Life beehive valve springs
• 16 R502-16 hardened chromoly 10-degree retainers
• 32 3VP-L011 premium hardened 10-degree valve locks
• 16 LVS-1700 valve-stem seals
• 16 3VP-LBH60520 hardened beehive valve-spring locators

Installation Requirements

This is a precision performance valvetrain package. All clearances and installed heights must be measured during installation.

Before assembly:

• Thoroughly clean every component and mating surface.
• Measure the installed height of all 16 valve springs.
• Target a 1.800-inch installed height unless otherwise directed by the camshaft manufacturer.
• Add the appropriate hardened shims beneath the spring locator when necessary to obtain the required installed height and spring pressure.
• Verify actual coil-bind clearance at maximum valve lift.
• Verify retainer-to-valve-seal and retainer-to-valve-guide clearance.
• Apply a thin film of clean engine oil or assembly lubricant to all mating surfaces.
• Confirm that the final seat and open pressures meet the camshaft manufacturer’s requirements.

Important Installation Notice

The .670-inch rating represents the spring’s maximum advertised lift capability. Actual allowable valve lift depends on measured installed height, actual coil-bind height and required safety clearance.

Never rely on the advertised maximum-lift rating alone. Failure to verify installed height, spring pressure, coil-bind clearance and retainer clearance can result in severe valvetrain or engine damage.

Professional installation is strongly recommended.
