GEN 5 LT Cam Bolt - VVT Phaser Solenoid VLV

The GEN 5 LT Cam Bolt – VVT Phaser Solenoid VLV by Brian Tooley Racing is a precision-engineered component designed for LS and LT-series engine builders seeking reliable variable valve timing control. This OEM-style replacement solenoid valve addresses the critical need for accurate phaser operation in modern direct-injection and naturally aspirated LT platforms. Whether you're diagnosing a P0016 or P0017 code, rebuilding a long-block, or optimizing cam timing stability on a high-performance build, this bolt serves as the backbone of your VVT system's hydraulic actuation.

As a cam bolt-integrated solenoid, this component regulates oil pressure delivery to the variable valve timing phaser, allowing the camshaft to advance and retard relative to the crankshaft position. The bolt assembly houses the solenoid valve internally, eliminating external plumbing complexity while maintaining tight hydraulic tolerances critical for engine performance and emissions control. Brian Tooley Racing's manufacturing ensures proper orifice sizing and spool geometry to prevent carbon buildup and sticky phaser conditions that plague factory units over time. Compact at 1.75 x 1.75 x 4 inches and weighing just 0.278 pounds, this bolt integrates seamlessly into the timing cover without modification to existing engine bay geometry or accessory drive layout.

Performance-minded builders and restoration shops benefit most from this solenoid, particularly when dealing with worn or problematic factory VVT systems on LS3, LT1, LT4, and 5.3L engines. Installation requires standard metric socket and torque wrench procedures; proper oil pressure and electrical harness connection are essential to avoid repeat failures. This component is ideal for street engines running stock ECU tuning, race platforms requiring VVT disable, or any build where OEM-level cam phasing reliability is non-negotiable. Verify your specific LT generation and intake manifold design before purchase to ensure correct fitment with your cam carrier and timing cover assembly.
