Phaser Lockout

GM Gen V LT Engines

Eliminates VVT Function (0 Cam° Retard)

CNC-Machined Billet Block

Max Camshaft Support with Stable Timing Events

The BTR-VVT-GENV-LO phaser lockout is engineered for Gen V LT series engines (including LT1, LT4, and compatible L83/L86 platforms) to completely disable variable valve timing (VVT), locking the intake cam phaser at 0 camshaft degrees of retard. This allows high-duration camshafts and elevated load environments to operate with secure, fixed timing events.

Brian Tooley Racing BTR-VVT-GENV-LO Includes:

One billet phaser lockout block (0 cam° retard)

Brian Tooley Racing BTR-VVT-GENV-LO Features:

Locks intake cam phaser at 0 camshaft degrees of retard for true fixed-timing operation
CNC-machined billet aluminum for optimal durability under race and high-boost conditions
Eliminates VVT movement to maximize piston-to-valve clearance and reduce timing variability
Ideal for large-duration camshafts, high cylinder pressures, turbo/supercharged or nitrous-fed applications
Requires correct phaser tool and installation procedure to ensure secure installation and performance integrity

Brian Tooley Racing BTR-VVT-GENV-LO Notes:

Sold individually; match quantity to number of cam phasers being locked
Confirm engine configuration (Gen V LT family) and VVT phaser compatibility before purchase
After installation, calibration changes required to reflect fixed-timing cam operation and eliminated VVT range
