Product Description
Texas Speed Gen V+ VVT Phaser 0 Degree Limiter Lockout Block
Fits Select 2019+ Gen V & Gen V+ GM LT Engines | Performance Camshaft Applications
The Texas Speed Gen V+ VVT Phaser 0 Degree Limiter Lockout Block is designed to fully limit variable valve timing on select Gen V and Gen V+ GM LT engines, locking the camshaft phaser at 0 degrees. This allows increased piston-to-valve clearance when running aggressive aftermarket camshafts with significantly more duration than stock. CNC machined from high-strength steel, this limiter provides the durability and precision required for high-performance street, track, and racing applications where VVT control must be eliminated for consistent valve timing.
Key Features & Benefits
- Locks VVT at 0 Degrees: Completely eliminates cam phaser movement, ensuring fixed cam timing for maximum piston-to-valve clearance on high-duration camshaft setups.
- Enables Aggressive Camshaft Profiles: Frees up critical piston-to-valve clearance, allowing the use of much larger-than-stock camshafts in Gen V+ LT engines.
- High-Strength CNC Machined Steel: Precision machined from durable steel to withstand high RPM operation and extreme valvetrain loads.
- Consistent Valve Timing: Eliminates VVT variability, delivering predictable cam timing for tuning stability and repeatable performance.
- Professional Installation Required: Requires a specialized phaser tool kit for proper installation and secure lockout.
