The Texas Speed Gen V +0 degree phaser limiter block is engineered for 2019 and newer Gen V LT engines to mechanically limit variable valve timing movement while retaining proper cam phaser operation. Designed for L84, L87, and L8T engines, this +0 degree limiter prevents excessive cam advance or retard that can cause valvetrain instability in performance and reliability-focused builds. Ideal for camshaft upgrades, engine rebuilds, and durability-driven applications, this lockout block provides consistent cam timing behavior without fully disabling VVT functionality. Precision manufactured by Texas Speed, it is a proven solution for maintaining stable engine operation when factory phaser movement is no longer desired.
