The Texas Speed Gen V LT Dual Valve Spring Kit (.660 Lift) is engineered to provide the valve control, durability, and reliability required for upgraded camshaft and performance valvetrain applications in GM Gen V LT engines. Designed around premium PAC Racing dual valve springs and paired with lightweight titanium retainers, this kit supports aggressive cam profiles while maintaining stable valve motion at elevated RPM. Ideal for LT1, L83, and L86 5.3L and 6.2L engines, this spring package is a proven solution for naturally aspirated, boosted, and performance street builds that demand precise valve control and long-term reliability.

  • Valve Spring Specs for Gen V LT Engines: Dual PAC valve springs rated for up to .660" valve lift with approximately 155 lbs seat pressure and 400+ lbs open pressure, designed to maintain valve control and prevent float in performance camshaft applications.
  • Designed for LT1, L83 & L86 Platforms: Engineered specifically for GM Gen V 5.3L and 6.2L LT engines, providing correct installed height, spring rate, and compatibility for performance valvetrain upgrades.
  • Includes Lightweight Titanium Retainers: Titanium retainers reduce valvetrain mass, improve RPM stability, and enhance durability when paired with higher-lift camshafts and aggressive valve motion.
  • Supports Aggressive Camshaft Profiles: Ideal for aftermarket cam upgrades, boosted setups, and high-RPM street or strip builds requiring increased spring pressure and reliable valve control.
  • Texas Speed Proven Performance: Built using high-quality PAC Racing components and trusted Texas Speed engineering, delivering consistent performance and reliability for demanding Gen V LT builds.
