Key Features & Benefits
- Gen V LT Conical Spring Design: BTR developed this conical valve spring kit specifically for compatible Gen V LT engines. The conical configuration provides an alternative to a dual valve spring package when the selected camshaft profile does not require dual springs.
- Supports Up to .650-Inch Lift: Designed to accommodate camshafts with valve lift measuring up to .650 inch. This operating range makes SK013 suitable for numerous compatible Gen V LT camshaft upgrades without automatically requiring a dual-spring configuration.
- Improved High-RPM Stability: The conical springs are designed to provide greater valvetrain stability at elevated engine speeds. This helps support consistent valve control in applicable performance camshaft combinations while maintaining the specified spring pressures and operating dimensions.
- Uses Factory Valve Spring Retainers: The SK013 kit is designed to operate with the stock Gen V LT valve spring retainers. Retaining the factory retainers reduces the number of additional valvetrain components required for the supported spring installation.
- Complete Supporting Hardware: In addition to 16 SP014-1 conical valve springs, the kit supplies the corresponding spring locators, valve stem seals and valve locks. These components provide the supporting parts specified for the SK013 spring configuration.
