Key Features & Benefits
- LS7-Specific Drop-In Package: Designed for factory LS7 cylinder heads on the listed 7.0L Corvette Z06 and Camaro Z28 applications. The kit brings together the dual springs and supporting components needed for this stock-guide-diameter, factory-rocker-body configuration.
- Polished .660-Inch Dual Springs: Includes polished dual valve springs with a .660-inch lift rating. Specified spring pressures at three heights provide useful reference points when selecting components for an LS7 valvetrain upgrade or replacing an existing spring package.
- Titanium Retainers Included: Supplied with titanium valve spring retainers as part of the Michigan Motorsports LS7 spring package. Including the retainers and valve locks with the springs simplifies gathering the supporting hardware for the intended cylinder-head configuration.
- Stock-Diameter Guide Compatibility: The included spring locators are intended for stock LS7 valve guides. The kit also accommodates aftermarket guides with the stock diameter, supporting factory LS7 heads that retain the original guide dimensions during cylinder-head service.
- LS7 Shims and Valve Seals: Includes .030-inch shims for LS7 heads along with valve stem seals. These components round out the spring package, providing the specified shims and seals together with the springs, retainers, locators and locks.
