CHE LS7 Shaft-Mount Trunnion Kit (CHE-3720-SM) | Reinforced Rocker Shaft Upgrade for 7.0L LS7 Z06/Z28 (2006-2015) | Ultimate Valvetrain Stability

Dominate high-RPM LS7 builds with elite valvetrain control using the CHE Precision LS7 Shaft-Mount Trunnion Kit (CHE‑3720‑SM). Engineered for square-port 7.0 L LS7 heads in 2006–2013 Z06 Corvettes and 2014–2015 Z28 Camaros, this comprehensive kit includes 8 hardened shafts, 32 full-floating bronze bushings, and 33 snap rings. By converting factory rocker setups into shaft-mounted systems, it virtually eliminates deflection, locks in valve timing consistency, and isolates harmonics on a per-cylinder basis. Built from premium materials and precision-machined, this kit stands strong under boosted, track, marine, and pro-street conditions. Rocker arms not included—serious builds only.
