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.

  • Complete Shaft-Mount Conversion – Upgrade your square-port LS7 heads with 8 hardened shafts, 32 floating bronze bushings, and 33 snap rings for rock-solid rocker control.
  • Square-Port LS7 Fitment – Designed exclusively for 7.0 L LS7 engines (2006–2013 Z06 Corvette, 2014–2015 Z28 Camaro) with cathedral-port variants not supported.
  • Minimizes Rocker Deflection – Shaft system locks rocker geometry and eliminates side-to-side play for ultra-consistent actuation.
  • Full-Floating Bronze Bushing System – Bronze bushings provide superior rotational stability, low friction, and extended durability in high-load environments.
  • Engineered for Abuse – Perfect for high-horsepower street, strip, marine setups, or forced-induction engines—race-rig tested and built tough.
