CHE LS7 Shaft-Mount Trunnion Kit (CHE-3720-SM) with Rocker Arm Bolts | Fits Square-Port 7.0L GM Engines | 2006-2013 Z06 Corvette & 2014-2015 Camaro Z28 LS7 Engines

The CHE LS7 Shaft‑Mount Trunnion Kit (CHE‑3720‑SM) offers a precision-engineered valvetrain upgrade for square-port LS7 7.0L engines found in 2006–2013 Z06 Corvettes and 2014–2015 Camaro Z28s. This kit includes eight hardened steel shafts, thirty-two floating bronze bushings, thirty-three snap rings, and a full set of LS7-specific rocker arm bolts—providing everything you need for a secure and robust shaft-mount conversion. The shaft-mounted design locks in valvetrain geometry and eliminates rocker deflection, isolating harmonics per cylinder for consistently precise valve control—even under high RPM, forced induction, or marine environments. Machined in the USA with high-quality components, this upgrade is ideal for demanding performance builds. Rocker arms are not included.

• Complete Shaft‑Mount Conversion with Bolts – Includes 8 shafts, 32 bronze bushings, 33 snap rings, and torque‑specified LS7 rocker bolts for a seamless, all-in-one installation.
• Enhanced Valvetrain Precision – Floating bushing design isolates harmonics and prevents deflection, improving valve timing stability even at high RPM or under heavy load.
• Engineered for LS7 Square‑Port Heads – Designed specifically for 2006–2013 Z06 Corvette and 2014–2015 Camaro Z28 square-port LS7 engines for a factory-correct fit.
• Durable Construction for Extreme Conditions – Manufactured using high-strength, precision-machined materials capable of withstanding supercharged, drag, marine, and other high-demand applications.
• Floating Bronze Bushing Design – Ensures smooth, consistent rocker movement, reducing wear and enhancing valvetrain longevity during aggressive driving.
