GM LS3/L92 Rocker Arm Set 1.7 Ratio w/8mm Bolt

The SHARP ROCKERS GM LS3/L92 Rocker Arm Set 1.7 Ratio with 8mm Bolt delivers OEM-quality valve actuation for LS-series engine builds. This complete set of 16 rocker arms is engineered for full-roller pedestal-mount design, offering the mechanical advantage and durability required in high-performance and stock-rebuild applications. The 1.7 ratio specification directly impacts valve lift geometry—delivering increased valve travel compared to lower-ratio designs while maintaining reliable contact with both pushrod and valve stem throughout the full engine cycle.

The aluminum construction with orange anodized finish provides corrosion resistance while reducing overall rotating mass—a critical consideration in performance applications where valve train inertia directly affects engine RPM ceiling and throttle response. The full-roller design eliminates the friction and wear associated with traditional rocker arm contact, extending service intervals and improving reliability under sustained high-RPM operation. The 8mm bolt specification ensures proper preload and security on the pedestal mount, critical for preventing rocker arm walk that can compromise valve timing accuracy and lead to catastrophic valve-to-piston contact in tightly-set clearance configurations.

This rocker arm set is purpose-built for LS3 and L92 engine platforms, making it essential for builders performing top-end rebuilds, performance cam swaps, or complete engine overhauls. Whether restoring a stock configuration or supporting upgraded valvetrain components, this set provides the precision fitment and mechanical integrity that prevent costly failure modes in street, track, or marine applications. The complete 16-piece set eliminates individual sourcing and ensures matched geometry across all cylinders.
