LS Cast Steel Rocker Arm Set 1.7 Ratio 4.8L-6.2L

The LS Cast Steel Rocker Arm Set 1.7 Ratio 4.8L-6.2L from PRW Industries is designed for serious LS-series engine builders and high-performance enthusiasts seeking reliability under extreme conditions. This 16-piece rocker arm set is essential for achieving precise valve actuation in small-block and mid-size LS platforms, where stock components may limit performance potential.

Constructed from cast steel, these rocker arms feature a 1.7:1 mechanical advantage ratio, specifically designed for 4.8L through 6.2L LS displacement variants. The set includes eight millimeter pedestal mounts for secure attachment to the cylinder head, a roller-tip design that minimizes friction and wear, and silicone bronze bushings that enhance durability.

Professional engine shops, restoration specialists, and dedicated performance builders will find this rocker arm set particularly beneficial when upgrading from factory components or rebuilding older engines. The natural steel finish allows for immediate installation, although many builders opt to paint or ceramic-coat these components for aesthetic purposes.
