These Performance Quotient (PQX) drop-in rockers are preassembled for easy installation and cast from alloy steel with silicone-bronze bushings for standard OE oiling performance. Each rocker surface is tumbled with hand-polished toplines and logos. The system supports high-performance valve springs that exceed the limit of hydraulic lifters. When using solid lifter rollers, lash caps are required for final valve lash adjustment.
