GM LS1 Ultra Gold R/A's - 1.82 Ratio

The GM LS1 Ultra Gold R/A's with 1.82 ratio from COMP CAMS represent the pinnacle of rocker arm engineering for serious LS engine builders and performance enthusiasts. Designed specifically for GM LS-series platforms, this complete 16-piece set delivers the reliability and precision needed for high-revving applications, whether you're building a street machine, track car, or all-out competition engine. These pedestal-mount rocker arms are engineered to handle the demands of modified LS powerplants where valve train stability and durability are non-negotiable.

The 1.82 mechanical advantage ratio enhances valve lift geometry, promoting aggressive cam profiles and improved cylinder head flow characteristics across the RPM band. Constructed from lightweight aluminum and finished in gold anodizing for both durability and visual appeal, these Ultra Gold rocker arms feature full roller design that minimizes friction losses and extends component lifespan under extreme operating conditions. The roller bearing construction ensures consistent valve actuation with virtually zero deflection, critical when running high-lift cams and aggressive valve springs that demand precision valve timing and consistent opening/closing events.

LS engine owners pursuing serious performance modifications—from naturally aspirated builds maximizing cylinder head potential to forced induction applications—will appreciate the engineering integrity and proven track record of COMP CAMS' Ultra Gold line. Installation onto factory or aftermarket pedestal-mount cylinder heads is straightforward, and the complete 16-piece set ensures you have matching arms for all intake and exhaust positions. Whether upgrading from stock rocker arms or replacing worn components in a high-mileage build, these precision-manufactured pieces deliver the valve train control necessary to unlock the full potential of your LS platform.
