SBC Ultra Gold R/A - 1.6 Ratio 7/16 Stud

The COMP Cams SBC Ultra Gold R/A with 1.6 Ratio and 7/16 Stud Mount is a full roller rocker arm designed for small block Chevy and GM V6 engine builds. This aluminum rocker arm delivers the precision valve actuation required in high-performance and racing applications, combining proven Ultra Gold ARC (Aluminum Roller Cam) technology with a durable gold anodized finish that resists corrosion while providing visual appeal in engine bays.

The 1.60 ratio specification increases valve lift by 60% relative to camshaft lobe lift, a critical factor in maximizing breathing efficiency at higher RPMs where naturally aspirated and forced-induction engines demand aggressive valve timing. Full roller design eliminates friction losses inherent to stamped steel arms, translating to more consistent, reliable valve control across extended engine operation. The 7/16-inch stud mount secures directly to the cylinder head, providing a rigid attachment point essential for maintaining valve clearance tolerances during high-load combustion cycles.

This rocker arm suits engine builders and enthusiasts upgrading small block platforms for increased performance—whether for street applications, dyno testing, or competition duty. The aluminum construction keeps overall engine weight minimal while the full roller bearing reduces wear on camshaft lobes, extending engine life under aggressive valve events. Each arm is sold individually, allowing builders to purchase complete sets matched to their specific pushrod length and valve train geometry requirements.

COMP Cams Ultra Gold components are established choices across street rods, drag racing, and circle-track applications where valve train reliability directly impacts engine durability and performance consistency. Installation requires proper valve lash adjustment and confirmation of pushrod length to prevent binding or excessive clearance—standard practice in small block cylinder head preparation.
