SBF S/S Roller R/A's - 1.6 Ratio 7/16 Stud

The SBF S/S Roller R/A's - 1.6 Ratio 7/16 Stud from PRW Industries represents a premium solution for high-performance engine builds requiring reliable valvetrain geometry. These rocker arms are engineered for users who demand precision-crafted components that deliver consistent valve lift across demanding driving conditions, from street performance to competitive racing applications. The full roller design eliminates friction losses inherent in traditional stamped rockers, making these arms ideal for builders seeking maximum efficiency and repeatability in complex engine combinations.

Built from stainless steel construction, the SBF S/S Roller R/A's feature a 1.6:1 ratio with precision 7/16-inch stud mounting for secure installation on compatible small-block Ford platforms. The full roller design minimizes valve train friction by replacing pad-on-shaft contact with sealed roller bearings, reducing parasitic power loss and heat generation. This engineering approach extends component life and improves overall engine efficiency—critical factors when tuning for maximum horsepower and reliability. The 1.6 ratio geometry provides optimal lift multiplication suitable for cam profiles ranging from mild performance to aggressive street-strip specifications.

Engine builders, machine shops, and performance enthusiasts working on small-block Ford platforms benefit most from these rocker arms, particularly when upgrading to performance cam profiles requiring reduced friction and improved valve control. Installation requires proper pushrod length verification and rocker arm geometry confirmation before operation. This 16-piece set covers complete valvetrain coverage on compatible small-block Ford engines, simplifying sourcing for full engine builds. Proper installation and regular maintenance ensure years of reliable service in both street and competition environments.
