Pro-Comp 1.4 Ratio Forged Rocker Assembly

The SCAT Pro-Comp 765 forged 4340 chromoly rocker assembly is engineered to enhance the performance of your Aircooled VW engine. With a 1.4 ratio, these rockers effectively increase total valve lift without necessitating a camshaft change, allowing for improved airflow and potential horsepower gains while maintaining streetability. Constructed from forged 4340 chromoly steel, each rocker arm is built for maximum strength and durability. They feature flame-hardened tips to withstand high-stress conditions and ensure longevity. The assembly also includes steel-backed bronze bushings for smooth operation. These premium materials make the SCat 20195 assembly suitable for both high-performance street builds and racing applications. This rocker arm assembly is designed for a universal fit on all standard VW Aircooled Type 1, 2, and 3 engines, including popular models like the Beetle, Karmann Ghia, Bus, and Dune Buggy. However, a critical installation note advises that switching to a 1.4 ratio will alter valve train geometry. An adjustable pushrod is required to determine the new pushrod length, ensuring proper rocker arm tip contact and travel across the valve stem. Additionally, users must check for coil bind with their valve springs due to the increased lift and ensure adequate clearance between the valve retainer and the top of the valve guide or seal. Standard clip-on valve covers may also interfere with these high-performance rocker assemblies, and bolt-on valve covers are recommended for better internal clearance and sealing.
