Engine Works OE Style Rocker Arms

Engine Works OE-style rocker arms are drop-in replacement valvetrain components designed to match the factory specifications, geometry, and performance of original equipment stock engines. Order the set of 16 recommended for your application.

* Key features and design:
-- Factory geometry: These arms maintain the exact stock rocker ratio (such as 1.7 for GM LS engines) to ensure proper valve lift and pushrod alignment without needing custom modifications
-- Upgraded materials: While they look and function like stock parts, aftermarket versions (like Engine Works' LS series) often feature upgraded materials, such as heavy-duty steel trunnions or improved captive roller bearings, to enhance durability over fragile factory components
-- Direct fit: They serve as 100 percent bolt-on, drop-in replacements, meaning they reuse or match standard mounting hardware without requiring guide plates or specialized valve covers

* Common applications:
-- GM LS engines: Widely produced for applications like GM LS1, LS2, LS6, and LS3/L99 engines to replace worn-out factory units during a rebuild or refresh
-- Stock and mild rebuilds: Ideal for daily drivers, restorations, or mild street performance builds where extreme high-lift aftermarket camshafts and aggressive roller rockers are unnecessary
