Upgrade your valve train with a complete Rocker Arm Guardian Kit built for high‑lift cams and long service life. 🔧

This kit replaces worn OEM components with performance hardware engineered for precision and durability, including forged roller rockers, hardened shafts, studs and a heat‑treated head bolt set.

• Forged roller rocker arms with 1.640 ratio; rollers eliminate valve thrust for reduced valve‑train wear.

• Hardened and surface‑ground shafts, formed threads and reusable 12‑point head bolts for reliable clamping.

Designed for cams with .550 in or greater, compatible with stock or CNC heads, and serviceable for generations. 🔩

Kit includes:
• 4x rocker arm shafts
• 8x rocker arm studs
• 8x head bolts
• 4x forged roller rocker arms
