Complete Valve Train Upgrade Kit– This combo includes everything needed for a professional-grade cylinder head performance build: 1.3 Ratio Aluminum Roller Rockers, a Stainless Steel Valve Kit with Bronze Guides (5.5mm stems, 27mm intake / 25mm exhaust), and 2 pieces of 4130 Chromoly Pushrods. Designed as a one-stop solution for enhancing your Predator 212cc Hemi engine.
High-RPM Stability & Power Gain– Engineered to perform reliably above 8,000 RPM. The 26lb performance springs and titanium retainers prevent valve float, while the 1.3 ratio roller rockers increase valve lift, allowing more air/fuel mixture into the cylinder. The result is a noticeable boost in horsepower and torque for racing or heavy-duty applications.
Precision Components for Optimal Geometry– The roller rockers are CNC-machined from high-strength aluminum alloy with a wear-resistant black anodized finish. The 0.187" diameter 4130 chromoly pushrods (5.135" length without ends) can be cut to length, enabling you to set perfect rocker arm angles after decking the head or using a small base circle cam.
Superior Durability with Premium Materials– Built to withstand extreme heat and stress. Stainless steel valves offer excellent corrosion and wear resistance, while bronze guides provide superior heat dissipation and reduced friction. This combination ensures smooth operation and extended engine life, even in boosted or high-compression setups.
Important Compatibility Notes– This kit is specifically designed for Predator 212cc Hemi engines. It also fits select Honda GX160/GX200 and clone engines, but note: non-Hemi heads require guide reaming to 5.5mm, and first-generation non-Hemi or 5mm stem valves are not compatible. Please verify your engine specifications before purchase.
