The EC 1.2 Billet Aluminum Ratio Rockers are expertly designed to optimize performance for Non-Hemi style Honda, Clone, Tillotson, and Predator cylinder heads. Perfect for high-performance applications such as go-karts, mini bikes, and small racing engines, these rockers provide a significant boost to valve train stability and engine efficiency.

Needle Bearings for Improved Performance

The EC 1.2 Billet Ratio Rockers feature needle bearings that drastically reduce friction and wear, especially at higher RPMs. Unlike traditional bearing-less rockers, which require assembly lubrication to prevent seizing, the inclusion of needle bearings ensures smoother operation and enhanced durability. Proper lubrication is still essential, so be sure to use high-quality assembly lube, like Maxima Racing Oil, to protect your engine components during installation.

Larger Roller Tip for Enhanced Valve Movement

To meet the demands of high-lift and aggressive cam setups, the EC 1.2 Billet Rockers incorporate a larger roller tip. This design reduces friction on the valve tips and provides additional clearance for valve retainers. While lash caps are not typically required for stainless steel valves, the larger roller tip ensures compatibility with more aggressive valve configurations, making these rockers ideal for high-lift cam setups in competitive environments.

High-Strength Design with Minimal Weight

Although the 1.2 Billet Ratio Rockers are beefier to accommodate the larger roller tips and needle bearings, the design has been optimized to keep the weight as low as possible. By maintaining a lightweight valve train, the rockers help stabilize valve movement, which is especially important for engines running at high RPMs and those with aggressive camshafts. This improves engine response and overall performance during races or competitions.

Precision and Durability

These rockers are CNC-machined from aircraft-grade billet aluminum, ensuring precise construction and superior strength. The roller tips are equipped with an oversized pressed-in axle with a clip, further increasing durability. The needle bearings in the main shaft provide better performance by reducing wear and tear, allowing your engine to perform at its peak for longer periods.

Optimized for 1.2:1 Ratio Performance

With a 1.2:1 ratio, these rockers increase valve lift, acceleration, and duration, particularly beneficial for camshafts with profiles that require higher lift. By improving valve movement, the rockers contribute to overall engine performance, but spring pressure may need to be increased to match the demands of higher lift and acceleration. Check your camshaft's specifications to ensure optimal spring pressure for your application.

FAQ

FAQ for EC 1.2 Billet Aluminum Ratio Rockers

Q1: What engines are compatible with the EC 1.2 Billet Aluminum Ratio Rockers?

The EC 1.2 Billet Aluminum Ratio Rockers are compatible with Non-Hemi Honda, Clone, Tillotson, and Predator engine heads. These rockers are ideal for high-performance applications like go-karts, mini bikes, and other small engines.

Q2: What makes the EC 1.2 Billet Aluminum Ratio Rockers unique?

The EC 1.2 Billet Aluminum Ratio Rockers are designed with needle bearings to reduce friction and wear, which increases durability and performance. The larger roller tips improve valve tip contact, offering more clearance and reducing friction. These rockers are CNC-machined from aircraft-grade billet aluminum for strength, precision, and long-lasting durability.

Q3: What is the benefit of the 1.2:1 ratio in these rockers?

The 1.2:1 ratio increases valve lift, acceleration, and duration for improved engine performance. This ratio is particularly useful for high-performance applications, where aggressive cam profiles and high RPMs are common. It results in better valve movement and efficiency, especially with larger valve setups.

Q4: Do I need to use any special lubrication when installing these rockers?

Yes! Proper lubrication is essential for the longevity and performance of your valve train. While the needle bearings help reduce friction, we recommend using Maxima Racing Oil Assembly Lube when installing the EC 1.2 Billet Aluminum Ratio Rockers to ensure smooth operation and prevent seizing or damage.

Q5: Will I need to increase spring pressure when using these rockers?

Yes, if you're using a high-lift camshaft or running at higher RPMs, you may need to adjust your spring pressure. Increasing the valve lift and acceleration can put additional strain on the valve train, so it's essential to use stronger valve springs to match the performance improvements. Check your camshaft’s specifications for recommended spring pressure.

Q6: How do I know if these rockers are right for my engine setup?

To determine if the EC 1.2 Billet Aluminum Ratio Rockers are the right fit, you should consider your engine's specific requirements, including the camshaft profile, valve setup, and RPM range. These rockers are ideal for high-performance engines with welded cam profiles and those operating at higher RPMs. If in doubt, consult with a professional mechanic or check your engine's specifications.

Q7: Are these rockers available for other engine types?

Currently, the EC 1.2 Billet Aluminum Ratio Rockers are designed specifically for Non-Hemi Honda, Clone, Tillotson, and Predator engines. If you have another engine type in mind, please check our product listings or contact our customer support team for compatibility information.
