Description

EC 1.1 Billet Aluminum Ratio Rockers for Non-Hemi Honda, Clone, Tillotson, and Predator Engines – Enhanced Performance & Durability


The EC 1.1 Billet Aluminum Ratio Rockers are expertly designed for Non-Hemi Honda, Clone, Tillotson, and Predator Cylinder Heads, offering superior performance and durability for both racing go-karts and mini bikes. These rockers are a perfect upgrade for those looking to enhance their engine's valve train stability without adding excessive weight.


Key Features and Benefits:

  • Needle Bearings for Reduced Friction:

The EC Rev Rockers are equipped with needle bearings, a customer-requested feature designed to reduce friction and wear. Without needle bearings, rockers are prone to seizing and damaging the rocker arm due to improper lubrication during assembly. By incorporating needle bearings, these rockers minimize the chances of failure, ensuring smoother operation at higher RPMs. However, it’s important to remember that proper lubrication is still essential. We recommend using Maxima Racing Oil Assembly Lube during installation to ensure optimal performance.

  • Lighter, Stronger Design:

These rocker arms are engineered with added material around the tip and rocker arm for increased strength, all while maintaining a lightweight design. The aim is to reduce weight, which helps stabilize the valve train at high RPMs and with aggressive camshaft profiles. Despite the added strength, we’ve managed to keep these rockers light enough for your performance needs.

  • Roller Tip for Reduced Wear:

The roller tip feature minimizes friction on the valve tips, reducing wear and extending the life of your valve train. While most applications do not require lash caps, these rockers feature a larger roller diameter for additional clearance and better performance in aggressive setups. If you're using Titanium valves, lash caps are recommended to prevent galling, but with stainless steel valves, the hardened tips of the valves will hold up without extra parts. This rocker setup is perfect for the market's growing demand for higher valve lift and aggressive performance setups.


  • Common Shaft Mounting for Stability:

The rockers are mounted on a common shaft or trunnion, which keeps them stable above the valve and pushrod, ensuring precise valve movement. The shaft mounting reduces distortion and deflection, allowing the valves to move more accurately according to the camshaft profile, which in turn improves overall engine performance.


  • 1.1:1 Ratio for Increased Valve Lift:

With a 1.1:1 ratio, these rockers provide a balanced increase in valve lift, improving the engine's acceleration and duration, particularly in high-performance setups with cams that lift the valves more than .150". While this ratio boosts performance, it may also require higher spring pressure to maintain control over the valves. Always check your cam specs to ensure you're running the proper seat pressure for your build.


Rev Rocker Features:

  • Aircraft-grade billet aluminum construction for strength and durability
  • Hardened roller tip with an oversized pressed-in axle and clip for extra strength
  • Larger diameter roller tip for additional clearance and improved performance
  • Titanium lash adjuster nuts for enhanced adjustment precision
  • Increased material on the rocker arm tip for added rigidity and strength
  • Needle bearings on the main shaft to reduce friction and improve durability
  • Brass washers protect the main shaft and rockers from damage

Why Choose EC 1.1 Billet Aluminum Ratio Rockers?

The EC 1.1 Billet Aluminum Ratio Rockers are the ideal choice for serious performance enthusiasts who demand precision and reliability in their small engines. With needle bearings, larger roller tips, and a 1.1:1 ratio, these rockers deliver improved valve train stability and increased power output. Plus, they offer a cost-effective solution with minimal price increase compared to other needle bearing rockers on the market.


Whether you're building a racing go-kart, a mini bike, or upgrading your Predator engine, the EC Rev Rockers provide the necessary performance to take your engine to the next level.

FAQ

Q1: What engines are compatible with EC 1.1 Billet Aluminum Ratio Rockers?
A1: The EC 1.1 Billet Aluminum Ratio Rockers are designed for Non-Hemi style engines, including Honda, Clone, Tillotson, and Predator cylinder heads. These rockers are a perfect fit for performance applications in go-karts, mini bikes, and small racing engines.


Q2: What is the benefit of using needle bearings in the rockers?
A2: Needle bearings significantly reduce friction and wear, improving the durability and longevity of the rocker arms. They also help prevent seizing and other issues caused by improper lubrication, ensuring smoother operation at high RPMs.


Q3: Do I need lash caps with these rockers?
A3: In most cases, lash caps are not required. They are typically used with Titanium valves to prevent galling. However, if you are using stainless steel valves, the hardened tips will hold up fine without lash caps. The roller tip design also helps with additional clearance for more aggressive setups.


Q4: What is the purpose of the larger roller tip?
A4: The larger roller tip improves clearance and performance by reducing friction on the valve tips. This feature also helps in applications where more valve lift and aggressive cam profiles are being used, ensuring smoother and more efficient valve operation.


Q5: Will these rockers work with my aggressive cam setup?
A5: Yes, the 1.1:1 ratio of the EC rockers increases valve lift, enhancing acceleration and duration. They are specifically designed to handle aggressive cam profiles and higher RPMs, making them ideal for high-performance setups. However, you may need to adjust spring pressure to accommodate the increased lift and valve acceleration.


Q6: Are these rockers compatible with aftermarket camshafts?
A6: Yes, the EC 1.1 Billet Aluminum Ratio Rockers are designed to work seamlessly with aftermarket camshafts, especially those that require increased valve lift. They help improve valve train stability and performance, making them perfect for high-performance camshaft profiles.
