Roller rockers are an essential component of any high-performance engine. These mechanical devices are designed to reduce friction between the valve stem and the camshaft, resulting in improved valve control and increased horsepower. They feature a roller bearing that rolls along the surface of the camshaft, reducing the amount of friction and wear on the valve train. Roller rockers are available in a variety of materials, including aluminum and steel, and come in a range of ratios to suit different engine configurations. They are an excellent upgrade for any engine builder looking to improve the performance and reliability of their engine.

Frequently Asked Questions (FAQs)
1. What is the purpose of a roller rocker?
The purpose of a roller rocker is to reduce friction and wear in the valve train of an engine. It uses needle bearings or a single bearing ball at the contact point between the rocker and the valve, minimizing metal-on-metal contact and reducing friction. This helps prevent uneven wear and damage to the valve guide.
2. Do roller rockers add horsepower?
Roller rockers do not directly add horsepower. While they use bearings instead of bushings, which reduces friction, the power gains are not significant. The benefits of roller rockers lie in their improved durability, accuracy of the rocker ratio, and reduced wear and tear on the valve train.
3. Are full roller rockers worth it?
Full roller rockers can be worth it for certain applications. Besides potential power benefits from an increased rocker ratio, they offer advantages such as more accurate advertised ratios compared to stock rockers, reduced friction, and improved durability. However, their worthiness depends on the specific needs and goals of the engine.
4. What is the difference between roller rocker and standard rocker?
Roller rockers are significantly different from standard rockers. They incorporate friction-reducing components, stiffening components, and weight/inertia reduction aspects. These design features help reduce wear, improve performance, and enhance the overall durability and efficiency of the valve train.
5. Do you need a different cam for roller rockers?
No, a different cam is not necessarily needed for roller rockers. Roller camshafts and lifters can be used with non-roller rockers, and roller rocker arms can be used with flat-tappet solid or hydraulic camshafts. They are not dependent on each other and can be mixed and matched as needed.
6. What is a benefit to a roller lifter?
A roller lifter has a wheel on the bottom that rides on the camshaft, reducing friction and wear. This allows for the use of more aggressive camshaft profiles and improves overall engine performance. Roller lifters help minimize wear and damage to the valve train components.
7. What is the advantage of roller rocker arms?
Roller rocker arms offer several advantages. Firstly, they contribute to a quieter engine operation. Secondly, the use of bearings reduces friction, preventing wear and damage over time. Lastly, roller rockers can enhance an engine's overall performance by reducing friction and improving the efficiency of the valve train.
8. How much more lift does 1.6 rockers add?
With 1.6 rockers, the lift of the valve increases by approximately 0.031 inch. This means that a 1.6:1 rocker ratio will provide a slight increase in valve lift compared to the stock ratio, which can potentially improve engine performance.
9. How long will roller rockers last?
The lifespan of roller rockers depends on various factors, such as the engine's usage and maintenance. With regular oil changes and a stock valvetrain, roller rockers can last around 20,000-30,000 miles on a daily driven engine. However, in engines with high mileage or more aggressive setups, the lifespan may be shorter, requiring more frequent replacements.
