Review PROFORM Shaft Mounted Billet Roller Rockers Fits Buick fits 455

Introducing the Proform 66864 Shaft Billet Roller Rockers, specially designed for Buick 455 engines. These roller rockers are an essential upgrade for any performance enthusiast looking to enhance their engine's power output and efficiency.

Constructed from high-quality billet aluminum material, these roller rockers boast superior strength and durability compared to traditional cast rockers. The billet construction ensures a precise fit and finish, eliminating any potential issues with warping or distortion under high engine loads.

The Proform 66864 roller rockers feature full-length roller tips, which reduce friction and provide a smoother, more efficient operation. The rollers are precision-machined to ensure a perfect fit with the corresponding lifters, ensuring maximum contact area and minimal wear and tear.

These roller rockers also include self-lubricating, PTFE-coated tips. PTFE, or polytetrafluoroethylene, is a high-performance, non-stick material commonly used in engine components due to its exceptional lubricity and wear resistance. The self-lubricating tips reduce the need for frequent oil changes and ensure that the roller rockers operate smoothly and quietly, even under high RPMs.

The Proform 66864 roller rockers are designed to provide improved valve control and stability, resulting in increased power and torque output. They are an excellent choice for high-performance applications, such as racing or high-horsepower builds.

Installation of these roller rockers is straightforward and can be completed using standard hand tools. The roller rockers come with all necessary hardware, including new pushrods and retainers, making this an all-inclusive kit for your engine upgrade.

In summary, the Proform 66864 Shaft Billet Roller Rockers are a high-performance upgrade for any Buick 455 engine. Their billet construction, full-length roller tips, and self-lubricating PTFE-coated tips offer superior strength, durability, and efficiency, making them an excellent choice for enthusiasts looking to maximize their engine's potential.
