Designed by Precision Dynamics, manufactured in the United States.

The1-piece crank hub design eliminates the possibility of a crank hub from spinning. We designed our crank hub to have a keyway, with a higher shear strength over dowel pin designs.

The S55, whether stock or modified, has a possibility of crank hub failure. The OEM crank hub is a 3 piece design, utilizing friction disc to retain engine timing together. The friction disc depends on clamping force to clamp down the pieces of crank hub together. As the engine rotates counter clockwise, over time the crank bolt slowly backs out and loses its clamping force. This will cause engine timing to spin out of position. With enough load, engine timing can significantly be out of timing, causing the intake valves to hit against the engine piston. Severe failure such as this will require replacements of intakes valves, which will be an very expensive repair. We recommend to perform a crank hub service as preventative maintenance. While not all crank hubs fail, preventing it from failing will save you thousands of dollars and give a peace of mind.

Precision Dynamics Crank Hub for S55: Enhancing Reliability in High-Performance BMW Engines

Introduction

The S55 engine is a marvel of engineering, powering BMW’s M3 and M4 models with exhilarating performance and precision. However, like many high-performance engines, it has its quirks and potential weak points. One such concern has been the crank hub. In this blog post, we’ll delve into the Precision Dynamics Crank Hub for S55, exploring how it addresses a common vulnerability in these engines and enhances reliability.

Understanding the S55 Engine Crank Hub Issue

The S55 engine, found in the F80 M3, F82 M4, and other high-performance BMW models, has earned a reputation for its impressive power output and smooth delivery. However, it has faced an issue related to the crank hub. The crank hub is a component that connects the crankshaft to the camshaft and plays a crucial role in the engine’s timing. In some cases, the factory-fitted crank hub has been known to fail, leading to catastrophic engine damage.

The root cause of this problem lies in the design and materials of the OEM (Original Equipment Manufacturer) crank hub. It employs a pressed-on design that, under certain conditions, can become detached from the crankshaft, causing misalignment in the engine’s timing components. This can result in bent valves, damaged pistons, and costly repairs.

Precision Dynamics Crank Hub: A Solution

The Precision Dynamics Crank Hub for S55 engines offers a solution to this well-documented issue. Precision Dynamics, a reputable manufacturer specializing in performance parts for BMWs, developed an upgraded crank hub that addresses the shortcomings of the OEM design.

Key Features of the Precision Dynamics Crank Hub:

1. Solid Design: Unlike the pressed-on design of the factory crank hub, the Precision Dynamics Crank Hub is solid, eliminating the risk of separation.
2. Enhanced Materials: Precision Dynamics uses high-quality materials, including aerospace-grade steel, to ensure durability and longevity.
3. Improved Alignment: This upgraded crank hub features improved tolerances, ensuring precise alignment of the engine’s timing components.
4. Better Reliability: With its robust construction, the Precision Dynamics Crank Hub significantly reduces the risk of timing-related failures and associated engine damage.

Installing the Precision Dynamics Crank Hub typically involves professional installation by experienced mechanics or automotive technicians. Once installed, it offers several key benefits:

1. Enhanced Reliability: The upgraded crank hub provides peace of mind to S55 engine owners, reducing the risk of catastrophic engine failures associated with the OEM design.
2. Long-Term Durability: The use of high-quality materials and precision engineering means that the Precision Dynamics Crank Hub is built to last, even under demanding driving conditions.
3. Improved Performance: A reliable crank hub ensures that the engine’s timing remains precise, contributing to optimal performance and power delivery.
