Ripp Crank Pin Kit

5.7L / 6.1L / 6.4L Dodge HEMI V8 Engines

RSH5764PIN

Overview:

The Ripp Crank Pin Kit is engineered specifically for Dodge HEMI V8 engines, including the 5.7L, 6.1L, and 6.4L variants. This kit provides a reliable solution to secure the crankshaft to the harmonic balancer, ensuring stability and preventing slippage under high-performance conditions. Whether your vehicle is naturally aspirated or equipped with a supercharger, the crank pin kit helps maintain the harmonic balancer’s position, which is critical when running elevated horsepower levels or forced induction setups.

Designed for enthusiasts and professional builders alike, this kit is an essential upgrade for anyone looking to enhance engine durability and reliability during demanding driving or racing scenarios.

Key Features:

The Ripp Crank Pin Kit includes precision-engineered components that simplify installation and guarantee a secure fitment. Key features include:

• High-speed steel drill bit for accurate and clean drilling
• Tool steel dowel pin engineered for maximum strength and wear resistance
• Drill guide/template to ensure precise alignment and depth control
• Crank bolt designed specifically for use with the drill template
• Compatible with 5.7L, 6.1L, and 6.4L Dodge HEMI V8 engines
• Prevents harmonic balancer from spinning or loosening under high torque
• Works effectively on both supercharged and naturally aspirated engines

Construction & Design:

The kit’s components are crafted from premium materials to withstand the stresses of high-performance engine operation. The dowel pin is made from hardened tool steel, providing exceptional durability and resistance to shear forces. The included drill bit is manufactured from high-speed steel, ensuring sharpness and precision for clean drilling into the crankshaft. The drill guide and crank bolt are designed to maintain perfect alignment during installation, minimizing the risk of errors and ensuring a flush, secure fitment.

Installation & Fitment:

Installation requires careful drilling into the crankshaft to insert the dowel pin, which locks the harmonic balancer in place. It is recommended to mark the drill bit with blue painter’s tape to control drilling depth and avoid over-penetration. Regularly check progress during drilling to ensure the dowel pin sits flush with the crank pulley surface. The harmonic balancer bolt should be torqued to 130 ft-lbs to secure the assembly properly. This kit is included with Ripp Supercharger systems for all compatible V8 engines, but it can also be installed independently on both supercharged and non-supercharged vehicles.

What's Included:

• High-speed steel drill bit
• Tool steel dowel pin
• Drill guide/template
• Crank bolt for drill template

Ideal For:

This crank pin kit is ideal for Dodge HEMI V8 owners who are upgrading their engines for increased power output or forced induction. It is especially beneficial for those running superchargers or other high-horsepower modifications where harmonic balancer slippage can cause engine damage or performance issues. Whether you are a professional tuner, racer, or enthusiast seeking enhanced engine reliability, this kit provides a straightforward and effective solution.
