Part #: CFR-7750-M-ADP-KIT

Overview

The CFR Performance Aluminum Hellcat Supercharger Adapter Plates are precision-engineered components designed to facilitate the installation of Hellcat superchargers on early Gen 3 Mopar HEMI engines. Specifically crafted for 5.7L Non-VVT engines from 2005 to 2008 and 6.1L SRT8 engines from 2005 to 2010, these adapter plates provide a seamless and reliable interface between the Hellcat supercharger and original HEMI cylinder heads.

Construction & Design

Manufactured from billet CNC-machined aluminum, these adapter plates combine precision engineering with durable materials to withstand the rigors of forced induction. The CNC machining process ensures exact tolerances for a perfect fit between the Hellcat supercharger and early Gen 3 HEMI cylinder heads.

The aluminum material offers an excellent strength-to-weight ratio, reducing added mass while maintaining rigidity under boost pressures. The machined aluminum finish enhances corrosion resistance and provides a sleek, professional look that complements high-performance engine builds. Every detail is engineered to maintain factory bolt patterns and alignment, preventing stress on mounting points and ensuring consistent performance over time.

Installation & Fitment

Installation of the CFR Performance adapter plates is straightforward for experienced mechanics and enthusiasts familiar with HEMI engine modifications. The kit includes all necessary bolts and steel lock washers to secure the plates firmly in place.

These plates are designed specifically for 2005–2008 5.7L Non-VVT and 2005–2010 6.1L SRT8 HEMI engines found in Chrysler 300, Dodge Challenger, Charger, Durango, Magnum, and Jeep Grand Cherokee models. While the plates fit 2009–2010 5.7L and 6.4L HEMI engines, additional upgrades to the alternator, A/C compressor, harmonic balancer, power steering pump, and water pump (2011+ versions) are required due to spacing differences. Note that these adapter plates are not compatible with Dodge Ram trucks.
