Differential Boost "DIRS" for Chrysler 300C, Dodge Challenger & Charger 5.7, 6.4 and Hellcat

Per4mance Development Differential Integration and Reinforcement System (DIRS) - strengthen your differential housing and improve both independent rear suspension function and traction on your Chrysler 300C, Dodge Challenger or Charger 5.7, 6.4 or Hellcat.

This system offers a significant improvement in the stability and durability of the differential, especially in high-performance vehicles.

By reinforcing and optimising the differential, DIRS helps to reduce wear and stress in intensive driving conditions. This ensures a longer service life for the components and increases the reliability of your vehicle, even under extreme conditions.

The DIRS system is manufactured from high quality, durable materials and is customised for a precise fit, ensuring easy installation and seamless integration into your vehicle. It is the ideal choice for enthusiasts looking to maximise the performance of their vehicle while improving the protection of critical drivetrain components.

Part 1 fastens the differential with the lower two main housing bolts and the three lower housing bolts to reinforce the differential.
Part 2 attaches to the rear crossmember and carries an OEM differential bushing (just like the two in the rear crossmember) to add a third integration point for attachment to the reinforced differential.
