Differential Brace “DIRS-G” for Chrysler 300C, Dodge Challenger & Charger 5.7, 6.1 and 6.4 from 2009 to 2014

The DIRS-G (Differential Integration and Reinforcement System) from Per4Mance Development is a high-quality, two-part differential reinforcement and integration system that was specially developed for Dodge Charger, Challenger and Chrysler 300 with V8 engine and rear-wheel drive from model years 2009 to 2014.
It is a completely redesigned solution that has been developed with the clear aim of achieving the best possible result for the standard IRS (Independent Rear Suspension) system.

Per4Mance Development wanted to counteract the enormous stress to which the differential is exposed in vehicles with increased engine power. The development team asked itself two key questions:

• Can a technically superior solution be developed?
• Can this new solution work more harmoniously with the standard IRS?

The result is the DIRS-G - a two-part system that builds on the success of the tried-and-tested DIRS for vehicles built from 2015 onwards and consistently develops it further.

The system consists of two components that together ensure optimum power transmission and stabilization of the differential housing:

• Part 1 is attached directly to the differential housing via three housing bolts and thus provides structural support for the differential.
• Part 2 is attached to the rear subframe (rear cross-member) and carries an original OEM differential bushing - just like the two factory bushings in the rear subframe. This creates a third, triangulated integration point that additionally „anchors” the reinforced differential and optimally distributes the forces.

Technical features

• Made in the USA - CNC-milled billet aluminum of alloy T-6061 for maximum strength with minimum weight
• OEM differential bushing - ensures tool-like, low-vibration integration into the chassis
• ARP fastening screws and US-made galvanized socket screws for maximum durability and corrosion protection
• P4D tool-free insert for attachment to the subframe - simplifies assembly considerably
• Hard anodized surface in black - scratch and corrosion resistant, durable look
• Free access to the filler and drain plugs of the differential is fully maintained

Advantages & user reports

• Excellent processing quality and professional packaging
• Noticeably increased stability and robustness of the entire differential range
• Improved driving dynamics at the rear - more traction, less wheel hop under full load acceleration
• No increase in NVH (noise, vibration, harshness) - ride comfort is fully maintained

Compatibility

The DIRS-G is only suitable for vehicles equipped with the Getrag 226 differential. This
Differential can be recognized by the characteristic cooling fins on the housing, as can also be seen in the product photos.
Vehicles with a smooth differential housing without cooling fins are not compatible - please check before purchasing.
