Overview

The Per4mance DIRS differential brace is a two-piece reinforcement system designed to improve rear-end dynamics and reduce wheel hop for 2015-2023 V8 Chargers, Challengers, and 300 models with rear-wheel drive. This system integrates directly with the OEM differential to provide a third, triangulated mounting point for increased stability.

Show original supplier description

The Per4mance DIRS (Differential Integration and Reinforcement System) is a two-piece upgrade designed to strengthen the differential assembly on 2015-2023 V8 Dodge Chargers, Challengers, and Chrysler 300 RWD models. By creating a third triangulated integration point using an included OEM differential bushing, the system helps keep the rear suspension loaded and reduces wheel hop without increasing noise, vibration, or harshness (NVH). The brace is CNC-machined from T-6061 billet aluminum with a hard-anodized black finish. It features ARP fasteners, a galvanized bushing bolt, and tool-less PEM inserts for secure attachment to the rear cross-member. The design maintains convenient access to the differential's fill and drain plugs for routine maintenance. Important installation considerations include the handling of M10 inserts, which require careful alignment during setup. Please note that the installation of this brace may impact the manufacturer's warranty on the differential. The purchaser assumes all responsibility for the proper installation and use of this product.
