Overview

The Per4Mance DIRS-F is a front differential brace designed to reinforce and stabilize the front differential case on high-performance Jeep and Dodge vehicles. This system uses a triangulated integration design to support the differential housing and reduce the risk of case damage. The kit features CNC-machined T-6061 billet aluminum construction with a hard-anodized black finish and includes Grade 10.9 hardware.
Show original supplier description
The Per4Mance DIRS-F is a specialized Differential Integration and Reinforcement System engineered to bolster the front differential case on high-horsepower modified Jeep and Dodge platforms. By utilizing a two-part support structure, the system anchors to the vehicle frame and the differential housing, incorporating an OEM differential bushing to create a third, triangulated integration point. This stabilizes the differential and reduces stress on the passenger side output shaft extension, which is susceptible to failure under heavy load. Constructed from American-made, CNC-machined T-6061 billet aluminum, this brace provides robust reinforcement without increasing noise, vibration, or harshness (NVH). The kit is finished in a hard-anodized black coating and includes all necessary Grade 10.9 installation hardware, including Loctite. Note that due to the welded extension design on the rear frame mount, slight inconsistencies in the anodized finish may be present in that area. This brace is compatible with 2015+ Jeep Grand Cherokee SRT 392 and Trackhawk models, as well as 2015+ Dodge Durango SRT 392 and Hellcat vehicles. Please be aware that the use of this component may impact the manufacturer's differential warranty, and the purchaser assumes full responsibility for installation and operation.
