DIRS-G Differential Brace for 2009-2014 V8 Chargers / Challengers / 300 RWD

Launched in 2019, Per4Mance Development reinvented the differential brace with a precision-engineered two-piece system that strengthens the rear differential while maintaining OEM ride comfort. The DIRS-G integrates seamlessly with factory IRS systems, improving traction, reducing wheel hop, and eliminating flex in high-horsepower setups.

Made from CNC-machined T-6061 billet aluminum, this brace is ideal for street, strip, and track applications ensuring the rear differential can handle the torque of 600–800 HP setups found in modern SRT and HEMI V8 models.
