Per4mance Development LLC Launches Patented DIRS-R Differential Brace and Ultimate Reinforcement Package for High-Performance Dodge & Chrysler V8 Models
Thursday, October 9, 2025
HARRISBURG, Pa., Oct. 1, 2025 /PRNewswire/ -- GetPer4mance.com, the official home of Per4mance Development LLC, has expanded its patented Differential Integration and Reinforcement System (DIRS) product line with the release of the lighter, stronger DIRS-R Differential Brace and the new Ultimate Package Kit, designed specifically for 2015-2023 Dodge Charger, Challenger, Demon 170, and Chrysler 300 V8 performance sedans.
DIRS (R Version): Lighter, Stronger, Smarter
The DIRS-R is the next evolution of the original DIRS, now available for all 2015-2023 V8 Dodge Chargers, Challengers, Chrysler 300 RWD models, and the Dodge Demon 170.
Key improvements include:
-- 32.5% lighter than the original DIRS (5.9 lbs. total weight)
-- American-made, CNC-machined T-6061 billet aluminum
-- OEM differential bushing and Grade 10 stainless steel hardware
-- Hard-anodized black coating for durability
-- EZ access to fill and drain plugs -- no brace removal required
-- Works with stock and most aftermarket exhaust systems, including Borla
The two-piece design reinforces the differential case and adds a triangulated integration point to the rear cross-member, significantly reducing case flex and improving traction. Customers consistently report improved rear-end stability, reduced wheel hop, with no significant increase in NVH.
Ultimate Package: Complete Drivetrain Reinforcement
For drivers who want maximum reinforcement, the new Ultimate Package Kit combines three proven upgrades in one solution:
1. DIRS-R Differential Brace
2. Per4mance Development Billet Race Brace (BRB)
3. JXB Performance Driveshaft Center Support Bearing Upgrade (includes both
Street and Track bushings)
Together, these components address differential case flex and excessive movement and driveshaft support, giving owners unmatched confidence in both street and track conditions.
Commitment to Quality
"Our DIRS line was created to solve real-world performance challenges faced by Mopar owners," said Rob Gundermann, a spokesperson for Per4mance Development. "The updated DIRS-R and the Ultimate Package give enthusiasts the freedom to push their vehicles harder without sacrificing reliability or comfort."
Customer Praise
Early adopters are already sharing their feedback. Matthew A. of Georgia recently wrote:
"Unbreakable Grip! All the bounce and unintentional tire slip and wheel hop under hard launch conditions is GONE. No more anxiety about busting my differential either..."
