Description
On the 2015–2023 Dodge Challenger/Charger (With Electronic Dampers SRT Hellcat), KW V4 is best approached as a chassis-tuning upgrade first and a ride-height change second.
KW V4 expands the tuning window with low-speed rebound plus separate low- and high-speed compression adjustment. That additional compression control is valuable when a build needs to distinguish slower platform motions such as pitch and roll from sharper wheel inputs over curbing, joints and bumps. The application-specific calibration is intended to give the chassis a more deliberate response than a one-size-fits-all suspension combination.
Why Choose the KW V4 for This Application?
Choose the V4 when the setup is developed enough that high-speed and low-speed damper events need to be treated differently. This is especially useful when ride quality over sharp impacts must coexist with stronger pitch and roll control.
Key Features
- Low-speed rebound adjustment

Enthusiast Setup Perspective
The tuning opportunity is greatest when the car has already moved beyond basic cosmetic modification. As grip and braking capability increase, damper control becomes progressively more important to keeping the chassis predictable. After installation, establish ride height and alignment first, then make damper changes in small increments and record them so the effect of each adjustment remains clear.
