Description
On the 2015–2020 Mercedes-Benz GLA 45 AMG (X156), KW V3 is best approached as a chassis-tuning upgrade first and a ride-height change second.
KW V3 is built around independent low-speed rebound and compression adjustment. KW's current V3 architecture provides 16 rebound clicks and 12 compression clicks, giving an enthusiast meaningful control over chassis support, response and ride without moving into a dedicated motorsport damper. 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 V3 for This Application?
Choose the V3 when the car needs a broader operating window. Independent rebound and compression control makes it easier to balance ride, platform support and tire contact as the build moves between street use and more demanding driving.

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.
Important KW Fitment Notes
- KW Note 2: Height adjustable front and rear axles (front axle threaded strut housings, rear axle adjustable springs + dampers)
- KW Note 67: Valving is adjusted by adjustment knobs, rebound is only adjustable if the top of the piston rod is accessible. This will depend on the design of the vehicle.
Fitment note: Specifications above are tied to the exact KW part number shown and the application data in the supplied KW jobber sheet. Confirm the vehicle's drivetrain, factory electronic suspension, axle weight and any listed hardware requirements before ordering.
