The front KW V3’s have eye type mounts on both ends. These mounts have low compliance urethane bushings to transfer most forces through the damper itself. KW V3’s have the unique Phifer valve, which is a spring-loaded needle valve on the low-speed compression adjuster that gives another high-speed compression blow-off point. This helps the shocks be more sensitive to ripple type bumps. We are really looking forward to having double damping adjustability on our Corvette.
The KW HLS system is pretty simple. It consists of a hydraulic pump, two hydraulic cylinders that have spring seats on the top of them and the hydraulic line and fittings. The HLS system was originally designed for ride height control on DTM cars in order to semi-actively control the aero at high speeds. Later it was found that it made a cool and useful way to give a boost in ride height when needed for street driven cars!
The heart of the system is this lightweight compact hydraulic pump. The bracket that covers the pump is covered with a lot of holes which makes finding a mounting solution a breeze. A cool feature about the pump is that it’s totally self-contained, which conserves space and makes installation a snap. The KW hydraulic pump is smaller, lighter, quieter and faster than the typical compressor system that activates air cups.
These hydraulic cylinders slide over the shock bodies and fit underneath the springs. They are what actually lift the car when the system is activated. This is a nice sweet and compact solution. What is cool is that when activated the hydraulics don’t affect the spring rates, unlike air cups. So if you wanted to you could leave the car at the higher ride height while driving.
