What is multimatic DSSV?

The Multimatic DSSV Multimatic first designed the Dynamic Suspensions Spool Valve (DSSV) damper technology for racing applications in the early 2000s. … Spool valves have been used for fluid control in hydraulic systems for decades but never before in a suspension damper.

What are spool valve dampers?

Spool valves (001) dynamically vary damping force by controlling fluid flow through precisely shaped ports using a spring-loaded shuttle. Each DSSV damper contains two spool valves, one for compression and one for rebound. Windows: There are six ports, or windows (002), on each street-car valve.

What shocks does the Colorado ZR2 have?

ZR2 Front Long Travel DSSV Shocks The Chevrolet Performance ZR2 Front Long Travel Dynamic Suspension Spool Valve (DSSV) Shocks are designed and tuned specifically for off-road racing by Chevrolet Performance and Multimatic. They provide up to a 15% increase in overall suspension travel on 2017+ Colorado ZR2 models.

What is suspension damper?

Suspension damping is the process of controlling or stopping the spring’s oscillation, either when it compresses or rebounds (usually both). This typically works by introducing a hydraulic cartridge into the mix, with a fluid and some controlled valving.

What does ZR2 mean on a Chevy Colorado?

Regular Production Option ZR2 is a special off-road/suspension package offered by General Motors on their mid-size pickup trucks and SUVs. … The ZR2 package was gradually phased out with the S-Series pickup and SUV lines. However, it has made a comeback as an option on the 2017 Chevrolet Colorado.

Is a damper the same as a shock?

The proper name for shock absorbers is “damper” as it serves to dampen motion. While shock is absorbed by the spring, the damper functions to modulate the oscillations (bouncing).

How does a spool work?

A full spool replaces the carrier, spider, and sides gears. … The spool’s ring flange bolts onto the ring gear. So, the ring and pinion do their job, redirecting torque 90 degrees from the driveshaft to the wheels but the housing has lost its ability to differentiate wheel speeds between the wheels.

What is the difference between absorber and damper?

A shock absorber is a mechanical or hydraulic device designed to absorb and damp shock impulses. Damper is a shock absorber that is used in independent suspension system to absorb the vibrational energy by resisting motion via viscous friction.
