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.
