These are FOA 3.0 triple rate coilovers with 18" 400-lb and 10" 300-lb springs and a 20-lb tender coil. 16" of travel. Unknown valving. They came off my full size Blazer and work fine, they need to be pressurized, though. No pits on the shaft or other damage which would impact performance, but I would rebuild them and the price reflects that. Springs were originally blue $200.
