Product Details

The KYB Gas-A-Just shock absorber increases vehicle stability, handling, and control through a monotube shock design. A monotube shock absorber is more responsive to the road and automatically adjusts to driving conditions. The Gas-A-Just shock will give a slightly firmer ride and provide additional control, limiting body roll and nose dive.
