Product Details

If your 2019-2021 Chevrolet Silverado 1500 or GMC Sierra 1500 with the Z85 increased capacity suspension feels a bit worn out in the rear, replacing the shocks is a smart move. These KYB Gas-a-Just shocks are built to bring back that comfortable ride and stable handling you expect from your truck.

KYB designs these shocks with a monotube construction, which helps them manage heat better than twin-tube designs, especially under load. This means more consistent performance whether you're just cruising around town or hauling a load. They use a nitrogen gas charge to help prevent the fluid from foaming, which also contributes to a smoother, more controlled ride. They fit right into your truck's factory mounting points, making installation straightforward.

This rear shock is specifically made for trucks equipped with the Z85 suspension package, which typically means it has increased capacity. If you're looking to replace worn-out rear shocks and want a reliable, well-built option, these KYB Gas-a-Just shocks are a solid choice.
