Product Details
This is the KYB Gas-A-Just rear shock absorber for your 2003-2009 Toyota 4Runner, excluding models with the X-Reas system or adjustable suspension. If your 4Runner's rear end feels a bit soft or bouncy, especially when carrying loads or going over bumps, this shock can help restore a more controlled and comfortable ride. It's designed to replace your original shock and bring back that factory feel.
KYB's Gas-A-Just shocks use a nitrogen gas pressure charge to help prevent fluid aeration, which is what causes that spongy feeling in worn-out shocks. This means you get a more consistent performance, even under tougher conditions. The valving inside is tuned to offer a good balance between ride comfort and handling stability, making it a solid option for daily driving and occasional hauling.
When you're replacing your rear shocks, it's a good idea to check the condition of your rear springs and any mounting hardware. If you're doing one side, it's always best practice to replace the shock on the other side at the same time to ensure even handling and wear.
