Does this shock absorber come with new mounting hardware?

This KYB Gas-A-Just shock absorber is sold individually and typically does not include new mounting hardware. It's recommended to inspect your vehicle's existing hardware for wear and tear and replace any worn components as needed.

Should I replace both rear shocks at the same time?

Yes, it is strongly recommended to replace rear shock absorbers in pairs. Replacing both shocks at the same time ensures balanced handling and prevents uneven tire wear and suspension performance.

What does 'Gas-A-Just' mean for my ride?

The 'Gas-A-Just' technology uses nitrogen gas pressure to help keep the shock's fluid from foaming up, especially during hard use. This helps maintain consistent damping performance and prevents that 'spongy' feeling you might get from worn-out shocks.

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.
