What is the benefit of a monotube shock absorber design?

A monotube design separates the shock's oil and gas into different chambers. This helps prevent the oil from foaming under heavy use, which can lead to inconsistent damping. It generally offers more stable and controlled damping performance.

Does this shock absorber come with any mounting hardware?

This product is a direct replacement shock absorber and is designed to use the original mounting hardware from your vehicle. Please refer to the manufacturer's installation instructions for any specific details.

How often should I replace my rear shock absorbers?

Shock absorbers typically wear out over time, usually between 50,000 and 100,000 miles, depending on driving conditions. Signs of wear include a bouncy ride, poor handling, or visible leaks from the shock body.

Product Details

Built with a monotube design, this KYB rear shock absorber uses a gas-charged, high-pressure system to keep the fluid from foaming. This helps maintain consistent damping performance, even when the suspension is working hard on rough roads or during towing. It’s a direct replacement for your 2010-2024 Toyota 4Runner, 2010-2014 Toyota FJ Cruiser (RWD models), and 2010-2014 Lexus GX460 Base models.

The monotube construction separates the gas and oil, which helps prevent cavitation and ensures the shock works effectively. This means you get a more stable and controlled ride compared to a twin-tube design, especially under demanding conditions. KYB has been making suspension components for a long time, and this shock is built to meet the original equipment specifications for your vehicle, helping to bring back that factory feel to your ride.

Replacing your rear shocks is a common maintenance item that can make a big difference in how your vehicle handles bumps and keeps its tires in contact with the road. This shock is designed to fit right without any modifications, making it a straightforward replacement for your worn-out original part.
