Bilstein B8 8112 Series 03-09 Toyota 4Runner Zone Control Monotube Front Left Corner Module

This is the Bilstein B8 8112 Series Zone Control Monotube Front Left Corner Module, designed specifically for your 2003-2009 Lexus GX470, Toyota 4Runner, or FJ Cruiser. This isn't just a shock absorber; it's a position-sensitive coilover system that changes how your vehicle handles everything from daily driving to rough terrain.

What makes this module special is its ZoneControl CR technology. It uses a triple piston design with three stages of compression valving and two stages of rebound valving. This means it can provide a comfortable ride during normal driving, absorbing small bumps smoothly, but then stiffen up effectively to control larger impacts, like hitting a pothole or going over off-road obstacles. The coilover itself is a 2.65-inch body monotube unit with a threaded spring seat, allowing you to adjust the ride height from 0 to 3.8 inches, depending on your specific application. It also comes with a 60mm remote reservoir, which holds more oil and helps keep the shock cooler during extended use, especially important when you're pushing your vehicle hard.

Installation is made easier because this is a direct fit coilover module, and it includes a bolt-on anodized reservoir chassis mount. You'll get a well-built suspension component that offers a notable improvement in both everyday comfort and off-road capability.
