Bilstein B8 8112 ZoneControl CR Front Right Coilover for 2010–2024 Toyota 4Runner

The Bilstein B8 8112 Series Front Right Shock Absorber & Coil Spring Assembly is engineered for 2010–2024 Toyota 4Runner owners who want more than a basic lift. This right-hand front coilover replaces the stock strut with a position-sensitive, remote-reservoir system that delivers a smoother ride on pavement and confident control on rough trails. It’s built specifically around the 5th gen 4Runner chassis, so you gain usable wheel travel, better composure at speed, and the ability to dial in front ride height without piecing together a mix of parts.

At the core of this B8 8112 is Bilstein’s ZoneControl CR technology: a triple-piston, position-sensitive design with three compression zones and two rebound zones. Instead of one generic damping curve, the shock changes its behavior through the stroke. Light, everyday inputs are handled by the main 60 mm digressive piston for a calm, comfortable ride. As the suspension compresses deeper over whoops, washboards, or unexpected hits, secondary compression and rebound zones progressively increase control to resist bottoming, nose-diving, and harsh top-out events. This architecture often eliminates the need for separate bump stops or limit straps, simplifying your front suspension while adding control typically found in race-level setups.

To keep performance consistent on long trail days and hot highway miles, the 8112 uses a large 60 mm monotube body paired with a remote reservoir. The reservoir increases oil capacity and improves cooling, which helps maintain damping feel when lesser shocks start to fade. The coilover comes as a complete, pre-assembled module with a threaded spring seat that provides an adjustable front lift range (commonly about 1.5"–3.5" on 4Runner applications, depending on setup). That adjustability lets you:

• Level out factory rake for a more aggressive stance
• Clear larger front tires and improve approach angle
• Compensate for added weight from armor, skid plates, or a winch bumper

Construction details are aimed squarely at demanding 4Runner owners. The coilover uses a steel monotube body with an EVO grey finish and black coil spring, plus aluminum and zinc-plated components that stand up to mud, road salt, and desert dust. A gas-charged internal design keeps response crisp, while the precision valving and vehicle-specific spring pairing are tuned around the weight and geometry of the 2010–2024 4Runner platform. Hardware and mounts are designed to integrate with factory mounting points on the front right corner, making this a direct bolt-in replacement rather than a universal compromise.

Because this is an individual front right assembly, it’s ideal if you’re replacing a damaged or worn coilover on an existing Bilstein B8 8112 setup, or building your suspension corner by corner. When paired with the matching driver-side 8112 and properly tuned rear shocks and springs, you can expect tighter steering response, reduced brake dive, improved mid-corner stability, and far better control when the trail gets choppy. Daily driving remains composed and predictable, while off-road performance jumps into a completely different league compared to factory struts or basic lift spacers.

Who is this 4Runner front right 8112 coilover for? It’s targeted at 5th gen Toyota 4Runner owners who:

• Use their vehicle both as a daily driver and as a serious trail or overland rig
• Want adjustable front lift without sacrificing ride quality
• Need more control and bottom-out resistance than traditional “lift kit” shocks provide
• Prefer a complete, tuned coilover assembly from a suspension-focused brand rather than a generic solution

Backed by Bilstein’s long history in off-road and OEM suspension, the B8 8112 Series Front Right Shock Absorber & Coil Spring Assembly (SKU: BIL41-326251) brings advanced damping technology, rebuildable-grade construction, and true on-/off-road versatility to your 2010–2024 Toyota 4Runner. If you’re ready to move beyond entry-level lifts and invest in a front suspension that actually matches how you drive, this right-side 8112 is the cornerstone of a serious 4Runner setup.
