Product Details

The Bilstein B8 6112 series is engineered around a snap-ring grooved coilover body that allows multiple spring seat positions for front lift tuning. Part number 47-310025 uses a 600 lb/in front main spring rate and a 4.79-inch stroke to balance ride control with suspension travel. For Toyota 4Runner, Lexus GX460, and Toyota FJ Cruiser owners, this setup is a practical way to gain clearance for larger tires while maintaining controlled on-road and off-road damping. This part number 47-310025 is part of the Bilstein B8 6112 line, which focuses on direct-fit front suspension performance for Toyota 4Runner, Lexus GX460, and Toyota FJ Cruiser platforms.

This part cross-references Bilstein 46-227294 for the same application.

What It Helps Address

• Front-end sag from factory suspension wear or added vehicle load
• Limited clearance for larger tires on Toyota 4Runner, Lexus GX460, and Toyota FJ Cruiser platforms
• Reduced front wheel travel during off-road use
• Uncontrolled ride motion from stock suspension tuning
• Need for a direct-fit front leveling solution with adjustable lift height

Installation Notes

Install on the front axle only. Lift height varies by vehicle application and snap-ring groove position, so final ride height should be set during assembly. Verify KDSS configuration on 2020-2022 and 2010-2016 Toyota 4Runner applications before installation, since lift range differs with and without KDSS. Professional installation and post-install alignment are recommended after suspension changes.

Quality Assurance

Bilstein B8 6112 suspension components use a monotube damper design and application-specific spring matching to support consistent damping control. The zinc-plated damper finish and billet aluminum spring seats reflect the kit’s heavy-duty construction for street and trail use.
