4Runner 2025-2026 Toyota 4WD (w/0-1.75" rear lift) - Bilstein REAR 6100 Series Shock

Bilstein B8 6100 shock absorbers, part number 24-347440, are engineered specifically for the 6th Gen Toyota 4Runner models to deliver increased durability, improved control, and consistent performance in demanding conditions. Designed using over three decades of off-road racing and suspension development, the B8 6100 series is built for drivers who regularly encounter rugged roads, rough terrain, and harsh driving environments.

At the core of the B8 6100 shock is Bilstein’s monotube gas-pressure design, featuring a large 2.65-inch outer body and a 60mm digressive piston. This high-capacity design maximizes heat dissipation and minimizes oil foaming, ensuring the shock maintains consistent damping performance even during extended off-road use. The digressive piston technology provides firm control when needed while maintaining a smooth, composed ride during everyday driving.

Built for strength and longevity, the B8 6100 offers enhanced resistance to shock fade and wear, making it an ideal upgrade for 4Runner owners who demand reliability under load and during aggressive use. Whether navigating backcountry trails, washboard roads, or daily commuting, this direct-fit shock absorber delivers improved handling, stability, and ride quality without compromising comfort.
