Bilstein B6 4600 Rear Shock for 2nd-Gen 4Runner (1990–1995)

The Bilstein B6 4600 Rear Shock is engineered to refine rear suspension performance on stock-height 2nd-Gen 4Runner platforms. It improves damping consistency, ride comfort, and load stability while preserving factory suspension characteristics and geometry.

The digressive piston adjusts damping force in response to changing road conditions, delivering firm control under heavier loads while maintaining comfort over smaller surface irregularities. This improves rear-end stability and reduces excessive oscillation.

A monotube gas-pressure architecture maintains consistent internal pressure and supports efficient heat dissipation. This helps reduce damping fade and ensures stable performance over extended driving and varied terrain.

Built with a durable monotube design, the shock minimizes oil aeration and maintains consistent damping over time. Its sealed internal structure is engineered for long-term reliability under continuous use and variable driving conditions.

Each shock is specifically tuned for the 2nd-Gen 4Runner platform, ensuring compatibility with factory suspension geometry. This calibration delivers balanced performance suitable for daily driving, towing, and light off-road use.
