The Bilstein 07-14 Toyota FJ Cruiser / 03-24 Toyota 4Runner B8 5100 Rear 46mm Monotube Shock Absorber is engineered for direct OE-style fitment and dyno-tested performance gains. Below are the technical details, fitment notes, and what's included.

Bilstein is the world's premier monotube gas-pressure shock specialist and an OE supplier to Porsche, Mercedes-Benz, BMW, and many other premium automakers. Their B6, B8 5100, B14, and B16 series cover everything from OEM-replacement comfort to full coilover performance — all built to last with the patented Bilstein digressive valving that keeps the ride composed without sacrificing comfort.

Key features:

• Monotube gas-pressure design — superior heat dissipation vs. twin-tube
• Digressive valving for composed handling without harshness
• OE supplier-grade construction — same components used on Porsche, BMW & Mercedes-AMG
• 5100 series fits factory ride height; B8 series for lifted/lowered applications
• Made in Germany or USA (Hamilton, OH) — never offshore
• Backed by the Bilstein Limited Lifetime Warranty

Pick by series: B6 = OE replacement | B8 5100 = lift-friendly | B14 = coilover ride-height adjustable | B16 = damping-adjustable performance.
