Bilstein 26-328706 B4 Series OE Replacement Shock Absorber

The Bilstein 26-328706 is a B4 Series monotube shock absorber engineered as a direct OE replacement, delivering the same precise ride quality and handling characteristics as the original factory shock. Designed for drivers who want to restore like-new suspension performance without sacrificing comfort or control, the B4 Series is Bilstein's benchmark for OEM-grade replacement dampers.

Bilstein's proprietary monotube gas-pressure technology separates it from conventional twin-tube designs. A high-pressure nitrogen gas charge works in conjunction with a single working cylinder to provide consistent, fade-free damping response under all road conditions — from daily commuting to long highway drives.

Key Features:

• Monotube, gas-pressure shock absorber design for superior damping consistency
• Direct OE replacement — no modifications required for installation
• Self-adjusting velocity-sensitive valving adapts to changing road conditions
• Zinc-coated body and chrome-finished piston rod for corrosion resistance
• Seamless steel pressure tube for long-term durability
• Manufactured to OEM specifications for precise fit and function
• Bilstein's stepless, digressive damping force curve for optimal comfort and control

The B4 Series shock is built in Bilstein's ISO-certified manufacturing facilities and meets or exceeds original equipment standards. It is an ideal choice for restoring factory-spec suspension feel on passenger cars and light-duty vehicles. Each unit is ready to install and backed by Bilstein's reputation for German-engineered performance.
