Bilstein 24-120227 B8 Performance Plus Monotube Suspension Shock Absorber for Lowered Vehicles - 36mm

The Bilstein 24-120227 B8 Performance Plus is a high-performance monotube shock absorber engineered as a direct upgrade over factory dampers, specifically optimized for use with aftermarket lowering springs and OE sport suspension setups. Built with Bilstein's renowned precision and durability, this damper delivers sharper handling response and a sportier driving character without sacrificing everyday drivability.

Featuring a 36mm monotube gas-pressure design, the B8 Performance Plus uses a shortened body — approximately 20mm less extended length than a standard shock — to ensure proper spring preload when paired with lowering springs. Application-specific valve tuning is developed and validated through real-world Bilstein road testing, resulting in a damper characteristic curve precisely matched to the target vehicle platform.

Key Features:

• Monotube gas-pressure technology for consistent, fade-free damping performance
• Shortened design ensures correct spring preload and geometry when used with lowering springs
• Application-specific valving individually fine-tuned during Bilstein road testing
• Seamless extruded shock body provides superior strength, heat dissipation, and extended service life
• Dividing piston allows oil to expand under heat, preventing aeration and maintaining damping consistency
• Meets or exceeds OE quality standards — manufactured in Germany
• Compatible with aftermarket lowering spring kits and factory sport suspension systems
• Backed by Bilstein's limited lifetime warranty

The Bilstein B8 Performance Plus is sold individually. It is the ideal performance damper solution for drivers seeking improved handling dynamics, precise vehicle control, and a sportier stance when combining with a lowering spring upgrade.
