H&R 28851-2 Street Performance Coilover Kit

The H&R 28851-2 Street Performance Coilover Kit is a complete, height-adjustable suspension system engineered for street use. Hand-assembled in Germany by H&R Spezialfedern and built to meet ISO 9001 and TÜV quality standards, this coilover kit delivers a finely balanced combination of daily-driver comfort and serious handling performance.

At the heart of the system is a monotube gas shock design — a significant step up from traditional twin-tube shock absorbers. Each shock is custom-valved to work in precise harmony with a progressive rate spring, engineered from the ground up to complement the damper's specific valving characteristics. The result is a cohesive, purpose-built suspension system rather than a collection of mismatched parts.

The fully threaded shock body allows for broad, continuous ride height adjustment. Moving the threaded spring perch up or down fine-tunes stance and handling geometry simultaneously, lowering the vehicle's center of gravity and reducing body roll during hard cornering.

Key Features:

• Monotube gas shock construction for superior damping response
• Progressive rate springs custom-matched to each shock's valving
• Fully threaded shock body for adjustable ride height
• Approximate front lowering range: 1.5" – 2.3"
• Approximate rear lowering range: 1.1" – 2.0"
• Hand-assembled in Germany to ISO 9001 and TÜV standards
• 2-year manufacturer warranty
• Installs with standard hand tools and a spring compressor

Whether you're looking to sharpen up a daily driver or build a more performance-oriented street setup, the H&R 28851-2 coilovers offer the engineering depth and real-world tunability to get the job done right.
