H&R 28981-1 Street Performance Coilover Kit

The H&R 28981-1 Street Performance Coilover Kit delivers an exceptional balance of ride comfort and handling precision for drivers who demand more from their suspension. Built on a mono-tube gas shock construction, these coilovers outperform traditional twin-tube designs by providing a more responsive and consistent damping force under a wide range of driving conditions.

H&R pioneered the true street coilover system and continues to lead the market with application-specific engineering. Each shock is custom-tuned to work in harmony with a precision-wound progressive rate spring, creating a cohesive suspension system rather than a collection of off-the-shelf parts. Units are hand-assembled in Germany under strict ISO 9001 and TÜV standards, ensuring consistent quality and long-term durability.

Key Features:

• Mono-tube gas shock construction for superior handling response over traditional twin-tube designs
• Fully threaded shock body allows virtually infinite ride height adjustment via adjustable spring perches
• Lowering range of approximately 1.0" to 2.5" on average (front and rear vary by application)
• Progressive rate springs precisely matched to each shock's valving for a finely tuned ride
• Engineered and hand-assembled in Germany to ISO 9001 and TÜV standards
• Zinc-phosphate coated shock tubes for corrosion resistance and lasting finish
• Suitable for daily drivers through serious performance enthusiasts

The H&R Street Performance Coilover Kit is a complete, vehicle-specific suspension solution that replaces both the OEM springs and shock absorbers. The externally threaded body design allows the spring perch to be raised or lowered to fine-tune ride height, optimizing both stance and handling without compromising suspension geometry.
