H&R 29974-1 Street Performance Monotube Coilover Kit

The H&R 29974-1 Street Performance Coilover Kit is a premium, German-engineered suspension system built for drivers who demand a perfect balance of ride comfort and performance. Unlike conventional twin-tube designs, these coilovers are built around a monotube gas shock construction that delivers superior damping response and more precise handling dynamics on the street.

Each shock absorber is custom-valved to work in direct harmony with a precision-engineered progressive rate spring, resulting in a finely tuned suspension system that stays composed whether you're commuting daily or pushing hard through corners. The fully threaded shock body provides virtually infinite ride height adjustment, allowing you to dial in the perfect stance and weight balance for your driving style and conditions.

Key Features:

• Monotube gas shock absorbers for precise, consistent damping response
• Inverted shock design reduces unsprung weight for improved handling and wheel control
• Fully threaded shock body with trapezoid thread for virtually infinite, corrosion-resistant height adjustment
• Progressive rate springs engineered to complement the shock valving for a balanced ride at any height setting
• Zinc-phosphate coated shock tubes provide corrosion protection and a clean finish
• Average front lowering of 1.5" – 2.25"; average rear lowering of 1.25"
• Sold as a complete front and rear kit
• 100% engineered and manufactured in Germany

H&R Street Performance Coilovers lower the vehicle's center of gravity, reducing body roll during hard cornering and improving overall balance and control. Suitable for daily drivers and enthusiast tuners alike, these coilovers deliver race-derived suspension technology in a package fully optimized for street use.
