H&R 29040-2 Street Performance Coilover Kit - Monotube Gas Shock System

The H&R 29040-2 Street Performance Coilover Kit delivers a precisely engineered suspension upgrade designed for drivers who demand both improved handling and daily-driving comfort. Unlike conventional twin-tube shock absorbers, these coilovers utilize a monotube gas shock construction — the same technology derived from H&R's motorsport heritage — for more responsive damping, better heat dissipation, and superior handling precision.

Each shock absorber is individually custom-valved to work in direct harmony with a precision-engineered progressive rate spring, creating a fully integrated suspension system rather than a collection of mismatched components. The progressive spring rate provides a compliant ride over everyday road imperfections while stiffening progressively under hard cornering, braking, or acceleration loads.

Key Features:

• Monotube gas shock absorbers for precise, responsive handling behavior front and rear
• Inverted strut design reduces unsprung weight for improved wheel control and steering response
• Fully threaded shock body with trapezoid threads allows virtually infinite ride height adjustment
• Zinc-phosphate coated shock tubes provide corrosion resistance and a clean, durable finish
• Approximate front lowering range: 1.2 – 2.3 inches
• Approximate rear lowering range: 1.1 – 2.3 inches
• Progressive rate springs engineered and matched specifically to the shock valving
• Engineered and manufactured in Germany to H&R's exacting quality standards

The fully threaded shock body gives you the flexibility to fine-tune ride height for your preferred stance and driving style — whether you want a modest street drop or a more aggressive lowered setup. H&R coilovers are a complete, matched system engineered to work together, delivering balanced performance that generic part combinations simply cannot replicate.
