H&R 29358-2 Street Performance Monotube Coilover Kit

The H&R 29358-2 Street Performance Coilover Kit is a complete, vehicle-specific monotube coilover suspension system engineered to deliver a balance of sporty handling and daily-drive comfort. Unlike conventional twin-tube shock absorbers, these coilovers use a high-performance monotube gas shock design that provides more precise damping response and improved handling characteristics.

Each kit is 100% manufactured in Germany and certified to ISO 9001 quality standards and TÜV approval, reflecting H&R's decades of motorsport-derived engineering. The progressive-rate springs are individually matched and tuned to work in harmony with the shock valving — resulting in a cohesive, balanced suspension system rather than a collection of mismatched parts.

Key Features:

• Monotube gas shock absorbers for precise, responsive handling
• Inverted shock design reduces unsprung weight for improved wheel control
• Trapezoid-threaded shock body allows virtually infinite ride height adjustment
• Progressive-rate springs individually matched to shock valving for optimized street performance
• Front lowering range: 1.2" – 2.2"
• Rear lowering range: 0.75" – 1.7"
• Zinc-phosphate coated shock tubes for corrosion resistance and attractive finish
• Adjustment wrenches included
• All necessary hardware and installation instructions included
• ISO 9001 certified and TÜV approved
• Made in Germany

H&R Street Performance Coilovers lower the vehicle's center of gravity to reduce body roll during aggressive cornering, improving both handling precision and overall driving confidence. The fully threaded shock body — not a sleeve-over imitation — allows precise height adjustment to dial in stance, weight transfer, and suspension geometry without sacrificing ride quality.
