H&R 29954-2 Street Performance Coilover Kit - Mono-Tube Gas Shock, Adjustable Ride Height

The H&R 29954-2 Street Performance Coilover Kit delivers a premium suspension upgrade engineered specifically for street use. Unlike conventional twin-tube shock absorbers, these coilovers are built around a mono-tube gas shock design that provides superior heat dissipation, more consistent damping response, and improved overall handling feel compared to standard OEM suspension.

H&R pioneered the true street coilover system and remains an industry leader in suspension engineering. Each shock is precisely matched with a vehicle-specific progressive rate spring, tuned from the ground up to work in harmony with the shock's valving. The result is a cohesive, balanced suspension system — not a mix of mismatched components.

Key Features:

• Mono-tube gas shock construction for precise, fade-resistant damping performance
• Fully threaded shock body with trapezoid-threaded spring seats for near-infinite ride height adjustability
• Progressive rate coil springs engineered to complement shock valving for optimal balance of comfort and control
• Adjustable lowering range — approximately 1.0" to 2.0" front and rear
• Complete coilover system — all components matched and tuned to work together
• Suitable for daily drivers and performance enthusiasts alike

Whether you're looking to improve cornering grip, reduce body roll, or achieve a more aggressive stance without sacrificing ride quality, the H&R 29954-2 coilovers offer the flexibility and engineering precision to meet your goals straight out of the box.
