H&R 50418-2 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 50418-2 Street Performance Coilover Kit delivers a premium suspension upgrade engineered specifically for street-driven vehicles. Built around a state-of-the-art mono-tube gas shock construction, this system offers superior performance and response compared to conventional twin-tube shock absorbers — providing a finely balanced combination of ride comfort and handling precision.

H&R pioneered the true coilover system for street use and continues to set the standard with meticulously engineered suspension solutions. Each shock absorber in this kit is paired with a progressive rate spring that is designed from the ground up to complement the shock's valving characteristics, resulting in a cohesive, fully integrated suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction — advanced design for superior heat dissipation and consistent damping performance
• Fully threaded shock body — allows precise, tool-accessible ride height adjustment
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive rate springs — engineered in tandem with shock valving for optimal performance
• Street-tuned valving — balanced for daily driving comfort and spirited performance driving
• Suitable for daily drivers through serious enthusiast builds

The H&R 50418-2 coilover kit is an ideal solution for drivers seeking a noticeable improvement in both handling dynamics and vehicle stance without sacrificing the ride quality expected from a street-driven suspension system.
