H&R 50151 Street Performance Coilovers Mono-Tube Adjustable Lowering Kit

The H&R 50151 Street Performance Coilovers deliver a premium suspension upgrade engineered specifically for street-driven vehicles. Built around a mono-tube gas shock design, these coilovers offer superior heat dissipation, more consistent damping response, and a smoother overall ride compared to conventional twin-tube shock absorbers.

H&R is widely recognized as the originator of the true street coilover system, and the 50151 upholds that legacy. Each shock absorber is individually valved and paired with a progressive-rate coilover spring that is engineered from the ground up to complement the shock's specific damping characteristics — the result is a cohesive, finely balanced suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction for consistent, fade-resistant damping performance
• Fully threaded shock body allows precise, tool-adjustable ride height
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive-rate springs matched to shock valving for optimized ride and handling balance
• Engineered for daily driving comfort as well as spirited performance use
• Manufactured to H&R's OEM-grade quality standards

Whether you're a daily commuter looking to sharpen your vehicle's stance and road manners, or an enthusiast seeking genuine performance gains without sacrificing ride quality, the H&R 50151 Street Performance Coilovers represent one of the most complete suspension solutions available for street use.
