H&R 50402 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 50402 Street Performance Coilover Kit is engineered specifically for street use, delivering a refined balance of daily-drive comfort and spirited handling. Unlike conventional twin-tube shock absorbers, these coilovers feature a state-of-the-art mono-tube gas shock construction that provides superior heat dissipation, more consistent damping response, and improved ride quality over a wide range of driving conditions.

H&R is widely recognized as the originator of the true coilover system for street applications and continues to set the benchmark for quality and performance. Each shock absorber is individually tuned with a progressive rate spring engineered from the ground up to complement the shock's internal valving — resulting in a cohesive, finely balanced suspension system rather than a collection of mismatched components.

The fully threaded shock body allows precise, tool-adjustable ride height customization, giving drivers the flexibility to dial in their preferred stance and handling characteristics without compromising ride quality. With an average lowering range of 1.0 to 2.5 inches, this kit suits everyone from daily commuters to dedicated performance enthusiasts.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for consistent, fade-resistant damping
• Progressive rate springs — matched and tuned specifically to each shock's valving for optimal performance
• Fully threaded shock body — allows precise, adjustable ride height without spring preload compromise
• Average lowering range of 1.0 to 2.5 inches — adaptable to a variety of ride height preferences
• Street-tuned valving — engineered for comfort and performance on public roads
• Suitable for daily drivers and performance-oriented enthusiasts alike

H&R coilover systems are manufactured to exacting standards and are a trusted upgrade for drivers seeking improved handling dynamics, a lower center of gravity, and a more responsive suspension feel without sacrificing everyday usability.
