H&R 50320 Street Performance Coilover System Mono-Tube Adjustable Lowering Kit

The H&R 50320 Street Performance Coilover System is engineered specifically for street-driven vehicles, delivering an exceptional balance of ride comfort and handling performance. Unlike conventional twin-tube shock absorbers, these coilovers utilize a state-of-the-art mono-tube gas shock construction that provides superior response, better heat dissipation, and more consistent damping under a wide range of driving conditions.

H&R is widely recognized as the originator of the true coilover system for street use, and the 50320 continues that legacy with precision engineering throughout. Each shock absorber is individually tuned and paired with a progressive rate spring designed from the ground up to complement the shock's specific valving characteristics — the result is a cohesive, finely calibrated suspension system rather than a mix-and-match assembly.

The fully threaded shock body allows for ride height adjustment without compromising suspension travel, giving drivers the flexibility to dial in their preferred stance while maintaining proper suspension geometry. With an average lowering range of 1.0 to 2.5 inches, these coilovers suit everyone from daily commuters seeking improved handling to enthusiasts looking for a more aggressive setup.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for consistent, fade-resistant damping
• Progressive rate springs — engineered specifically to match each shock's valving for a balanced, cohesive suspension tune
• Fully threaded shock body — allows precise, tool-adjustable ride height customization
• 1.0 to 2.5 inch average lowering range — suitable for mild street use through spirited performance driving
• Street-optimized tuning — designed to improve handling without sacrificing everyday ride comfort
• Complete coilover kit — includes all necessary hardware for installation

Whether used as a daily driver upgrade or as the foundation of a performance-oriented build, the H&R 50320 coilovers deliver the ride quality and handling precision that H&R's suspension engineers are renowned for worldwide.
