H&R 54767 Street Performance Coilovers Mono-Tube Adjustable Lowering System

The H&R 54767 Street Performance Coilovers deliver a premium suspension upgrade engineered specifically for street use. Unlike conventional twin-tube shock absorbers, these coilovers are built around a state-of-the-art mono-tube gas shock construction, providing superior damping response, reduced fade, and improved heat dissipation compared to traditional designs.

H&R is recognized as the originator of the true coil-over system for street applications and continues to set the benchmark for performance suspension. Each unit 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 that performs as a unified assembly rather than mismatched components.

The fully threaded shock body allows precise, tool-adjustable ride height lowering, giving drivers the flexibility to dial in their preferred stance and handling characteristics. Whether used as a daily driver upgrade or as the foundation of a serious performance build, the H&R 54767 coilovers offer an exceptional balance of comfort and cornering capability.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for heat management and consistent damping
• Fully threaded shock body for tool-adjustable, customizable ride height
• Lowering range of approximately 1.0 to 2.5 inches (average; varies by application)
• Progressive rate springs tuned specifically to match each shock's valving
• Designed for street use — balances everyday ride comfort with enhanced handling performance
• Engineered and developed by H&R's suspension specialists

H&R coilovers are a trusted choice for enthusiasts seeking a meaningful suspension upgrade that improves both aesthetics and driving dynamics without sacrificing daily drivability.
