H&R 54704 Street Performance Coilover Suspension Kit

The H&R 54704 Street Performance Coilovers are precision-engineered for daily street use without sacrificing handling performance. Unlike conventional twin-tube shock absorbers, these coilovers utilize a mono-tube gas shock construction that delivers superior damping response and more consistent performance across a wide range of driving conditions.

H&R pioneered the true coil-over system for street applications and continues to set the standard with an extensive catalog of vehicle-specific applications. Each shock absorber is individually tuned and paired with a progressive rate spring engineered specifically to complement the shock's internal valving — resulting in a cohesive, finely balanced suspension system rather than a mismatched assembly of off-the-shelf components.

Key Features:

• Fully threaded shock body allows precise, tool-assisted ride height adjustment
• Adjustable lowering range of approximately 1.0 to 2.5 inches on average
• Mono-tube gas shock construction for improved heat dissipation and consistent damping
• Progressive rate springs matched to each shock's valving for optimal ride and handling balance
• Engineered for street use — suitable for daily drivers through serious performance enthusiasts
• Superior comfort and handling over OEM suspension components

H&R's Street Performance Coilovers offer a compelling upgrade for drivers seeking lower ride height, improved cornering response, and a more planted feel — all while retaining the comfort required for everyday use.
