H&R 50492 Street Performance Coilovers Mono-Tube Adjustable Lowering Kit

The H&R 50492 Street Performance Coilovers deliver a refined blend of everyday comfort and spirited handling for street-driven vehicles. Built around a mono-tube gas shock construction, these coilovers offer superior damping response and heat dissipation compared to traditional twin-tube designs — making them a proven upgrade for both daily drivers and enthusiast builds alike.

H&R pioneered the true coil-over system for street use and continues to set the benchmark in adjustable suspension. Each shock unit is individually tuned and paired with a progressive-rate spring engineered from the ground up to complement the shock's valving. The result is a cohesive, finely balanced suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction for precise, consistent damping performance
• Fully threaded shock body allows ride height adjustment to suit your preferences
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive-rate springs matched specifically to each shock's valving
• Engineered for street use — balances performance handling with daily-drive comfort
• Designed and tuned by H&R's suspension engineers

H&R coilovers are a direct upgrade over factory suspension, providing a noticeably lower stance, improved cornering stability, and a more connected driving feel without sacrificing the ride quality needed for everyday use.
