H&R 28851-14 Street Performance Coilovers Mono-Tube Adjustable Lowering Kit

The H&R 28851-14 Street Performance Coilovers are engineered from the ground up for street-driven vehicles that demand a superior balance of ride comfort and handling performance. Unlike conventional twin-tube shock absorbers, these coilovers feature a state-of-the-art mono-tube gas shock construction that delivers more precise damping response, better heat dissipation, and improved overall suspension feel.

H&R is widely recognized as the originator of the true street coilover system, and the 28851-14 continues that legacy. Each shock unit is individually valved and paired with a progressive-rate coil spring engineered specifically to complement that valving — the result is a finely integrated suspension system rather than a collection of mismatched components. The fully threaded shock body allows for straightforward ride-height adjustment without compromising spring preload or shock function.

Key Features:

• Mono-tube gas shock construction for superior damping performance over twin-tube designs
• Fully threaded shock body for precise, adjustable vehicle lowering
• Progressive-rate springs tuned specifically to match each shock's valving characteristics
• Lowering range of approximately 1.0 to 2.5 inches for a sportier stance and improved center of gravity
• Engineered for daily-driven street vehicles as well as performance-oriented builds
• Designed and developed by H&R's in-house suspension engineers

Whether you're a daily commuter looking to sharpen up your vehicle's dynamics or an enthusiast seeking a more aggressive stance without sacrificing ride quality, the H&R 28851-14 Street Performance Coilovers deliver a factory-quality upgrade with proven engineering behind every component.
