H&R 29271-1 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29271-1 Street Performance Coilovers are precision-engineered for everyday street use without sacrificing handling performance. Featuring a state-of-the-art mono-tube gas shock construction, these coilovers outperform traditional twin-tube shock absorbers by delivering more consistent damping, better heat dissipation, and improved response across a wide range of driving conditions.

H&R is widely recognized as the originator of the true street coilover system, and the 29271-1 reflects decades of suspension engineering expertise. Each shock unit is individually tuned with a progressive rate spring designed from the ground up to complement the shock's internal valving — resulting in a cohesive, finely balanced suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for heat management and consistent performance
• Fully threaded shock body for precise, tool-adjustable ride height lowering
• Lowering range of approximately 1.0 to 2.5 inches for a sportier stance and improved center of gravity
• Progressive rate springs engineered specifically to match each shock's valving for optimal ride quality
• Suitable for daily drivers through serious performance enthusiasts
• Uncompromised balance of ride comfort and handling precision

H&R Coilovers are manufactured to exacting tolerances and represent a complete suspension solution — not just a lowering spring. Whether building a comfortable daily driver or a performance-tuned street car, the H&R 29271-1 delivers a measurable upgrade over stock suspension components.
