H&R 29865-4 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29865-4 Street Performance Coilover Kit delivers a premium suspension upgrade engineered specifically for street use. Built around a state-of-the-art mono-tube gas shock construction, these coilovers outperform traditional twin-tube shock absorbers in both responsiveness and heat dissipation—making them an ideal choice for daily drivers and performance enthusiasts alike.

H&R is widely recognized as the originator of the true street coilover system, and the 29865-4 continues that legacy. Each shock absorber 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 superior performance over traditional twin-tube designs
• Fully threaded shock body allows precise, tool-adjustable ride height
• Lowering range of approximately 1.0 to 2.5 inches for a sportier stance without sacrificing daily drivability
• Progressive rate springs tuned in concert with shock valving for optimized handling and ride comfort
• Engineered for street use with balanced comfort and performance characteristics
• Suitable for daily drivers through serious performance tuners

H&R coilovers are built to exacting tolerances and backed by decades of suspension engineering expertise, making the 29865-4 one of the most trusted coilover solutions in the performance aftermarket.
