H&R 29524-4 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29524-4 Street Performance Coilovers are precision-engineered for enthusiasts who demand superior handling without sacrificing everyday ride quality. Built around a mono-tube gas shock design, these coilovers deliver more consistent damping performance and improved heat dissipation compared to traditional twin-tube shock absorbers — making them equally at home on daily commutes and spirited canyon runs.

H&R is widely recognized as the originator of the true street coilover system, and the 29524-4 reflects decades of suspension engineering expertise. Each shock unit is individually tuned and paired with a progressive-rate coil spring designed from the ground up to complement the shock's specific valving characteristics. 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 damping response and thermal management
• Fully threaded shock body allows precise, tool-adjustable ride height lowering
• Lowering range of approximately 1.0 to 2.5 inches below factory ride height
• Progressive-rate springs engineered specifically to match each shock's valving
• Optimized for street use — balances performance handling with daily driver comfort
• Suitable for a wide range of drivers, from everyday commuters to serious tuning enthusiasts

H&R coilovers are manufactured to strict quality standards and are backed by H&R's long-standing reputation in the performance suspension market. The 29524-4 kit provides a straightforward path to improved cornering, reduced body roll, and a lower, more aggressive stance.
