H&R 29363-2 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29363-2 Street Performance Coilovers are engineered specifically for street use, delivering a refined balance of ride comfort and improved handling. Built around a mono-tube gas shock construction, these coilovers outperform traditional twin-tube shock absorbers in heat dissipation, response, and consistency — making them ideal for daily drivers and enthusiast tuners alike.

H&R is widely recognized as the originator of the true street coilover system, and the 29363-2 reflects decades of suspension engineering expertise. Each shock is precisely valved and paired with a progressive rate spring designed from the ground up to work in harmony with the shock's internal valving. The result is a cohesive, finely tuned 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-based ride height adjustment
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive rate springs engineered specifically to match each shock's valving
• Optimized for street use — balancing everyday comfort with enhanced handling
• Suitable for daily drivers through serious performance enthusiasts

H&R coilovers are a proven suspension upgrade for drivers who want meaningful lowering and improved dynamics without sacrificing the ride quality needed for regular street driving.
