H&R 29316-1 Street Performance Coil-Over Spring Kit

The H&R 29316-1 Street Performance Coil-Over Spring is engineered specifically for street-driven vehicles, combining everyday comfort with genuine performance handling. Built around a state-of-the-art mono-tube gas shock construction, this coil-over system delivers superior response and control compared to conventional twin-tube shock absorbers.

H&R is widely recognized as the originator of the true street coil-over system, and the 29316-1 reflects decades of suspension engineering expertise. Each unit is precisely tuned with a progressive rate spring designed from the ground up to work in harmony with the shock's internal valving — resulting in a cohesive, finely balanced suspension system rather than mismatched aftermarket components.

Key Features:

• Mono-tube gas shock construction for superior heat dissipation and consistent damping performance
• Fully threaded shock body allows precise, adjustable ride height lowering
• Average lowering range of 1.0 to 2.5 inches for an aggressive stance without sacrificing drivability
• Progressive rate spring tuned to match shock valving for a seamless ride quality
• Engineered for both daily drivers and performance enthusiasts
• Improved handling, cornering stability, and ride comfort over stock suspension

The H&R 29316-1 coil-over system is an ideal upgrade for drivers seeking a meaningful improvement in vehicle dynamics — delivering a lower center of gravity, reduced body roll, and a sportier driving experience while remaining fully street-legal and comfortable for daily use.
