H&R 29375-1 Street Performance Coilover System

The H&R 29375-1 Street Performance Coilovers deliver an exceptional balance of daily-driving comfort and precision handling. Engineered specifically for street use, these coilovers feature a monotube gas shock construction — a significant upgrade over traditional twin-tube shock absorbers — providing superior damping response, improved heat dissipation, and consistent performance mile after mile.

H&R is widely recognized as the originator of the true street coilover system, and the 29375-1 upholds that legacy. Each shock is individually tuned and paired with a progressive-rate spring designed from the ground up to complement the shock's specific valving. The result is a cohesive, finely calibrated suspension system — not an off-the-shelf combination of mismatched components.

Key Features:

• Monotube gas shock construction for superior performance over traditional twin-tube designs
• Fully threaded shock body allows precise, tool-adjustable ride height setting
• Adjustable lowering range of approximately 1.0 to 2.5 inches
• Progressive-rate springs engineered specifically to match each shock's valving
• Optimized for both daily drivers and performance-oriented builds
• Uncompromised ride comfort without sacrificing handling precision

Whether you're looking to improve cornering response, achieve a more aggressive stance, or simply upgrade aging factory suspension, the H&R 29375-1 coilovers are a complete, street-ready solution backed by decades of H&R suspension engineering expertise.
