H&R 29480-4 Street Performance Coilovers Mono-Tube Adjustable Lowering Kit

The H&R 29480-4 Street Performance Coilovers deliver an exceptional balance of ride comfort and handling precision, engineered specifically for street-driven vehicles. Unlike conventional twin-tube shock absorbers, these coilovers utilize a mono-tube gas shock construction — a state-of-the-art design that provides superior heat dissipation, more consistent damping, and improved overall response compared to traditional setups.

H&R is widely recognized as the originator of the true coilover system for street use, and the 29480-4 continues that legacy. Each shock unit is individually valved and paired with a progressive-rate spring engineered from the ground up to complement the shock's specific damping characteristics. The result is a cohesive, finely tuned suspension system rather than a collection of mismatched components.

Key Features:

• Mono-tube gas shock construction — superior to traditional twin-tube designs for heat management and consistent performance
• Fully threaded shock body for precise, tool-adjustable ride height lowering
• Lowering range of approximately 1.0 to 2.5 inches — dial in your preferred stance without sacrificing driveability
• Progressive-rate springs matched specifically to each shock's valving for optimized ride and handling
• Designed for everyday street use as well as performance-oriented driving
• Engineered and tuned by H&R's suspension specialists

Whether you're a daily driver looking to improve your vehicle's stance and handling, or an enthusiast seeking a more performance-focused suspension upgrade, the H&R 29480-4 Street Performance Coilovers offer a proven, premium solution backed by decades of suspension engineering expertise.
