H&R 29580-2 Street Performance Coilover Kit Mono-Tube Adjustable Lowering

The H&R 29580-2 Street Performance Coilover Kit delivers a precisely engineered suspension upgrade for drivers who demand both improved handling and daily-drive comfort. Built around a mono-tube gas shock design, these coilovers offer superior damping response and more consistent performance compared to conventional twin-tube shock absorbers—making them an ideal choice for street use and occasional track days alike.

At the heart of the system, each shock is custom-valved to work in perfect harmony with H&R's precision-wound progressive rate springs, resulting in a finely tuned suspension that adapts to varying road conditions and driving styles. The fully threaded shock body provides true coilover-style height adjustment, allowing riders to dial in their exact desired stance without compromising ride quality.

Key Features:

• Mono-tube gas shock construction for precise handling response and consistent damping
• Progressive rate springs engineered to work in harmony with shock valving
• Adjustable ride height — average lowering range of 1.0 to 2.5 inches
• Fully threaded shock body for true coilover height adjustment via easy-to-use spring seats
• Galvanized steel construction for durable corrosion resistance
• Covers both front and rear axles
• Includes hook wrench for height adjustment
• 2-year warranty to the original purchaser
• TÜV approved

Professional installation is recommended, and a wheel alignment should be performed after fitment. The included H&R tech sheet specifies the allowable adjustment range — operating outside this range will void the warranty.
