H&R 28850-11 Street Performance Coilover Kit

The H&R 28850-11 Street Performance Coilover Kit is a complete, height-adjustable suspension system engineered for street use. Built around a mono-tube gas shock design, these coilovers deliver superior damping control and stable damping characteristics in all driving conditions — a significant upgrade over traditional twin-tube shock absorbers.

H&R pioneered the true coilover system for street applications, and the Street Performance line reflects decades of suspension engineering expertise. Each shock is custom-valved to work in harmony with a precision-engineered progressive-rate spring, creating a balanced suspension system that is responsive under hard driving yet comfortable during daily use. The fully threaded shock body — a true threaded design, not a damper insert in a threaded sleeve — allows for precise ride height adjustment, helping lower the vehicle's center of gravity for improved performance and handling dynamics.

Key Features:

• Mono-tube gas shock construction for superior damping and reduced unsprung weight
• Fully threaded shock body for precise, adjustable ride height
• Custom-valved dampers paired with progressive-rate springs for a finely tuned system
• Front lowering range: 0.75" – 1.6" | Rear lowering range: 0.70" – 1.4"
• TÜV tested and manufactured to exceed ISO quality standards
• 2-year warranty to the original purchaser
• Complete front and rear kit

The H&R 28850-11 is an ideal suspension upgrade for drivers who want a lower stance and sharper handling without sacrificing everyday ride quality. Professional installation and a post-install alignment are recommended.
