H&R 39220-1 Premium Performance Coilover Kit - Mono-Tube, Adjustable Height, Aluminum Struts

The H&R 39220-1 Premium Performance Coilover Kit builds on the acclaimed H&R Street Performance platform, adding ultra-lightweight aluminum front struts engineered to deliver a measurable reduction in unsprung weight and a noticeable improvement in ride dynamics. Designed for street use, this kit combines German engineering precision with race-derived mono-tube gas shock construction for a suspension upgrade that excels in both daily driving and spirited performance.

At the core of the Premium Performance design is the mono-tube gas shock, which offers superior damping response compared to conventional twin-tube absorbers. Each shock is custom-valved and paired with a progressive-rate spring, creating a finely balanced suspension system that maintains ride comfort at any ride height setting.

Key Features:

• Aluminum front struts reduce unsprung weight 30–40% over stock struts for sharper suspension response
• Black hard-anodized aluminum finish provides corrosion resistance, added strength, and a clean aesthetic
• Mono-tube gas shock construction delivers consistent, race-derived damping performance
• Fully threaded shock body allows easy ride height adjustment via spring seat collars
• Adjustable lowering range of approximately 1.0 to 2.5 inches on average (front: 1.2–2.3 in., rear: 1.0–2.0 in.)
• Progressive-rate springs front and rear for optimized ride quality at all height settings
• Fits 55mm front strut clamp applications
• Lowers center of gravity to reduce body roll and improve cornering stability

The H&R 39220-1 Premium Performance Coilover Kit is an ideal choice for performance-minded drivers who want the handling benefits of a true coilover system without sacrificing everyday ride quality. Height adjustment accommodates seasonal preferences or personal stance goals, giving you full control over your vehicle's setup.
