H&R 39471-1 Premium Performance Coilover Kit - Aluminum Mono-Tube Height Adjustable

The H&R 39471-1 Premium Performance Coilover Kit elevates the benchmark for street suspension systems by combining H&R's legendary mono-tube gas shock engineering with ultra-lightweight aluminum front strut bodies. Built on the same platform as the acclaimed H&R Street Performance coilover line, the Premium kit takes things further with a construction refinement that meaningfully improves handling dynamics and unsprung weight.

Each front strut body is crafted from aluminum and black hard anodized for exceptional corrosion resistance, long-term durability, and a clean factory-finished appearance. The aluminum construction delivers a 30–40% weight reduction over stock struts, directly improving suspension articulation and response. The fully threaded shock body allows for precise, tool-adjustable ride height, letting you dial in the ideal balance between aggressive stance and optimal weight transfer.

Under the skin, H&R's exclusive dynamic damper technology pairs each custom-valved mono-tube gas shock with a vehicle-specific progressive-rate spring, engineered from the outset to work in harmony with the shock's valving. The result is a finely tuned suspension system that delivers improved handling and superb ride comfort without sacrifice. 100% made in Germany, these coilovers meet and exceed ISO quality assurance standards.
