Tech
Heavy Duty (HD) Bilsteins work very well in street applications with a variety of both conventional springs and coil-over conversions. They are designed to deliver the best possible ride quality coupled with impressive street performance. 

While they are non-adjustable, Bilstein's unique deflective-disc valve design instantaneously self-adjusts to changing road surfaces. Their performance does not degrade with age, usage, or heat, requiring no compensating manual adjustments as with other brands. Bilstein uses a patented mono-tube design that allows for a larger piston size than is possible with a twin-tube damper. The mono-tube design provides better heat dissipation to keep the damper's oil cooler, and decreases heat-induced damper fade. High-pressure nitrogen gas prevents oil foaming and fading. The unique inverted design of the Bilstein strut allows for very large strut shaft bushings, which are less prone to deflection. The inverted strut design also keeps the oil seal protected from the elements. Every Bilstein damper is tested on a shock dyno before leaving the factory to ensure quality. 

These Bilstein struts and shocks include dustcovers.
