Bilstein 87-93 Mustang Heavy Duty Shock (Rear)

Heavy Duty (HD) Bilsteins work very well in street applications with a variety of conventional springs. They are designed to deliver the best possible ride quality coupled with impressive street performance. The HD series dampers were not designed for use with overly aggressive spring rates. For dampers more suited to aggressive spring rates, see the MM Sport series and MM Race series dampers. 

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. Every Bilstein damper is tested on a shock dyno before leaving the factory to ensure quality.

All Bilstein struts and shocks include dustcovers suitable for use with conventional springs.

• Bilstein struts and shocks are made with patented mono-tube technology
• High nitrogen gas pressure prevents oil foaming and resultant fading
• Monotube design has better heat dissipation than twin-tube dampers, keeps the oil cooler, and decreases heat-induced damper fade
• Velocity-sensitive valving improves ride quality
• Each Bilstein strut and shock is tested on a shock dyno
• Not suitable for a coil-over conversion.
• Bilstein struts and shocks include dustcovers
• MM Sport series and MM Race series dampers are better suited for more aggressive spring rates.
