Volvo V70/XC70 2001-2007 » Shocks & Struts (Bilstein)

Bilstein Heavy Duty

The choice for the truly discriminating driver, Bilstein HDs offer handling so superior, they're capable of damping wheel movement as small as 2mm. And that's smooth.

Most stock shocks just don't have enough damping on compression and rebound. The result is mushy transitional performance, brake dive, choppy feel on expansion joint and in some cases, suspension crash through.

Explaining how Bilstein HDs improve ride with increased damping is difficult. How can the ride be smoother and feel plusher if the shock is stiffer? A big part of improvement comes from Bilstein's patented digressive valving system that helps soak up initial shock loads before full damping is achieved. This takes off the edge of most impacts and completely changes the feel of the car. An unusually high number of customers have called back with praise of Bilsteins. One customer went so far as to say, "You guys are too subtle in your ads for these things, you've got to let people know that this is the fix!"
