Volvo Strut Insert - Koni Sport 8641 1246

Product Information

A suspension strut cartridge is the internal shock-absorbing component housed within a strut assembly. It controls suspension movement by dampening the up-and-down motion of the springs, ensuring stability, comfort, and proper tire contact with the road. In some vehicles, the cartridge can be replaced separately without changing the entire strut housing.

• Excessive bouncing or poor ride comfort, as the cartridge can no longer dampen spring movement effectively.
• Nose-diving or body roll, especially during braking or cornering, due to weakened damping control.
• Fluid leaks or clunking noises, indicating internal seal failure or worn-out cartridge components.

What is the best adjustment setting for my shocks?

There is no single best adjustment setting for your KONIs because every driver has different preferences for comfort, performance, performance modifications and roads to drive on. For most vehicles, we suggest that new KONIs be installed in the full soft position. (the standard setting right out of the box) to take advantage of the balance of ride comfort and handling designed by the KONI ride development engineers. If the car has performance upgrades (springs, wheel/tire packages, etc.) or the driver wants the car a bit more aggressive, most people find the optimum setting in the 1/2 to one full turn from the full soft range. Over the extended life of the damper or if the driver wants a specific firm handling characteristic, the dampers can be adjusted up higher. Very rarely will KONI ever need to be adjusted to the full firm setting.

What are the best springs to match my KONIs?

One of the great advantages of KONI adjustable shocks is that there is no specific spring for matching optimum performance. Instead you can adjust your KONIs to match your springs. Most performance springs have a higher spring rate than the vehicle's original springs. Since the shock controls the motion of the spring, increased spring rates require more rebound damping for control and that is one of the reasons why KONIs are rebound adjustable (and some are double adjustable). Using higher rate springs with OE or soft shocks will very quickly overcome and wear out the shocks. The KONI adjustment range is typically about 100% (twice as firm at the full firm settings at the full soft setting) to allow for proper damping of OE springs and high rate performance springs.
