Product Information

Full details

The Koni Special Active 8745-1388 is designed for daily drivers and enthusiasts seeking a sophisticated balance between handling precision and ride comfort without the complexity of electronic systems. By utilizing Frequency Selective Damping (FSD) technology, these shocks automatically adjust their internal hydraulic resistance to smooth out road imperfections while firming up during spirited maneuvers; however, as a performance-oriented upgrade, they may feel noticeably stiffer than standard OE replacements on vehicles with very soft factory suspension setups.

FAQs

Do I need to wire these shocks into my car's computer?

No, the Koni Special Active line uses passive, mechanical FSD technology and requires zero electronic connections.

Can these shocks be used with lowering springs?

These dampers are primarily designed to work with original equipment or mild performance springs; consult the manufacturer if using aggressive lowering springs.

How often do they need to be serviced?

These are maintenance-free, sealed hydraulic units; they do not require user adjustment or fluid changes.

Will they make my car's ride harsh?

While firmer than stock, the FSD technology is specifically designed to maintain comfort on poor road surfaces.

Does the 8745-1388 fit both the front and rear?

No, this part number is specifically for the front application; always verify the part number for your specific vehicle's corner.

Troubleshooting

Noticeable clunking noise over small bumps

Check all mounting hardware torque specifications and inspect the top mount bushings for wear.

Vehicle feels unstable after installation

Verify that a professional wheel alignment has been completed and check that the springs are seated correctly.

Suspension feels too firm

Confirm the shocks are the correct part number for your specific vehicle weight class and confirm that no other suspension components are binding.

Pros and Cons

Pros

  • Automatic adjustment to road conditions without electronic complexity
  • Noticeable improvement in steering response and chassis stability
  • Comfortable ride quality on uneven surfaces
  • High-quality construction with excellent environmental protection

Cons

  • More expensive than standard hydraulic replacement shocks
  • Requires professional installation to ensure safety and alignment
  • May be firmer than standard factory-tuned dampers

Setup, Compatibility & Care

Installation of the Koni Special Active dampers should be performed by a qualified mechanic, as it involves the removal of the vehicle's suspension struts. After installation, a professional four-wheel alignment is mandatory to ensure tire longevity and predictable vehicle handling. Compatibility must be verified against the specific vehicle make, model, and production year to ensure the mounting points align correctly. For maintenance, regularly inspect the shocks for signs of hydraulic fluid leaks or damaged dust covers. While the units are treated for corrosion resistance, keeping the suspension area clean from heavy salt buildup during winter months will extend the aesthetic and functional lifespan of the exterior finish.
