Refresh and upgrade you A4 platform TDI with this IDParts exclusive KONI + Suplex Kit.  This kit comes with Koni Special aka Koni Red shocks along with a full set of springs of your choosing.

The Koni Specials are a perfect fit to upgrade the VW suspension and provide the best ride comfort with improved handling and durability. The twin tube hydraulic dampers have been called the "best alternative to stock" because they provide much improved handling while retaining exceptional ride quality. They are also rebuildable, and adjustable to compensate for wear.

SUPLEX springs are made in Germany to OEM specifications.  Unlike other aftermarket springs that use a one-size-fits-all approach, SUPLEX makes springs that are exact OE-rate per model and engine.

Choose your model configuration below.  Configurations include:

  • Traditional Configurations - for Golf, Jetta Sedan, New Beetle options include OE rate springs and the Koni Special A4 Set.  The Jetta Wagon configuration comes with Wagon Springs and Koni Specials for Jetta Wagon.
  • HD Configurations - all HD configurations come with VR6 Front Springs and Towing/HD Rear springs along with the Koni Special for Jetta Wagon Set.  The Koni wagon rears are longer and are valved slightly stiffer to accomodate the higher rate rear springs.

 Optional Upgrades:

  • Front and rear mounts are often worn out and should be replaced whenever refreshing the suspension
  • Bump stops protect the shock from damage during large impacts like potholes.  If they are in good condition they can be re-used, but they should be replaced if cracked or degraded
  • Installation bolt kit includes all the major hardware that secures the suspension to the vehicle.  It is recommended to replace whenever removed, but certainly replace if corroded/rusty.

Get front or rear mounts for half price when selecting them as options below.

Frequently Asked Questions

The Wagon HD option is the same as the SUPLEX Lift spring kit for the Jetta Wagon.
If you are looking for the most ride height increase, choose the Jetta Wagon HD option. This will fit on Golfs & Jetta sedans, however, the rear shocks may top-out when going over sharp drops like speed bumps, so we don't really recommend it. It will also cause Golfs & sedans to nose-dive, so we recommend adding the 10mm spacers if going with the Jetta Wagon HD kit.
