Performance Drop in Strut/Lowering Spring Combo

*Does not fit V8 W-body vehicles


  • (4) Struts
  • (4) ZZP Coil springs
  • (4) New strut boots
  • (4) New Rubber isolators (spring pads)
  • (4) New top plates
  • (4) Top plate "anti pogo" washers

This is a complete drop in replacement suspension for your W-body. Choose from either the KYB GR2 or the adjustable AGX strut. This will lower the car 2" in the front and 1 1/2" in the rear. Since the car is lowered, we highly recommend our shorter dog bones (ZZP Billet or Standard) to correct axle angle.  This setup will dramatically improve your cars handling, to improve it even more, look into the ZZP Front and rear sway bars and our chromoly trailing arms as well.

AGX not available for 04-05 Grand Prix without installing the 97-03 front control arms/sway bar bushings.

Worked as advertised

Very happy with the product rides a little stiffer than stock but that is to be expected when you lower any vehicle. Easy install.
