Product Details

The Swift Sport Lowering Springs for the 2006-2013 Lexus IS350 RWD (GSE21L) close the wheel gap on the IS350 and deliver the handling sharpness that the 3.5L V6 deserves. These IS350 lowering springs provide an approximate 1.0" front and 0.8" rear drop, designed to work with the stock adaptive dampers for a sport-tuned yet refined ride. Built in Japan from Swift's proprietary H5S.TW spring steel, these IS350 springs reduce body roll and improve weight transfer for more confident cornering and a visually sportier presence.

Swift Sport Spring Technology

  • Proprietary H5S.TW high-tensile spring steel, manufactured in Japan
  • Designed to lower within each vehicle's usable shock stroke range
  • Fewer coils reduce unsprung mass and eliminate coil bind
  • Quicker transient response for a smoother ride over rough surfaces
  • Vehicle-specific tuning preserves each car's intended ride character
  • Bump rubber integration prevents suspension bottoming out

Features

  • Sportier stance with reduced wheel gap
  • Improved handling with reduced body roll
  • Comfortable ride quality preserved for daily driving
  • Lower center of gravity for better cornering confidence
  • Compatible with OEM and aftermarket shocks/struts
  • Direct bolt-on installation with no modifications required

    Swift Springs.

    These Springs are like OEM but stiffer on the rebound? Which Gives you control and a stable ride and it also gives you a low stand without bottom out the shocks 👍👍

    Swift lowering springs

    For those that want a mild drop and still feel oem like. I paired these with koni shocks and it feels a bit stiffer but nothing too harsh. Great ride for daily driving.

    Swift Sport Lowering Springs for 2008-2013 Infiniti G37x Sedan AWD

    Perfect drop

    Installation was straightforward and the springs gave me the perfect drop. Rides like stock on smooth roads but potholes are definitely more aggressive. Definitely the way to go if you want to get rid of the wheel gap on the awd G.
