Product Details

These Swift Sport lowering springs fit the 2013-2020 Lexus GS350 RWD/AWD.

The Swift Sport Lowering Springs for the 2013-2020 Lexus GS350 (GRL10) lower the GS350 for a more refined, sport-sedan stance while improving cornering composure. These GRL10 GS350 lowering springs provide an approximate 0.8" front and 0.8" rear drop, tuned to complement the stock Adaptive Variable Suspension. Made in Japan from Swift's proprietary H5S.TW material, these GS350 springs reduce body roll and sharpen steering response, giving the GS the more engaging driving dynamics that its powerful V6 and rear-drive platform are capable of delivering.

    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.
