Parts for your 2016 Lexus Is-Coil springs

2016 Lexus IS coil springs — what they do and when to replace them

Based on the Lexus IS (XE30, 2013–2017) repair manual suspension section, the Toyota/Lexus Electronic Parts Catalogue, and Lexus New Car Features documentation, the 2016 Lexus IS range (including IS 200t/300, IS 300h and IS 350, with or without F Sport and AVS) runs coil springs on both axles: MacPherson strut with a coil spring up front and a multi‑link rear with separate coil springs. So coil springs are absolutely relevant to this model.

On the 2016 IS, the coil springs carry the vehicle’s weight, hold the ride height, and let the dampers (struts/shocks) control bounce. They’re tuned differently by variant — F Sport and AVS cars can have specific spring rates — but the job is the same: keep the sedan planted, comfy and predictable. When they sag or crack, handling and braking suffer and the ride can feel harsh or floaty.

There’s no fixed replacement interval for coil springs, but they should be inspected at each service. In Aussie and Kiwi conditions — coastal air, rough country roads, the odd pothole — it pays to keep an eye on surface corrosion and chipped paint, especially on the rear springs. If one corner sits lower, there’s a clunk over bumps, or the car bottoms out with passengers on board, it’s time to measure ride height and check the springs closely.

• Always replace in axle pairs to keep ride height and handling even.
• Match the exact spec to the VIN/trim (IS 200t/300/300h/350, F Sport, AVS), as spring rates vary.
• Renew related bits while you’re there: strut tops/bearings, rubber isolators, bump stops and dust boots.
• After fitting, torque fasteners at normal ride height and book a wheel alignment.
• Use a proper spring compressor — never heat or cut a spring.

If the shocks are tired, replacing dampers and springs together can be a smart move, restoring balance and saving on labour. Quality OEM or equivalent springs will keep the IS riding at the correct height, protect tyre wear, and make the most of its sharp chassis.

Regular rinsing underneath after beach trips and quick touch‑ups on any chipped coating will help fend off rust. With sensible loads and good roads, many IS coil springs last well past 150,000 km, but once they sag or crack, replacement is the only safe fix.

Do all 2016 Lexus IS models use coil springs?
Yes. Every 2016 IS uses coil springs front and rear. F Sport and AVS cars still use coil springs, the dampers change (adaptive), not the basic spring type. Spring rates can differ by engine, trim and equipment, so parts must be matched to the exact vehicle spec.

How long do coil springs last on a 2016 IS?
There’s no set expiry. Many last 150,000–250,000 km depending on roads, loads and climate. Inspect at every service for sagging, broken coils and corrosion, and replace at the first sign of damage or uneven ride height.

Can just one coil spring be replaced?
It’s strongly recommended to replace in axle pairs. Swapping only one spring can leave the car sitting unevenly and upset handling and braking balance. Pair replacement keeps things consistent left to right.
