Is your Hyundai Sonata or Kia Optima riding rough, bouncing, or making clunking noises? This Detroit Axle 4-piece suspension kit is likely the solution. It includes everything you need: two complete front strut assemblies (with pre-assembled coil springs) and two rear shock absorbers. They're direct replacements for 2012-2014 Hyundai Sonata and 2012-2015 Kia Optima models with gas engines (check the detailed fitment notes for build dates and trim specifics). The big advantage is that the front struts come fully assembled – no need for a dangerous spring compressor or special tools, making DIY installation much safer and easier. They feature electrostatic coating for corrosion resistance and are engineered to restore ride height, stability, and handling. Detroit Axle backs them with a confident 10-year warranty. OE part numbers included: 182587, 182588, 4349243.
