Delphi Suspension Trailing Arm P/N:TC4385
$226.99

Keep the rear suspension tracking true with the Delphi Suspension Trailing Arm TC4385, a rear left trailing arm that locates the rear axle and helps control wheel movement over the road. It installs as a direct-fit replacement for the 2011-2015 Hyundai Tucson and 2011-2016 Kia Sportage (see the Buyer's Guide tab for engine-level fitment). Worn or bent trailing arms can show up as clunking on acceleration or over bumps, uneven rear tire wear, or loose, wandering rear-end handling — if the original arm is the cause, this replaces it.

  • OE-focused engineering: Delphi applies its OE steering and suspension expertise to the aftermarket, validating parts across temperatures below -40°C to over 120°C and 720 hours of salt-spray exposure, with dimensional and material analysis for close OE-to-aftermarket compatibility.
  • Verified materials: control arms undergo 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Consistent build: robot welding delivers repeatable quality, and the ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.
