Keep your suspension located and your ride controlled with the Delphi Suspension Control Arm TC6732, a direct-fit replacement for the rear lower forward position on the listed applications. This Delphi control arm connects the rear suspension to the chassis, locates the wheel through its travel, and carries an integrated ball joint that pivots as the suspension moves. It drops in for the 2008-2013 INFINITI G37, the 2009-2020 NISSAN 370Z, the 2023-2024 NISSAN Z, and more — see the Buyer's Guide tab for the full list of covered vehicles and engines.

  • OE-validated engineering: Delphi applies its OE steering and suspension expertise to the aftermarket, testing below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.
  • Verified integrity: each arm undergoes 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 is applied to each part for corrosion prevention and enhanced appearance.

Signs the original may need replacing include clunking on acceleration or over uneven roads, a loose or wandering rear end, and uneven tire wear. If a worn arm or ball joint is the cause, this replaces it.
