Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC7800
$140.99

Help keep steering precise and the wheel solidly located with the Delphi control arm — the TC7800 control arm and ball joint assembly. It drops in as a direct-fit front left lower replacement for the 2014-2020 Mazda 6 and 2013-2016 Mazda CX-5 (all engines), locating the wheel and letting it pivot and travel while the integrated ball joint allows steering movement.

  • Tested to OE extremes: validated below -40°C and above 120°C with 720 hours of salt-spray exposure, plus dimensional and material analysis for OE-matched fit.
  • 100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Micron-machined ball studs: the ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded, corrosion-protected: robot welding delivers consistent quality, and anti-corrosion protection is applied to each part.

Delphi applies its OE safety expertise to its aftermarket steering line, so this replacement is built to closely match the original part. If a worn control arm or ball joint is behind clunking over bumps, wandering steering, or uneven tire wear, this assembly replaces both components in one unit. Country of origin: Turkey.
