Locate the rear wheel and control its fore-and-aft movement with the Delphi Trailing Arm TC6284, a rear left unit that installs as a direct-fit replacement for the 1999-2003 Mazda Protege and 2002-2003 Mazda Protege5. See the Buyer's Guide tab for engine-level fitment. It's built on Delphi's OE safety technology, fitted to millions of vehicles worldwide and carried into their aftermarket portfolio.

  • Tested to the extreme: validated below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for close compatibility between the OE and aftermarket part.
  • 100% inspected: every arm undergoes complete crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Robot-welded: assembled with robotic welding for consistent performance and quality.
  • Precision ball studs: ball studs machined to micron tolerances for durable, smooth joint operation.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

If a worn trailing arm on your Protege is the source of rear-end clunking or instability, this replaces it and helps restore proper wheel location.

Frequently Asked Questions

What does a suspension trailing arm do?

It links the rear wheel to the chassis and controls its fore-and-aft movement, helping keep the rear wheel located and the suspension geometry in place.

Which vehicles does the TC6284 fit?

It's a direct-fit replacement for the 1999-2003 Mazda Protege and 2002-2003 Mazda Protege5. Check the Buyer's Guide tab for engine-level fitment for your vehicle.

Is this a front or rear part, and which side?

This is the rear left trailing arm. Confirm the position matches the arm you're replacing before ordering.

What are signs this trailing arm may need replacing?

Clunking over bumps, rear-end instability, or uneven rear tire wear can be signs of a worn trailing arm. Have the cause diagnosed, since other suspension parts can produce similar symptoms.

How is the TC6284 protected against corrosion?

Delphi applies anti-corrosion protection to each part for corrosion prevention and enhanced appearance, and validates it through 720 hours of salt spray testing.
