OE-Style Rear Lower Forward Control Arm

Delphi TC8365 is a suspension control arm for the rear lower forward position on select Mazda 3 and Mazda 3 Sport models. Built as a standard replacement with a steel body, painted finish, and rubber bushings, it supports precise rear suspension geometry for everyday driving.

Delphi applies OE-focused dimensional and material analysis to help ensure proper part-to-vehicle matching. This Delphi TC8365 control arm is engineered for the rear lower forward location on 2014-2017 Mazda 3 and 2014 Mazda 3 Sport applications.

Detailed Product Information

Delphi TC8365 is built for the rear lower forward suspension position and is listed for 2014-2017 Mazda 3 and 2014 Mazda 3 Sport. The arm uses casting/forged construction with a steel control arm material, black bushing color, and a painted finish. Dimensions include a 14.63 in overall length, 57.92 mm width, 75.0 mm height, and 327.0 mm distance between bushings.

Delphi’s OE engineering approach includes temperature and corrosion testing, along with dimensional and material analysis to support fit and function in aftermarket service. If you are replacing a worn rear lower forward control arm on a Mazda 3, TC8365 provides a direct replacement format for the listed applications. This part cross-references MOOG Chassis Products RK643611 for the same application.

What This Control Arm Helps Address

  • Rear suspension looseness or instability
  • Clunking or knocking from a worn control arm assembly
  • Uneven tire wear caused by suspension geometry wear
  • Excessive rear-end movement over bumps
  • Failed rubber bushings in the rear lower forward position

Installation Notes

Install Delphi TC8365 only in the rear lower forward position specified for the vehicle. Verify bushing orientation, mounting-hole spacing, and overall arm length before installation. Because mounting hardware is not included, reuse or replace fasteners as required by the vehicle service procedure. A professional alignment is recommended after suspension component replacement.

Quality Assurance

Delphi uses OE-based testing and material validation for its steering and suspension components, including exposure to extreme temperatures and extended salt-spray corrosion testing. That engineering focus supports consistent replacement quality for Mazda 3 and Mazda 3 Sport service applications.
