Detailed Description

This StrongArm trunk lid lift support, part number 6786, is engineered for the rear compartment on 2010-2013 Mazda 3 models. As a pressurized lift support, it helps maintain trunk lid position while reducing the effort needed to raise and lower the lid. The specific-fit design and matched dimensions support proper alignment and consistent operation for the Mazda 3 trunk lid application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Trunk lid that will not stay open
  • Weak or slow trunk lid lift action
  • Uneven or inconsistent trunk lid support
  • Excessive effort needed to open the rear compartment
  • Worn gas strut performance on a Mazda 3 trunk lid

Installation Notes and Tips

Verify fitment by year before installation: Fits 2010-2013 Mazda 3, N/A. Inspect the mounting points and ball socket ends for wear before replacing the support. For proper operation and balanced support, replace lift supports in pairs when servicing the trunk lid system.

Quality Assurance
