Product Details

The KYB Excel-G line is engineered on KYB OE assembly lines using OE-quality components and calibration focused on restoring factory performance rather than changing it. Part number 335609 is an OEA-style replacement for the front left suspension strut on Ford Flex and Lincoln MKT models, with dimensions of 11.33 inches compressed length, 18.24 inches extended length, and 6.91 inches stroke length. The upper mount type is 14X2.00, and the unit includes an R-stop.

This part cross-references Monroe Shocks & Struts 72534 and 72727 for the same application.

What It Helps Address

  • Excessive bouncing after bumps
  • Loose or delayed steering response
  • Nose dive during braking
  • Body roll in turns and lane changes
  • Uneven tire contact caused by worn suspension damping

Installation Notes

Fits 2010-2012 Ford Flex, front left. Fits 2010-2012 Lincoln MKT, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify alignment after installation. For added protection, KYB recommends a strut boot, part number SB101, to help shield the strut from dirt, debris, and salt.
