KYB Excel-G Rear Shock Absorber

KYB Excel-G part number 344414 is a rear suspension shock absorber engineered to restore original ride control, stability, and handling. It is a direct OE-style replacement for select Ford F-150 and Lincoln Mark LT applications, with calibration focused on factory-like response rather than changing suspension character.

The Excel-G line is KYB’s Original Equipment for the Aftermarket offering, built on the same OE assembly lines and using OE-quality components. For drivers searching for a rear shock for a 2004-2008 Ford F-150 or 2006-2008 Lincoln Mark LT, 344414 provides a vehicle-specific replacement solution.

  • Nitrogen gas-charged twin-tube design
  • Triple-lip fluid seal helps reduce oil and gas leakage
  • Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
  • Strong strut body and bracket construction helps minimize flex and maintain alignment
  • Dust cover included
  • Part number 344414

Product Details

KYB Excel-G 344414 is built for rear suspension service where consistent damping matters. It measures 14.96 inches compressed, 25 inches extended, and 10.04 inches of stroke, with E2(12X38) upper and lower mounts. This shock absorber is calibrated to help restore the vehicle’s original suspension behavior, which is important for braking stability, lane-change response, and overall ride control. This part cross-references Monroe Shocks & Struts 911261 for the same application.

What This Shock Absorber Helps Address

  • Excessive rear-end bounce after bumps or dips
  • Reduced stability during braking or lane changes
  • Loose or unsettled handling from worn rear shocks
  • Uneven tire contact caused by weak damping control
  • Oil or gas leakage from an aging shock absorber

Installation Notes and Fitment

Fits 2004-2008 Ford F-150, rear. Fits 2006-2008 Lincoln Mark LT, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style, compressed length, and extended length before installation. For search relevance, this rear shock absorber is a common choice for Ford F-150 rear suspension repair and Lincoln Mark LT rear ride control service.
