KYB Gas-a-just Rear Shock for Ford Excursion

The KYB Gas-a-just KG54329 is a monotube rear shock absorber built to restore OE-style control on 2000-2005 Ford Excursion models. It uses separate gas and hydraulic working chambers for quick response, stable damping, and consistent ride quality during everyday driving and heavier-duty use.

Key Features

  • Monotube design with separate gas and oil chambers for fade-resistant operation and fast response
  • Up to 25% more damping performance than original equipment shocks
  • Valving and components engineered for Ford Excursion rear suspension applications
  • Higher gas pressure improves steering response and suspension control
  • Triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Dust cover included

Product Details

Gas-a-just is KYB’s monotube shock line for vehicles that work, tow, or run larger, heavier tires and wheels. The KG54329 uses a high-pressure nitrogen gas charge with a floating piston to keep the hydraulic fluid separated, which helps maintain consistent damping under load. For Ford Excursion owners, this rear shock is a direct-fit suspension service part for restoring control, ride stability, and suspension response. Part number KG54329 is also referenced by Monroe Shocks & Struts 911174 and Gabriel 77607 for the same application.

Common Problems This Shock Can Address

  • Excessive rear bounce after bumps or dips
  • Reduced control when towing or carrying heavier loads
  • Soft or delayed suspension response
  • Fluid leakage from worn shock seals
  • Uneven ride quality from tired rear dampers

Installation Notes

Fits 2000-2005 Ford Excursion, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style and dimensions before installation: compressed length 15.47 in., extended length 25.35 in., stroke length 9.88 in. Upper mount type E3(61.6X87X30) and lower mount type E2(12X38) are listed for this application.

Quality Assurance

KYB designs Gas-a-just shocks as OE monotube replacements to help restore original suspension capability. The KG54329 is built with a high-pressure monotube layout and a chrome piston rod to support consistent damping and reduced seal wear in demanding rear suspension service.
