KYB Suspension Shock Absorber P/N:KG5517
$63.99

Firm up worn rear damping with the KYB shock absorber KG5517, a Gas-a-just high-pressure monotube gas shock for cars and trucks that installs in the REAR position. It's a direct-fit replacement for classics and work vehicles like the 1964-1973 Ford Mustang, 1962-1970 Ford Fairlane, 1960-1970 Ford Falcon, 1985-1999 Chevrolet P30, 1961-1973 Volvo 1800 and 1969-1978 Saab 99 — see the Buyer's Guide tab for the full list of 33 applications.

  • High-pressure monotube design: keeps the nitrogen gas and oil separated for fade-free operation and instant response, and won't fade from aeration like a traditional twin-tube.
  • Two working chambers: an air-free hydraulic piston and valve area for control, plus a high-pressure nitrogen area with a floating piston for a comfortable ride during normal driving.
  • Triple chrome-plated piston rod: ultra-smooth to reduce seal wear, since fluid leaking can be a cause of shock failure.
  • Vehicle-specific valving: components and valving designed specifically for your vehicle; KYB states it adds up to 25% more damping over OE, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure of this KYB gas shock absorber responds quickly to help improve steering response and helps keep electronic safety systems performing as designed.

Frequently Asked Questions

Is the KYB shock absorber KG5517 a front or rear unit?

It is cataloged for the REAR position on the listed applications. Check the Buyer's Guide tab to confirm the fit for your specific vehicle.

What makes the Gas-a-just monotube different from a twin-tube shock?

Its high-pressure monotube design keeps the nitrogen gas and oil separated in two working chambers for fade-free operation and instant response, rather than mixing in a single twin-tube body.

Will this KYB gas shock absorber fit a 1964-1973 Ford Mustang?

Yes, the 1964-1973 Ford Mustang is on the fitment list for the rear position. Always verify your year and model against the Buyer's Guide tab before ordering.

Does the KYB shock absorber price cover one shock or a pair?

This listing is for one KG5517 shock absorber. Replacing both rear shocks together as a matched pair is recommended for even, balanced ride control.

What are common signs a rear shock may need replacing?

Excessive bouncing after bumps, a floaty or unsettled ride, uneven tire wear, or visible fluid leaking from the shock body. Diagnose the cause before replacing.
