Sharpen ride control on your classic Triumph with the KYB Gas-a-just Suspension Strut KG9125, a high-pressure monotube gas unit that installs in the front suspension of the 1967-1973 Triumph GT6, 1960-1970 Triumph Herald, and 1963-1979 Triumph Spitfire. Offered as an OE monotube replacement to help restore the vehicle's original capabilities, it uses two separate working chambers — an air-free hydraulic piston and valve area for responsiveness, and a high-pressure nitrogen area with a floating piston for a comfortable ride during normal driving with added performance on demand.

  • High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
  • Higher gas pressure: responds quickly to help improve steering response.
  • Up to 25% more damping: adds damping performance over original-equipment shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.
  • Triple chrome-plated piston rod: an ultra-smooth rod designed to reduce seal wear, since fluid leaking can be a cause of shock failure.

KYB notes that electronic safety systems depend on the suspension, brakes, and tires performing as intended; the Gas-a-just helps keep those systems working as designed. See the Buyer's Guide tab to confirm the fit for your Triumph.

Frequently Asked Questions

Which vehicles does the KG9125 fit?

It's cataloged for the front suspension of the 1967-1973 Triumph GT6, 1960-1970 Triumph Herald, and 1963-1979 Triumph Spitfire. Check the Buyer's Guide tab to confirm your exact vehicle.

What type of strut is this?

It's a KYB Gas-a-just high-pressure monotube gas strut with two working chambers: an air-free hydraulic piston and valve area, and a high-pressure nitrogen area with a floating piston.

How does the monotube design help?

The high-pressure monotube design separates the gas and oil for fade-free operation and instant response, while the higher gas pressure helps improve steering response.

What are signs this strut may need replacing?

Signs a strut may be worn include excessive bouncing, reduced ride control, uneven tire wear, or fluid leaking. Have the suspension inspected to confirm the cause before replacing.

Should I replace struts in pairs?

This listing is for one strut. Replacing both sides on the same axle together is a recommended best practice for balanced, even ride control.
