About this item

  • Adds up to 25% more damping performance over original equipment shocks
  • Components and valving designed specifically for classic cars
  • High gas pressure design provides instant, extra control
  • monotube design outperforms all other standard shock absorbers
  • Unique, air-free, hydraulic unit eliminates performance fade


The KYB Gas-a-Just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-Just is available as an OE monotube replacement and as an OE twin-tube performance upgrade. The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness & control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

EM Corvair shock. Great on the front, poor on the rear. Use Clark's gas on the rear. Better control and the proper length to prevent too much droop.

The lower slotted brace is not wide enough to be captured by the bolts and the slots do not accept the 3/8” attaching bolts.

It's a shock, hard to mess that up. Fit my 79 Corvette, and changed the ride 100% over the old original ones.

Ride much better, easy install, just look online if you want to know how because instructions are "generic" and not for the actual product

Seems a good shock. Bushings, however, were very difficult to install without a method of compressing them, considering that while in place, the length of thread is not sufficient to get the nut started. I wound up cutting a small amount off the upper bushings in order to start the nuts. I take a star off due to this unexpected difficulty, as well as nothing in the instructions how to cope with it.LOL... in fact these were some of the worst instructions ever seen! Fortunately you really don't need much in the way of instructions to install shocks.
