Is the Gas-A-Just worth it over a cheap twin-tube shock?

For a stock-height truck used for towing or hauling, yes. The monotube design resists fade better under load than most budget twin-tube shocks, and at $66.44 at eBay as of November 4, 2026 it costs little more.

Will these fit my Silverado?

The KG54341 is listed for the rear of select GM trucks and SUVs, 4WD and RWD, at factory ride height. Check your model year and trim against KYB's fitment chart before ordering, since listings vary.

Do I need to buy two?

Yes. This is one shock absorber, and rear shocks should be replaced in pairs so damping stays even side to side.

One shock absorber and a dust cover. Mounting bolts are not included; the factory bolts are reused.

Are they adjustable or good for a lifted truck?

No. They are non-adjustable and built for factory ride height. A lifted truck needs a longer shock, such as KYB's Monomax line.

When is the price lowest?

Shock prices move little, but eBay listings and warehouse sales often undercut auto parts chains. The current $66.44 is already near the bottom of the range seen across the four stores.

Our take on the KYB Gas-A-Just Front Shock Absorber

The KYB Gas-A-Just is a monotube gas-charged replacement shock absorber, sold here in the KG54341 fitment for the rear of GM trucks and SUVs such as the Silverado. It is a non-adjustable, factory-height replacement aimed at restoring control rather than lifting or softening the ride. The monotube design gives quicker damping response than a worn twin-tube, which helps with nose dive, body roll and steering feel, especially when towing or hauling. At $66.44 at eBay as of November 4, 2026, it sits at the low end of its recent range across the four stores listing it new.

What reviewers say

Owners of older GM trucks commonly fit Gas-A-Just shocks as a cheap refresh and report tighter steering and less bounce over bumps. Some find the ride firmer than the worn units they replaced, which most see as the point.

Pros

Noticeable improvement in control and steering response
Holds up well when towing or carrying a load
Straightforward bolt-on install with basic tools

Cons

Firmer ride than stock on unladen trucks
Single-unit sale means buying two for the rear
