Thinking about changing out my Monroe shocks for KYB Gas A Just.
Car is mainly a cruiser, no complaints with the Monroe’s, other than being 15 yrs old.

70 Challenger, 340, 0.92 BB torsion bars.

hi ,

save your money , kyb valving not mopar savy .

They feel good on my '66 Charger. 4150 lbs. with driver. No complaints here.

Got them on the front of my Savoy and I really like them. I have the Rancho adjustables on the rear set at #2 for street and #8 for the strip and gives me 1.51 60" times on M/T E/T Streets.

Do a real search here, I hate beating dead animals

I tried them on the 4 corners of my 65 Barracuda years ago. Worked well on the front with A body 383 T-bars but on the rear with SS springs I did not like them as much.

Now on my 84 Shelby they were great. And on the wifes Buick Regal too.

They are a horrible shock on a performance tuned suspension but they might work okay with the 0.92 bars. If you have low performance tires then a low performance shock will be okay since you'll never really notice the difference.

If you have performance tires and are looking for a performance shock then go with Bilstein, Fox or Koni.

Looks like mixed reviews, some like, others don’t.
Is harshness the main complaint?

KYB’s $100, Bilstein’s $500, are they 5 times better?

Or just get another set of Monroe’s?

Just get some more Monroe's.

Have used KYBs on my Mopars for years. They work great with stock suspensions. However I’ve found that when you start stepping up to bigger sway bars, torsion bars they don’t seem to keep up. I’m a big Firmfeel fan. The last several resto I’ve done I’ve done full tilt. The Bilstiens are the go to shock for me.

KYBs use digressive valving with high pressure nitrogen. This means they provide a large amount of resistance very early in travel that tops out and can't provide additional resistance as it reaches the end of travel. So this means on the small, rapid, high frequency bumps encountered on average roads, they can feel harsh, especially in cars of lesser weight, and on really large dips and constant, long, arcing turns they may feel good .

Yes, their valving turns the shock into a rock with high spring rates. The OP has 0.92 bars which are firm for factory settings but fairly soft by modern standards. The KYB shocks might work with those bars. With anything larger than a 1.00 inch bar the KYB shocks will make your car ride like an empty dump truck.

They are 5 times better if your car gets driven hard. They aren't if the car just goes to Bob's Big Boy once a month for ice cream. I put Bilsteins on my Dodge Ram truck when it was brand new since I thought the factory shocks were terrible. The truck only had a few hundred miles on it when I changed shocks. I bet 99% of the people who bought brand new Dodge Ram trucks kept the factory shocks on them. I've put multiple sets of shocks on my Coronet over the last few years just because I was looking for a certain feel. I finally decided that Koni shocks were the best of the best. There is no universal answer, it all just depends on what you're trying to accomplish. I will say that if you have never driven a car with good shocks then you don't know what you don't know.

I've got KYB on my E-body and it will be a one time deal. They are cheap enough, but if you value a quality ride, not worth the savings.

I've run Kyb's for years and have installed a couple hundred sets on customers cars. Only had one that thought they were to stiff.
Monroe's are absolute junk in my experience

They were okay on my Diplomat Police car. A bit firm but I didn't have a problem with them.

Make sure they are fully compressed and tied that way from the seller because what a B*tch they were to compress all the way to get on the front of my Diplomat!!!

Kyb too stiff..love my old school monroes..nice smooth ride

Amazing... 10 years ago everybody adviced KYBs Gas-A-Just ( or Just-A-shocks, whatever they call now ), now everybody claims they are too stiff.

However, everybody advices to get rid of the isolation systems on 73 and lates B bodies for a solid assembly ( but we are claiming about KYB Gas-A-Just stiffness )

we are becoming old LOL


10 years ago we had also the Edelbrock IAS shocks, but they were gone while ago

My first bad experience with KYB occurred in the late 80s with a 4x4 lift kit. Never recommended them since. I'm sure some folks are happy with them but typically what I've seen is their high pressure and digressive valving makes them an inexpensive crutch for inadequate spring rates.

I think as consumers we are getting more educated about suspensions now than many were ten years ago. 20 years ago I was selling suspension upgrades through my company and we sold 3x as many engine parts as we did suspension parts. Now there are entire companies out there dedicated to it. There just wasn't the broad demand for performance suspension systems then that there is today.

Commuter cars of today have more spring rate than muscle cars ever did in their day. It isn't that we are getting old and wanting soft rides, its that we want performance and control that provides a level of comfort and confidence, and its entirely possible to get that. But you won't get it for $50 a pair in shock technology from a company that has not updated their product in several decades.

I think we all have our own definitions of ride quality obviously, firm, stiff, solid, harsh, dump truck, soft, etc.
Harsh would be mine for the KYB's, and never again.
