Product Details

The KYB MonoMax 565121 is a heavy-duty monotube gas shock absorber engineered for trucks, SUVs, and vehicles that demand superior handling under tough conditions. Designed specifically for heavier vehicles, high center of gravity applications, and demanding use cases, the MonoMax delivers exceptional stability, control, and fade-free performance.

Key Features:

  • Large bore monotube design for maximum heat dissipation and consistent performance
  • High-pressure gas charge provides immediate response and prevents cavitation
  • Automatically adjusts to changing road and load conditions
  • Work-ready zinc-coated steel piston ring for enhanced durability
  • Includes protective off-road dust boot to shield against debris and contaminants
  • Ideal for vehicles that tow, haul heavy loads, or go off-road

The MonoMax represents KYB's highest level of handling, control, and durability in their truck shock absorber lineup. Its monotube construction keeps the gas and oil separated, ensuring consistent damping performance even under extreme conditions where traditional twin-tube shocks would fade. Whether you're hauling equipment, towing a trailer, or navigating rough terrain, the KYB MonoMax 565121 provides the stability and control your vehicle needs.

I got what I ordered. I usually don't leave comments and don't like that you are making me.

No comment

They had what I needed, it was priced right and it shipped on time.

The product was as expected and on time.

Awesome took almost no time to get what ordered.

Everything as advertised

Moved through site with ease, found what I was looking for quickly. In and out!

I was under the impression by 24hr shipping that i would get it the next day. But, turns out that it "leaves" with in 24 hrs and can take 3-10 days to arrive. It's a little misleading, but I did receive it in 3 days, so I'm "ok" with the delivery time (that is why i gave it 4 stars). 10 days would have been an issue.

Quick and easy.

great transaction, very fast shipping

VERY GOOD

It was very easy to order my husbands part.

Good so far...

Easy to navigate

Great communication, Great prices! They beat all the competitors hands down on price for my cold air intake order #18986. Quick shipping and they are now in my favorites for places to look for automobile needs. The only thing I would like to see them change is the speed of their website.

Order an item a day ago and the next day its shipped! Had a question and customer service was there when you needed it!

Ordered some fluid coolers for a project, great price, easy website, FAST shipping!

So far so good

Very good experiance with seller. I order husky floor liners for my '09 honda accord and they where 30-40% less than any other online store. Item arrive quickly, And couldn't be more happier with transaction. Defenetly i will look forward for my next car needs to deal with Autoplicity. 5 Star defenetly...............
