## Overview

The KYB 565121 MonoMax Gas Shock is a heavy-duty monotube shock absorber designed for trucks, delivering up to 40% more damping performance than standard shocks. Featuring a zinc-coated stainless steel piston ring and protective rubber boot, it offers fade-free, durable handling in tough conditions, making it ideal for heavy loads, towing, and off-road use.

## Description

Tough conditions demand tough truck shocks. The large bore KYB MonoMax provides the additional stability that heavier, more powerful or high center of gravity vehicles demand. The KYB MonoMax is a heavy duty monotube shock absorber that provides the most handling, control and durability of any KYB shock; and it’s just for trucks. The MonoMax’s tough design automatically adjusts to driving conditions with fade-free performance. The KYB MonoMax has an outstanding reputation for vehicles that do real work, go off-road, tow a trailer or haul heavy loads. It uses a work-ready, zinc-coated steel piston ring and includes an off-road dust boot.

Review: 2008 f350 - Just installed on my 2008 f350 powerstroke, crew cab short box... stock height. You don't realize how bad your shocks get, until you replace them. The truck rides like it should. Stiff, but comfortable. Absorbs small stuff beautifully, no more cab roll, no more nose dive when braking. Difficult to compress when installing, two people would have been easier. Couldn't decide between these or bilstein 5100. Extremely happy with this purchase so far... time will tell. This is a 8k pound truck. If you want it to ride like a Cadillac.... buy a Cadillac.
Review: Great shocks. - Just installed these on my 2015 super duty crew cab 4wd Platinum. Shocks have that OEM ride feeling. Truck rides and handles great.

### ⭐⭐⭐⭐⭐ 2008 f350
*by D***A on September 15, 2020*

Just installed on my 2008 f350 powerstroke, crew cab short box... stock height. You don't realize how bad your shocks get, until you replace them. The truck rides like it should.

### ⭐⭐⭐⭐⭐ Great shocks.
*by K***. on February 29, 2024*

Just installed these on my 2015 super duty crew cab 4wd Platinum. Shocks have that OEM ride feeling. Truck rides and handles great.

### ⭐⭐⭐ To small for good performance, updated 6-8-2024
*by K***E on September 14, 2023*

They are small diameter shocks, half the size of my Rear KYBs, or the RS9000 they replaced, haul a 28 ft bumper pull toy hauler with a utv rack in the bed with a KRX1000 on it, they work well for a bit when cold, but on long drives 6 hours plus they fade and loose their rebound, if you get out and feel the shock they are hot, in my opinion there isn’t enough oil volume to keep them from fading, the rear KYB does fine, as for the ride empty they are stiff but not horrible, it’s what I expected to get with KYBs description of them, if you do a lot of unloaded miles I would pass on them or get the RS9000, they are adjustable and I got over 150000 miles on them and on full stiff they were spot on for towing 6-8-2024 Already blew the seals out of the front shocks, and one rear, really wouldn't recommend them
