KYB Monomax Review
I have been running the same set of the blue and yellow Bilsteins for about 100,000 miles. That includes over 30,000 miles off road beating the heck out of them. Recently, I had a really hard slam in the rearend every time I hit even small bumps, like pulling out a driveway. I decided It was time for new shocks. Once removed, I found that the rear passenger shock had zero resistance for a few inches,then suddenly resistance started. All the other shocks were still working. I can't remember how hard they were to compress when I installed them, but they still had a good bit of resistance.
I went with the KYB Monomax this time because they are a little less money(paid 54 shipped for each one), have good reviews, and are said to be a firmer ride. I wanted the firmer ride because I carry a lot of extra weight. Between the camper shell, carpet kit, hi-lift, tow chain and so on I estimate there is around 300lbs in the bed every day.When I go off road there is an additional 100lbs to 300lbs, maybe more, depending how long I will be camping. Plus it is 4x4 and I run 32's in load range E.
First I did the rear, the lower bushing is a different design, seems to work fine though.
Up front I found that the top bushings are tiny, about half the diameter of the stock or Bilstein shock. This worries me a little. Furthermore, the stud on the top is a smaller diameter. The hardware included for the lower mount is cheap. As I recall the Bilstein hardware was also cheap and I replaced with a higher grade. I reused the old lower hardware as I could tell just from the weight they are higher grade.
Been driving them about a week now. No dirt yet. I find the ride is fine. I like the firmness in the rear end and it seems to take the big bumps much better. The little bumps on the highway are also better, but coming from old dead shocks its not a surprise. It has been so long I can't remember what the ride was like with fresh Bilsteins.
My dad has Bilsteins on a 2wd edge with the tow package and load range C tires. The shocks are not very old, and I ride in it often. The ride in his truck is ridiculously hard. (I have the same rear springs cuz of the payload package.) My truck is currently smoother riding than my dads because all the extra weight. I bet it would be smoother still if I ran load range c tires. (next time around I'm going to move to 15 inch rims because they make 32's and 33's in load range c)
In conclusion, if you have a 4wd and carry extra weight the monomax might be for you. If you have an empty bed, get the Bilsteins. If I was to do it again I would put the monomax in the rear and Bilsteains in the front. The small bushing and smaller diameter stud bother me. This is the downward travel limit up front, so I would think bigger and stronger is better.
I will keep this topic updated to see how they hold up.
