My rear Monroe Shock Absorbers were leaking, and although replacing them is an easy job, I asked a shop to install new ones while doing other work with the Jeep up on a lift. My only request was that, in a world of "Good, Better, Best", I only wanted "Good".

To be honest, I don't know how to comprehend an advertised shocks' performance. They all say things like "Instant Response", "Monotube Muscle Only When Needed", "Seamless Extruded Mount" and the like, but I cannot find a specification that indicates how hard, soft, stiff, recommended load capability, compressive response with weight, or ANYTHING that I can relate to my application and what ride quality to expect. When I bought the now leaking Monroes, the parts guy brought out the appropriate version to fit the Jeep which were labeled "Heavy Duty". It seems everybody wants "Heavy Duty" of anything they buy. I asked about "Normal Duty" shocks for cost savings, he checked and said they were available but would have to be ordered... He had never sold a "Lower Duty" Monroe shock in his memory. He ordered, I got, and life was just fine.

So when I picked up and paid for the current work, the shop owner was quite proud of the shock selection they came up with. He actually put the Jeep on a lift to show me what they looked like, and they were beautiful! Red and Black, with a collapsible dirt sleeve, shiny and securely mounted, they made me wish that shocks were installed on the outside of the body for show. They were KYB MonoMax 565056, at $92.00 apiece. Although manufactured in Japan, I was happy with these, although, as I said, I didn't know any numbers to gauge how these would work and feel.

Being my daily driver, I regularly travel to work over some poorly maintained, patched and rough desert two-lane roads, and right away I felt very uncomfortable with the poor ride quality. The Jeep even sounded like it was taking a beating compared to my old Monroes. However, I was determined to "give them some time", because 1.) my memory and judgement of ride quality may not be forgiving enough, and 2.) I made the decision to pay for these shocks, and I'm going to MAKE them work for me! After awhile, however, I got down on my knees to look at these shocks just to make sure someone hadn't stolen them and replaced them with sections of 2x4's.

So I'm driving in town with two motorcycles behind me as I stopped at a red light. One of the motorcycles, a huge loud Harley ridden by a very big, bearded guy in a much decorated leather jack pulls up between me and the car in the adjacent lane, stops at my driver's side window and knocks on the glass. I was ready to hand him my billfold as he motioned for me to open my window (a slider on a steel half door).

"Hey, I just want you to know that your brake lights aren't working" The light turned green, we all took off and I headed home to troubleshoot my brake lights.

Bottom line, the connector on the brake pedal switch had come loose and was hanging free, no doubt in my mind that the higher vibrations from the rough roads and stiff shocks had played a roll. I also found some tie-wraps in the engine area that had slipped from their friction-fit installation points and were now loose, and the soft top frame had been vibrated loose at the adjusting points.

For me, a Jeep YJ is not a truck or load hauler. It is a lightweight, short wheelbase, maneuverable vehicle that is a bit unstable at interstate highway speeds. Concerning shocks, the key to me is light weight and light-duty versions are needed if you want to keep your teeth from coming loose.

So, I went on Ebay and found a pair of low-end Gabriel 81583 shocks that were being sold as part of an "out of business" garage auction. These were new shocks that were unsold at the time of the business closing, and I paid $30 for the pair. It took me about 40 minutes to swap these out. Easy Peasy.

I can describe the unmounted performance difference between these two versions of shocks in a most non-technical manner. I could exercise the cheap Gabriels in my hands, moving the shock over its entire motion range with dampening resistance in both directions. This characteristic made the Gabriels easy to line up and install the lower through- bolt. I could not move the KYB's by hand at all.

Driving the next day was a forgotten pleasure. A WORLD of difference. Much better ride, and far less SHOCKING!

With a smile, I threw the 3-week old $92.00 each KYB's into the trash barrel.
 
I did not replace the front shocks (yet) and will be looking for something soft. I suspect that the "low-end" Gabriels will have longevity issues, so I am not adverse to a different brand. Rancho certainly has market respect. When I buy shocks, even the RS5000X, I'm going to insist that I get one in my hands to work, now that I have a feel for it!
 
Wish I had gotten to you before ebay did. Rancho RS5000X shocks have a cult like following over on the TJ forum. They are likely awesome shocks for our YJ’s.
I don’t think they make a shock for the YJ do they? (In 5000x anyways). Last I looked I didn’t see anything that would work for us. On the other hand, I went with OME and they are fantastic on the YJ. So much better than RC, stock, and Bilstein. And then in the TJ world OME seems to be ok but not a crowd favorite.

Would be cool if Rancho did have a 5000x offering for the YJ though.

EDIT: should have looked before posting. They do have some offerings for the YJ. They are meant for shorter YJs but knowing how they’re all too long on the TJ, I bet they probably work out for most YJ suspensions. Interesting. Wish someone could post up how they are on the YJ.

Needed new shocks as my stock height 91' still has their original shocks. The process to upgrade suspension started with new tires - BFG KO2s. I am running with 30x9.5 which I have been happy with. However, the KO2s are heavier than the Michelin's A/T's that would just never wear out. Anyway, I began researching shocks for stock height 91 YJ. The list of decent choices were SKyjacker Black Max and Skyjacker M95 Performance, Rancho RS5000X and their RS7MT, Rough Country Premium N3, and the Bilstein B6 4600s. I wanted a more responsive and stable ride given our leaf springs. So I eliminated the twin tube designs like the SKyjacker Black Max and the Rancho RS5000x. The twin tubes may provide a more smoother and cush ride, but I wanted better performance - aka - a monotube. It came down to the Rancho RS7MT, Skyjacker M95, and the Bilstein B6 4600. I talked to a number of seasoned suspension vets and their was a consensus that Bilstein make a quality shock with Limited Lifetime Warranty. The issue for me was that I really didn't care for the light blue and yellow colors on the 4600's. So I continued to research... called the factories and talked to reps... In the end, all 3 remaining on my list appeared to be quality shocks. The deciding factor for me was that Bilstein uses vulcanized neoprene rubber bushings on their 4600's. I know a little bit about materials and shock absorption. And Marketing can continue to tell you that their polyurethane bushings are better than rubber bushings. Rubber bushings on shocks are FAR SUPERIOR than a polyurethane bushing from a shock or vibration absorption perspective. Polyurethane is much harder than rubber and this translate to a harder ride. Yes, polyurethane does do better with oil, but I never ever had an oil problem on my shocks. In fact, my original rubber bushings on my original OEM shock are still in great shape. I did hear some Jeepers talk about a harder ride with the Bilstein 5100's which I believe use a polyurethane bushing, but the 5100's are not available for stock height YJ's. I ordered the Bilstein 4600's from Kolak@aol.com at 480 998-3661. Nick will definitely hook you up and get you the best deal. I just installed front and backs and the 4600's are SWEET. What a HUGE difference from the old spongy shocks! And the 4600's do NOT produce a hard ride. The nitrogen shock is fast smoothing out the bumps in the road. And when you take a hard turn (which I couldn't do before), the Jeep rides nice and level. I drive performance race cars so I wanted something that provided a fairly smooth ride, but with great control - as much as you can on a YJ if you know what I mean. The Bilstein 4600's are on the money. And luckily on a stock heigh YJ, you really don't see the light blue and yellow colors on the Bilstein 4600 shock body so I was really concerned about nothing. I am 100% happy with these 4600's. You pay a bit more than a Rancho RS5000X, Monroe and KYB - Gas-A-Just, but you get what you pay for.

That’s a good review to hear. I am not on the road really yet but I swapped to stock suspension and kept the OMEs which are only about 0.5-1” longer than stock. They ride very cushy but sway a lot in turns. When I get done with the more important stuff, I am highly considering a set of Bilsteins for the stock application.

Do you still have track/sway bars?
 
Just wanted to include an install drawing since I couldn't find any usable instruction how to load the front shocks. In short, load them like the OEM does in terms of washers and bushings. It is how you would think to do it, that is, until read the Bilstein instructions that confuse something so simple.

Here is the drawing that I got directly from Engineering at Bilstein which is not included in any instruction or somewhere on the Bilstein website. Apparently it is secret.

Yes, Still have the sway bar set up. Everything is stock. You will not be disappointed with the 4600's. I'm glad that I spent some good time digging into this. I didn't want to spend good money on some pricey shocks and then just hate the ride. But the 4600's are great for the daily rider and if you want to do some off-road fun.

You can get Rancho RS9000X for about 85 dollars a piece on Rock Auto. These are similar to the 5000x but have adjustable dampening via a 4 position knob on the shock body. I ran these on an XJ about I dunno 20 years ago (shit time flies) and they rode very well but I could step up the dampening in the SOCAL desert so I could run the washes faster.

Let me know if you want to sell the Old Man Emu shocks when you swap. I've had them on a CJ5 and currently run them on my XJ and love them. Been wanting a set for the YJ but the Monroe OESpectrums I'm running now are ok as well and I hate replacing good parts just cause.

Can do. Still need some road time to decide if I’ll want to switch, but hopefully in a few more weeks. At least as long as it takes me to decide, you have something to continue to wear down in the meantime.
 
The 99 F250 4x4 i bought had new Monomax'es on it. As a former KYB Gas adjust fan I couldn't believe how these things were, yes I took them off and sold them. Might as well use 2x4's for shocks.

OH yeah I put the OESPectrum Monroes on when I overhauled the suspension for cost reasons. But have had my eye on OMEs again. No hurry.
