Monroe Magnum RV 555025 Suspension Shock Absorber

I'm in the process of installing the Monroe 555025 shock absorbers on my 11K GVWR toy hauler (2006 Fleetwood Gearbox 220FB). These shocks are replacing the Lippert 283271 shocks.The Lippert shocks were a replacement for the OEM shocks and were the exact same dimensions. The Monroe 555025 shock is longer in both compressed and extended dimensions than the Lippert shocks. See the first picture for an example of the compressed lengths of the Lippert shock on the right, Monroe 555021 on the left and the Monroe 555025 in the center. In that picture, note that both Monroe shocks are held in their compressed state with cable ties, while the Lippert shock has no restraint. Once compressed, the Lippert shock stayed that way unless I manually extended it. Yeah, it's that crappy. Essentially, it only provides resistance against extension. The Monroe shocks provide more resistance in BOTH directions than the Lippert shocks. I put the cable ties on the shocks. It made installing them much easier. The Lippert shocks use a fine thread on the stem, while the Monroe shocks use a coarse thread. After only two years on the trailer, the Lippert nuts were very difficult to remove. The end of the stem has two flat spots that made removal of the nut possible. I put a crescent wrench on the end of the stem to hold the shock, but a 1/4" open end wrench will also work. A 7mm open end wrench may work but isn't as good a fit.In picture #2, the Monroe 555025 shock is sitting in the trailer's shock mounting brackets. The bottom stem (not seen) has the mounting hardware (bushing and washer) on it. The trailer's frame is supported by jack stands and the trailer axles are allowed to relax on the suspension. There is enough room for this shock, when compressed. Picture #5 shows the same shock, still compressed, with the trailer suspension fully compressed on that axle. There is still a small amount of room for the shock within the brackets (the cable tie is between the shock and the mounting hardware, call it 1/2" of free space without the rubber bushings yet compressed).Picture #3 shows the shock installed with the trailer suspension at full extension. The shock is extended about 11.5". The maximum extension of the shock is 13.5", so there is plenty of travel left. Note the orientation of the shock. Don't install it upside down.Picture #4 shows the mounting hardware. The end of rubber bushing that is pointing up has to go into the trailer's shock mounting bracket. The other end of the bushing will not fit into the bracket. The metal washer will go against the shock or against the nut.The Lippert shock stems rusted badly and made removal difficult. I'm going to put something on the Monroe stems to keep them from rusting.Installation tip: Keep the shock compressed using cable ties. Place the shock into the shock brackets, still compressed. Using a jack, raise the suspension so the stem is well through both mounting bracket holes. Then cut the cable ties.

I put them on my fifth wheel rv trailer and so far so good. I have to say that they were a b*^@*h to install. My wife had to pry the springs down far enough to put the shocks through the bottom hole after I pushed as hard as I could to get them closed. I think this is the sign of a well built shock absorber. So yeah, I think they are good and of course, I will recommend them to the folks.

This product stinks because they say it's one thing and it's not so there is no value for the money

I replaced my OEM part # 177734 with these on my 2011 Mobile Suites 5th wheel. They are black not yellow which is no problem. That match all the dimensions of the OEM perfect. They went on very easy . Can be done with wheels still. I removed mine which gave more room for the job.

These work perfectly on our 1977 Holiday Rambler

I wanted to replace our old hydraulic shocks on our fifth wheel with new gas shocks. I should note that the comparison charts show that the replacement gas shock for our existing hydraulic shocks is part number 555001.As noted by other reviewers these 555025 shocks are rated for trailers with a GVWR over 10,000 lbs. Our fifth wheel is just over at 10,300 lbs, so based on other reviews I ordered them instead of the 555001.However, when they arrived it quickly became apparent that they are considerably longer than the existing shocks on our rig. Fully compressed these shocks are easily 1 1/2 to 2 " longer than the old ones fully compressed. Online advice suggests this might lead to damage if the shock were to compress fully where greater spring movement is still required.I have returned these shocks and ordered the 555001 version instead. It cost us $30 in return shipping PLUS a 10% restocking charge so it's worth a bit of time to figure out what you really need before you order.

American made shocks. Good price and good value!

These shocks made a huge improvement on the ride and towing on our 35 ft. 5th wheel camper. I had read reviews about these shocks being a little too long to fit in the shock mounting brackets. That was true. They only needed about 1/4 inch to fit into the bracket. That was no big problem. I used an 8 ton jack positioned close to the shock, on the frame, and lifted the frame about 1 inch and the shock went on easily. There is still plenty of travel room for the shock and the Monroe 555025 is much better than the factory shock. I definately recomend this product.
