The NAPA/Monroe shocks actually look like the lippert light duty shocks. I'm sure a passenger car shock that has to dampen maybe 1000lb per corner won't be enough to dampen closer to SEVERAL thousand pounds per corner.

So, I received my 4 new shocks from Lippert on Wed. and got them on this morning. The new shocks are NOT exactly like the old ones. Old= 7.5" compressed, 12" extended. New=8.5" compressed, 13.5" extended. The installed length is 10". I hope they don't bottom when I hit a bump. The part number on the new is the same as the old. New shocks are gas charged, the old have no gas but it probably leaked out as they wore out. The new shocks are not nearly as stiff as I think they need to be and the dampening seems to be approximately 45% compression and 65% extension=a little stiffer when extending. I will continue looking for something I think is more suitable.

Installing the new shocks was very easy, I have the 6 way leveling system and just broke the lugs loose then ran it up so I could remove all the tires. A 9/16 deep socket is all that's needed once the threaded studs are cleaned off. I also installed urethane end grommets instead of the stock rubber grommets, this will take out the give the rubber has before the shocks start to actually dampen the movement so they will be more effective. BTW Lippert only included hardware for 2 shocks, not for 4 so I just reused the nuts and washers from 2 of the old shocks.

I also lubed the spring pivots while the tires were off-it's much easier that way. The first time I lubed the spring pivots, 2 years ago I found ALL the grease fittings loose-not impressed with Lippert QC. I lubed the bearings on my Dexter ez-lube axles, I LOVE those gun drilled axles. I checked the air pressure in the tires and torqued all the wheels. We are all ready to hit the road again tomorrow morning!

You can always go to some expensive racing shocks that have adjustable valving. We used Carrerra at about $150 ea 20 yrs ago. They are aluminum body shocks and are adjustable to just about anything you want.

I thought of that but these are straight studs on each end, if they had eyes it would be easy.

BTW the pn on the shock is 177734 which I can't get to come up for anything on the internet.

That's certainly do-able. I can fabricate just about anything. I've got a 1000 mile trip starting tomorrow to test it out with these shocks.

We have a 2013 3400 and in May we were traveling down I5 from Oregon when we ended up with a blow out. Ended up with damage on the slide and under carriage. We aren't close to a good authorized dealer for repair so have ended up with a RV Repair shop. After this happened and taking the trailer to our local tire shop he discovered that the shocks have been rubbing on the inside of our door side tires. After looking at the situation it looked like the axles either had shifted or something else. We have it at the repair shop fixing the tire blowout damage and then dealing with the axle or come to find out shock issue. After contacting Prime Time they said that this is a shock issue. They had put these shocks on some of their trailers before discovering there were issues. We/They are very lucky that this was discovered. This is a major safety issue. We could of easily had 2 tires blow out at once with the rubber it was taking out of the tires. I am hoping they take care of replacing the shocks along with buying us all new tires. Considering what a safety issue this is why can't Prime Time contact the owners with a recall notice.

That sucks, I have plenty of clearance on my 3500. They COULD contact most of the owners (some, like me are not where we were when we bought the trailer) but it would cost a ton and it's all about the $$ like any business. They have been very good to me with issues, hopefully they will be as good to you.
