Question on front shocks on 345

It looks like the front shocks are original on 1988 345 that I recently purchased. My question is they have springs attached to the shock & I can't find a replacement like it. Does the spring come off and attach to a new shock or should I go with regular shocks with no spring. Thanks again! Moe

Someone has put "coil-over" shocks on your coach. I have not seen any of these on a motorhome. Do you have the air bags inside your main front springs? If your air bags are there and serviced with the proper 55 psi air pressure, there is no need for the coil-overs.
I replaced our shocks a few years ago. Bilstein makes some great shocks for our P-30 chassis.
You can go on line and find some great deals too.
Good luck, Rob

I know this is kind of an old thread but my '88 345 came with these shocks as well. They are factory installed along with the air helper springs in the main coils by the factory according to my owners manual and they are made by Bilstein. I have sent Bilstein an email along with pictures and part numbers to see if I can get replacements (they are not listed in their catalog so my hopes aren't high). I will update when I get more information. FYI the shocks have a special ring that holds the top aluminum casting in place so you can't simply remove the springs and the aluminum castings and install them on another set of shocks. Sure would be nice if you could though! Anyhow, I'll post Bilstein's reply as soon as I hear back from them. By the way, have you done anything with yours yet?

Whoops, I mixed up info read on the forum and other sites (and the fact that they are yellow and blue) with what I read in the owner's manual, the owners manual does state that the coil over shocks are factory installed, it does not say they are Bilstein. I should check my facts before I post instead of afterwards... Anyhow, once I quit looking for these in the Bilstein catalog I found them real fast, they are made by Trailmaster.

The shocks are available from Summit Racing part number TRL-630849 for $31.99 each, there was no picture but I am assuming at this price you only get the shocks and have to switch out the springs and aluminum castings from the old shocks onto the new ones. I ordered mine today and will update this thread when they arrive.

Shocks arrived the other day, they were bare shocks, didn't even include bushings. I wanted polyurethane so I had to order those as well. Got them today and installed them on my 345. They look great but I wish they had been yellow like the original ones. Boy the old ones were shot! Can't wait to see how much better the ol' girl rides now...

Here is the page from the owners manual mentioning the shocks and proper setting for the shocks. I don't know how many motorhomes they installed these on but they are factory added pieces.

Cool, I'm glad I was able to provide some information for my fellow forum members. Hopefully others will be able to find these shocks now when they need to replace their own and if you are still running the originals I imagine you need new ones... Mine had 45,000 miles on them and were trash but I imagine 23 years of service had more to do with that than the mileage.

On a side note the rep from Trail Master said I could also order the shocks through Rocky Mountain Suspension but I had already found and ordered them from Summit Racing Equipment when he emailed me and I have had nothing but positive experiences with Summit Racing and I have placed many orders with them over the past 25 years or so.

Springs on front shocks? I looked in my manual and the front shocks are listed as warrantied by Airstream and that is the only place it says anything about them. I replaced the shocks some years back and neither the old or the new have springs.
I have one air bag bad and was thinking of replacing the front coil springs with a higher load rated set. That is it I can find the thread that addressed the springs. Now I need shocks w/springs too. The hurt is on.

All because they used a standard spring with the P-30 chassis and did not opt for the heavy duty coil spring. for RV usage.

so in go the air bags and the Rancho Like coil over shocks by A.S. to amend the error. Kind of

Lets see: 1)bad air bag, 2)the wrong shocks, 3)springs that have 25 years of being over loaded and 4)the rubber stops are destroyed.
So someone tell me I'm wrong. Here goes: The air bags give 500-1000 pound more load, help stabilize, softens ride; coil spring shocks are no-load but help keep the rubber stops from being destroyed and help stabilize; OE spring are 3289 pound rated the bag 1000 pound for 4289 pounds which is setting on 3525 pound rated tires. I can buy a 4289 pound spring set ($161) and go ahead and replace the air bags ($80) and keep the wrong shocks at no extra cost.
Has anyone changed to the HD springs?
Does any of this make sense?
Should I or shouldn't I?

No one said no, so I did. One pair of HD springs, one pair of Firestone bag bags from TD Truck Springs. Not that I'm pushing TD Truck Springs, just want everyone to know how I died it I make a mistake while changing them. This maybe one of those: Get the hired help to do it

There is a thread about replacing the 'doughnut' suspension bags...actually sounds pretty simple if you have more mechanical ability than I do...Firestone makes them, and most competent mechanics can install them in a short amount of time...sometimes, mobile mechanics are more...well...versatile in repairs than fixed shops...if you find a good mechanic, hold onto them...worth their weight in gold...m
