Opinions - Morryde x-factor cross brace

[Hammerboy]

My next project on our 5er this spring is to install the Morryde upgraded wet bolts and shackles. While I am at it I am thinking of installing the Morryde x-factor cross brace at least on the center hanger. (mostly so I can sleep better at night :))

So anyway here is some basic info on our rig.

- 4" long spring hangers - not as long as some out there.
- Dexter EZ flex equalizer
- 10" cross members/beams between the 10" main I beams withing 8" of the center and rear spring hangers and within 18" of the front hangers.
- Dry wieght of #9100 and maybe 10K loaded (need to cat scale it yet)
- Total length of 5er aprox. 32' pin to bumper.
- Lippert frame :E

So, I am asking for the wiser ones than me for your opinion. Don't worry about putting them on, just the center one is fine, or do all three?

Thanks everybody

For some reason, all the pics are now showing on my older post.

TT Spring Hanger Stiffening (Long, lots of pics)

I may be a little late to the party, but I'll add my comments.

If there is a chance you can post pictures of your front, rear axle and center axle hangers, we can see if you have the "issue".

So what is the "issue"?

Back in the early year 2,000's, campers started getting more I beam style frames across the industry. As time went on, cracks started forming in the web of the I beam just above the hangers from the hangers flexing in turns. The longer the hangers, the worse this was. The more miles towed, the worse it was.

Soon a pattern to the cracks was evident. There was lack of rigid support between lower flange of the I beam and the web. The lower flange would flex and over time crack the web.

These I shape manufactured housing beams used for campers have very weak lower flanges. Some RV manufacturers addressed the problem by adding support to the lower flange. This halted the web flexing and then no more cracks.

This made it to be a big enough problem that there is even a Lippert how to fix it sheet on the NTHSA website. Yet, we still have campers being built today with the same issue. No lower flange support on long hanger suspension.

I learned about this in the later 2,000's and I made my own cross member supports to go between all 3 hanger sets. Guys who go off road, like toy haulers knew of the issue as their off road travel to camp aggravated the problem worse then the asphalt road folks. The toy haulers guys where welding in channel iron stiffeners on brand new campers to ward off the issue.

Picking up from the toy hauler group, I reinforced the hanger itself and the frame. My camper, while a travel trailer in place of a 5'er, has the heavier 10" I shape frame with 5" long hangers and loaded weighs just under 10,000# scaled. My issue was hanger bending when turning and staying bent. I never cracked the frame as the reinforcing tubes and the added flange support stopped it.

I even have a picture filled post here on RV.net on this, but for some reason all the pictures are not viewing on that older thread.

Bottom line: If you plan to keep your camper a good while, adding hanger reinforcement at all 3 locations is a worthwhile upgrade.

Since I cannot see yours, I do not know what you have.

Hope this helps

This is the correct route.

Check this video on the SRE/4000 system. They also boxed in the spring hangers.

JMO but I'd do all 3. During a tire change my dealer's service managed discovered the trailer's main frame was starting to crack on both sides, just aft of the rear tire. :E After arguing for some time with Coachmen and Lippert over who would cover the cost of repair the dealer welded in reinforcing plates around the affected areas AND installed 3 cross member supports. I don't know whether these were from a Morryde kit or pieces the welder created himself but they certainly did strengthen overall frame rigidity and eliminated any further concern that the frame might rack in any way in the future. :B

The cross bracing is not about what you feel, it is to help prevent the racking of the frame. As you round a curve the entire weight, much of it very high, is pushing against the spring hangers flexing the frame and possibly causing weld and material cracks. The cross bracing will reduce that damage considerably. I had failures where the few pathetic frame cross members were punching thru the main rails.

Last summer I installed the SRE4000 and the one X-Factor cross brace that comes with it in the center. I really can’t tell if the X-Factor adds much at all. In theory it can’t hurt. I might be tempted in your situation to do the center one and see what you feel if the two additional ones are needed.

Just my opinion.
If you are going to keep this trailer for a long time or travel a lot of miles go all in.

Heavy duty shackles and wet bolts.
Sre4000 (it comes with a x factor)
X factor on front and back.

At a minimum I would do heavy duty shackles and wet bolts and 3 x factors

Just an FYI: IF you would decide to also add the SRE-4000 equalizer, Morryde will void the warranty on it if you DO NOT add the X-Factor to the center hanger. So I guess the center hanger is the weakest link.
