Torsion axles or spring??

I just sold my 7x14 +5' V Rance Renegade trailer and am looking to upgrade to something around a 7x22. I will be using this for dual purpose, goose and duck hunting Sept through Dec and then snowmobiling after that. I have been looking for something tall enough to get a Can Am Commander into but am having trouble finding something tall enough. Also I am seeing a lot of trailers out there with spring axles now. My Rance had Dexter Torsion with brakes on all 4 and ez-lube hubs and I loved them. Anyone want to chime in on pros and cons of spring vs torsion and maybe point me toward something??

It seems (I don't want to offend anyone on here) that the spring axle trailers are cheaper than the torsion axle ones, thoughts???

I don't think it matters. Torsions have less nuts/bolts/parts to break & rust, and they look cleaner, which is nice. Spring axles are actually better if you don't run your trailer perfectly level....because the spring configuration being "coupled" distributes some weight from one axle to the other when things are unbalanced. Torsion has independent axles and can't do this. So where this could become a problem if for example you're running a torsion with nose down (improper hitch height), you might be overloading the front tires and underloading the rears. That's when people start popping tires or seeing uneven wear, and begin blaming everything but the actual cause (junk chinese tires/inflation/overloading/spring type/axle alignment)...when the actual cause of the problem is nothing more than the drop height of their hitch.

So spring axles can be more forgiving to poor towing setups, and they can be a bit more likely to have rust problems with age. Torsions are cleaner looking and have less parts, but are more sensitive to being run out of level.

They both hold your trailer up and absorb bumps.

People seem to favor torsions as being "better" for some reason, and I've never understood why. But if that's how many in the public feels, then it could be a benefit to you to have torsions at resale time. I know when I go to sell my trailer, I will tout the "benefits" of it having torsions to help my sale price...even though I know it makes no difference. Just happens to be how R&R equips theirs, and that happens to be the brand I purchased.

But for me, it was not an important shopping decision when comparing trailers.

I'll just add that if you ever have to replace an axle the leaf spring axle will be much cheaper than the torsion spring axle. The only real wear part on the leaf spring suspension that needs periodic replacement is the spring eye bushings. They are cheap and easy to replace though and should last for many years before needing attention.

To solve your problem with finding a trailer tall enough to handle your Can Am Commander....order your trailer with specific trailer height requirements. Typical inline trailer heighth is 6'....so order one that is 6' 6" or even 7'.

My 2014 Neo 7x28 has an interior heighth of 7 ft. Was tired of hitting my head when I walked around the inside my previous inline trailer. Plus like you I wanted more heighth if I decided to buy an off road vehicle that would require the trailer interior to be taller than 6 ft.

if you have the green...they'll build the machine!

The problem is getting it through the rear door opening. Once you clear the opening and door spring you are usually O.K.

I have a RnR trailer and my Maverick will not clear the door opening. I have 78 inches of clearance inside. Door opening and spring clearance is 74 inches. Maverick height is 76 inches.

Let air out of tires........

The suspension geometry suggest that the spring suspension should have a higher roll-center and therefore be less tippy around corners, but I've never noticed any difference.

Torsion axles, the way they work have some naturally built in dampening, but if that was a big concern, they'd put shocks on leaf spring trailers.

Someone said spring is better if you keep your sleds in it year round compared to torsion. Is this true ???????

Shocks and brackets cost money. Everyone buys snowmobile trailers by price. So adding them from the factory and increasing cost to build would be snowmobile trailer sale suicide. Since my snowmobile has never complained about hitting a bump, I've decided my trailer doesn't need them, and I don't want to pay for them. But if anyone has a snowmobile that has been complaining about the uncomfortable trailer ride, you can just buy one of the many trailer shock kits available, install, and make them all comfy:

There's even a cool comparison video showing how nice they work:

The real point is to eliminate the oscillation.

I wish I would have gotten a video of that guy driving his SUV pulling a camper trailer out of the Arctic Man parking area. By the end of the week long event, the road is always horrible and bounces a lot. Just about everyone with sense stops shortly after getting on the highway and checks tie downs and straps.

Anyway, that camper trailer was bouncing up and down so much that anything inside it didn't have any chance of being in the right spot when they got home. It was bouncing so much that the back of the SUV was being lifted up. My son said it looked like one of those cartoon trains that bounce side to side and up and down. I don't think either of us stopped laughing until we got to the highway.

I understand...my "snowmobile comfort" comments were sarcasm obviously. But my underlying point is that for the few people who would find benefit from having shocks on a trailer (like the people who regularly travel the types of roads you're referencing), aftermarket kits are readily available for purchase and installation. The rest of us IMO simply don't need them, nor do we want their the added cost. So directly answering your first question...that's why they don't put shocks on trailers. I don't disagree that some might benefit from them.
