How to Pick Out the Correct MORryde Equalizer Kit for a 2022 Arctic Fox model 25W

Question

Question:

Hi there, I have a 2022 Arctic Fox model 25W, tandem 5000lb axles6lug with 225/75R15 tires. I measured the axles center to center at 35, the stock equalizer is a Dexter component, it measures 4inch in height from center of hanger bolt to center of shackle bolt, and 6inch in width from center of shackle bolt to center of shackle bolt. When looking up equalizer upgrade parts for a 35inch wheelbase, most equalizer upgrade components are 8inch center to center for the shackle bolts and 4inch in height for the hanger bolt. However, when looking up parts for 33inch wheelbase, those upgrade components more closely match the dimensions of the factory dexter equalizer, 6inch wide but only 3inch in height in terms of center to center of bolt holes. Do I go with parts for the 35inch wheelbase, or parts that more closely match the factory equalizer, which in this case are parts for a 33inch wheelbase? MR89DR??? Thanks in advance.

Hey Frank, when you go to choose the correct equalizer kit you will want to match the equalizers not the wheelbase. So since you mentioned the 33" wheelbase # MR89DR version most closely fits your current equalizers, that's the one you're going to want to use.

If you have more questions or need help with anything else, feel free to let me know below and I'd be happy to help!

Hello I had a local shop purchased from e trailer the Morryde All Treck 4000. Did the 33” wheel base one since it closely matched the closest my existing Dexter 13-10 equalizer even though my wheel space when started was 35” My question when he went to install with the original Leaf springs witch are 26” long eye to eye. The issue he ran into the leaf springs with the weight on it bottomed out against the new All Treck 4000. To resolve this he install new leaf springs 25-1/4 eye to eye. And it looks ok but is this the correct fix do I need to be concerned with anything happening in the future or a safety issue Thank you in advance Dan

@Dan You chose the correct ALLTREK 4000 so you're definitely on the right track. There could be a little nuance with the fitment like if the shackle straps were swapped around as well. This could cause just enough of a difference in the geometry that you're seeing the issues you mentioned. As long as the leaf springs are rated properly and they are in the right orientation you'll be good to go! Feel free to shoot me some photos in a reply to the email you received from me for this comment, and I can take a look as well if that would make you feel a little more comfortable.

@Dan I got them - thanks! In the photos you sent, you want both sides of the equalizer to look the same in regard to where the leaf springs are located and how they sit. I can't quite tell if it's the angle or not, but are the shackle straps at slightly different angles? Did your trailer shop replace all of the leaf springs, or just one set of them?

Hi Greg; I wish there was a way for me to know the correct parts for that 2023 Coachmen Catalina but we don't have a way to look it up. The only company that lists their parts like that is Grand Design. If they can get out to their trailer and…

Answer 2

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Hey Lisa! It looks like your Arctic Fox 25R Trailer has a standard coupler, so there's no need to go with a system like the Blue Ox #BLU35FR you were looking at that's designed for the 'underslung' setup. Also, with a trailer of this…

Despite what the manufacturers of these equalizers say, the axle/wheel spacing isn't the right way to figure out the best fit for upgraded equalizers, including the MORryde CRE3000. The wheel spacing is more of a guideline, so to determine the…

The zerk fittings on the Dexter Trailer Axle #T3584F-EZ-8974 are a 1/4" pipe thread. If you need a replacement zerk fitting you can use part #Gzerk, which we have confirmed to fit the Dexter Ez-Lube Axles.

Hey Jeff! I'm not sure who told you that but the information is incorrect. The MORryde X-Factor Crossmember can be used with the AllTrek 4000 like #MR29DR. The correct X-Factor crossmember is the #MR33WR which is the same as the XF12-001. You can…

To determine the correct length shackle straps it is best to compare your current equalizer to the Road Armor Shock Absorbing Equalizer #LC696740 that you installed on your 2021 Keystone Cougar 22MLS. A basic Equalizer #AP233 that comes on your size…

Hey Rick, welcome back. The Equa-Flex Cushioned Equalizers item #LC279687 and the Dexter E-Z Flex item #K71-654-00 are pretty identical. They both have rubber cores that help absorb road shock and limit chucking. Dimensionally the Dexter E-Z Flex…
