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?
