The only way to know for sure if the 1/4 inch longer shackle straps, # TRSL225 (compared to the 2 inch long # TRSL200) will be a problem is to install them. The longer straps will likely mean they will be at a steeper angle once installed and that could affect the travel of the suspension.

I do recommend not chancing it and go ahead and get the correct shackle straps # TRSL200.

Answer 1

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer (if possible); replacing them with longer straps will result in additional play in your trailer suspension which could lead to…

First, thanks so much for the detail you provided, it super helpful, and what you have is the Triangular Equalizer #TREQ310. This is one of the longer and taller equalizers, but since you have a 33 inch wheelbase, there is an option for you, from…

Answer 3

Considering all that has been done so far, I think the first step I would take here is to go with the shorter shackle straps. If you're still getting contact with the trailer frame, I would then take a look at upgrading to a taller equalizer like…

Answer 4

I do have an upgrade option for your 6-1/16" long, 4" tall Equalizer #TREQ310, and since you don't want to lower the ride height with the E-Z Flex #K71-652-00, I recommend going with an option from MORryde, as the Equa-Flex are just too…

Answer 5

I attached a picture that shows the proper position of shackles and equalizers on trailer suspension. Sometimes the shackle will flip up but if you jack up the trailer by the axle that's got the shackle flipped you can usually get it to flip back…

Answer 6

The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. You should have sufficient clearance with your loaded trailer, as leaf springs only tend to deflect 1-1/2 inch when carrying a load.

Answer 7

To slightly lower your trailer that has had an "axle flip" kit installed you would want to use slightly shorter shackle straps, not longer ones. Shorter shackles will let the axle rest closer to the trailer frame, which lowers the trailer…

Hi Paul, you’re definitely on the right track here, and I can help you narrow this down with confidence. With your tandem 3,500 lb Dexter axles and 33 inch spacing, both the Dexter EZ Flex part #K71-652-00 and the Lippert Road Armor part #LC53CK are…

Answer 9

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Answer 10

Hey Ian, great to hear from you again! The differences between the MORryde CRE3000 #MR87ZR and AllTrek 4000 #MR89DR that fit a 33" wheelbase is the height between the hanger and equalizer bolts, and the amount of travel the suspension style will…

Answer 11

We have lift kits for trailer that easily add 2 inches to the height of the trailer. For that you'd want the part #RR23QX and you'd be set. I attached a picture that shows how it installs to give you an idea. This would be the easiest…
