• Equalizer Kit Replacement Recommendation for Equalizers that are 7-1/2 inches Long
  Since your equalizers are longer than what we have kits for you'll need to piece the kit together you'd need to replace the equalizers, bolts, shackles, and nuts. For the equalizer you'd need to start with the part # TREQE1, then for bolts I'd recommend the wet bolts part # 126B2, for shackles you'd want the part # 115052 which are 2-5/8 inches long.

• Replacement Trailer Suspension Parts for Trailer with 2 Square Axle
  It looks like you've got a pretty good grasp on all of this and thank you for the detailed information; it looks like most of the parts you've mentioned will work for you. For the leaf springs, the 26" long # SP-051275 will be the best option for you since springs stretch out over time and they're right around the capacity of what the axles likely is. The next closest size would be the 25-1/8" # SP-212275, but I would be hard pressed to believe that your old ones have stretched out over...

• Replacement Trailer Suspension Components For Tandem Trailer
  We do not have any equalizers with the dimensions you mentioned. From the looks of the photo you sent it appears the hole may be elongated and you may be able to use an equalizer that has all of the holes at 9/16-inch like part # TREQ356, or with a center hole that measures 3/4 inch like part # TREQ458. You will need to measure the equalizer length and height as well as the holes like the attached drawing shows to find the correct replacement. It looks like the shackles and...

• Do I Need Shorter Straps or Taller Equalizer for My Trailer with Double Eye Leaf Springs
  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 the Dexter EZ-Flex # 013-144-03 or you could have the front and rear hangers cut off and welded back on 1/2" further from each other in each direction. I've linked our selection of shackle straps to this question so you can find what you're...

• Can 5-3/4 Inch Tandem Axle Equalizers be Replaced with 5-5/8 Inch Equalizers
  The Tandem-Axle Equalizer Kit, # AP233, will work as long as all other measurements are the same. Check that your shackle straps are 2-1/4 inches from center hole to center hole. The 5-3/4 inch long equalizer, # TREQ104, we carry is a direct replacement for the 5-5/8 inch long equalizer.

• How Tight Should Trailer Suspension Hanger/Equalizer Bolts Get Torqued
  Suspension bolts are not designed to be torqued down tightly as this prevents the suspension from being able to move like it needs to be able to do. So the included solution with the kit part # AP233 is the lock nuts of the kit. The nuts have nylock in them which means that they will not back off regardless of how "loose" they are installed on the bolts. Basically you tighten the nuts down so that the excess side to side movement is removed from them but the shackles can still freely move...

• Are Bushings Required with the Tandem-Axle Trailer Equalizer Kit # AP233
  The equalizers of the part # AP233 have bushings in them already. The leaf springs you would use these with would already have bushings as well most likely. Typically people do not need to buy bushings with this kit or with this kit plus leaf springs.

• How to Choose the Correct Equalizer
  There is unfortunately no master list of every part number of every model of every year of trailer, so you would need to measure to find replacements. For example, equalizer # TREQE1 fits 1-3/4" wide, double-eye leaf springs with 9/16" spring eyes, has bolt hole diameters of 9/16" and is 7-3/4" from center of bolt hole to center of bolt hole.

• Trailer Equalizer Kit Recommendation that are 5 inches Long
  Best option we have would be the part # APT5 which comes with equalizers that have outer bolts that are 5-3/4 inches apart on center which would be close enough to work in your application. The shackle straps are 2-1/4 inches long and the bolts are 9/16 inch which is the standard diameter for trailer suspension bolts.

• Hanger Spacing for 3500 LB. Tandem Axle Trailer
  Thank you for purchasing from etrailer! You did a great job selecting compatible parts. When using Leaf Springs # SP-198275 with the # AP233 Equalizer Kit and the # H248 Hanger Kit, there should be 29-1/2" between the front and center hangers and 29-1/2" between the center and rear hangers. This should achieve a 4-1/2" clearance between the center of the axle and the trailer frame if you have a 3500 lb axle. I've Provided a diagram that should be helpful. I've also provided a link to our...

• Hanger Kit Recommendation for Equalizer that Measures 7-3/4 inches In Length
  7-3/4 inches from front hole center to back hole center of an equalizer is a pretty common size. For a replacement you'd want the part # TREQE1. Then for hardware we have the Never Fail Kit part # LC281285 which comes with a set of very durable bushings that are self lubricating which means no maintenance!

• Tandem Axle Equalizer Kit Recommendation with 6-1/8 inch Long Equalizers
  I can piece you together everything you need, but there isn't a kit like the part # AP233 that you referenced that has a 6-1/8 inch long equalizer. First you would want the part # TREQ356 as an equalizer. You would need two of them. A quantity of 8 of the shackle straps part # TRSL225 14 of the bolts part # 166081

• Are Nuts that Come with Trailer Suspension Kit # AP233 Lock Nuts
  The threads of the nuts that come with the Suspension Kit for Tandem-Axle Trailers # AP233 that you referenced are considered lock nuts. They should thread pretty tightly once the nut gets significantly onto the bolt which prevents it from backing off.

• Do Trailer Suspension Equalizer Kits Come with Leaf Spring Bushings
  Most leaf springs for trailers come with bushings so the equalizer kit part # AP233 does not include them. We offer some bushings though if you are in need of them. I attached a link to a page that has all of them. You will need to determine the inner and outer diameters that you need plus the width. A very popular one is the part # TRBU11566 that has an ID of 9/16 inch, is 1-3/4 inches long and has an OD of 11/16 inch.

• What Is Normal Deflection Of Leaf Springs On Trailer
  The typical spring deflection for leaf springs on a trailer is up to 1-1/2 inches when at capacity. The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches. It sounds like you have a little more than that since you flipped your axle. Leaf springs only tend to deflect about 1-1/2 inches when carrying a load.

• Finding Correct Replacement Tandem Trailer Axle Equalizer Kit
  As long as the new equalizer has the same hole spacing as the existing equalizer, it'll work just fine. You'll also want to make sure the height of the equalizer is also the same. Put a ruler across the center of the two bottom bolt holes, and measure up to the center to the top bolt hole. If this distance is about two inches, then the # AP233 would be the correct replacement.

• Should Nylon Bushings in Tandem-Axle Trailer Equalizer Kit AP233 Be Greased
  When installing Tandem-Axle Trailer Equalizer Kit # AP233 or a similar kit you will probably find it easier to insert the shackle bolts into the bushings if you lightly grease the bolts. A small amount of lubrication will both aid installation and provide a degree of lubrication for the whole assembly. You can use a general-purpose lithium grease like # L11316.

• Available Shackle Link Hole Spacing
  The shackle straps included in kit # AP233 are the part # 18-11GALV. The hole spacing, center to center, is 2-1/4-inches. The shackle strap closest to 2-1/2-inches is part # TRSL256, on which the center to center hole spacing is 2-9/16-inches.

• Should Shackle Bolts on Trailer Suspension Get Lubrication
  Yes, I would recommend keeping the bolts of the # AP233 lubricated. An easy way to do this is to use wet bolts like part # 126B2 which have a zerk fitting that allows for easy application of grease to them. Or you can use Never Fail Bushings like part # LC279684 that don't require any lubrication.

• Replacement Trailer Shackle Recommendation to Replace Shackle that is 2-1/2 inch on Centers
  The closest shackle we offer to the 2-1/2 inch size you need is the part # 115052 which is 2-5/8 inches from hole center to center. This would only be 1/8 of an inch larger than what you need so it would work well.
