• Typical Hanger Spacings for Tandem Axle Trailer with 3,500 lb Axles
  A lot of it depends on the length of the springs and equalizers that are used. When using Leaf Springs # e64SR 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 trailer maintenance...

• Parts Needed to Replace Equalizer and Shackles and How to Determine Which Parts to Use
  Generally you'll want to replace your equalizer and shackles with ones that have the same or similar dimensions. The equalizer in the # AP233 kit has a 2" tall and 5-3/4" long (eye bolt center to eye bolt center) and the shackles included are 2-1/4" long. You might be able to make up the distance by just using some longer shackle straps like the Replacement Shackle Strap - 2-5/8" Long # 115052, which will give you an extra 3/8" of an inch. If you can provide the length of the shackle straps...

• Which Replacement Equalizer and Shackles for 2004 Carson Dump Trailer with Axles 34" Apart
  In addition to the axle spacing, the best way to choose the appropriate equalizer replacement is by measuring how wide your current equalizer is when measured between the two side bolt holes, center on center; as long as you keep everything relatively close in length compared to the old parts, the geometry of your suspension system won't be thrown off. As long as your existing equalizer is 5-3/4" wide and your shackle straps are 2-1/4" long from bolt eye center to bolt eye center then...

• Replacement Leaf Spring and Equalizer Kit for Trailer with 5,200 lb Axles
  For leaf springs you would want the part # e34SR which is a 25-1/4 inch long leaf spring that is rated for a 6k axle. The shorter length of this would match up well with what you have now. Then for a U-bolt kit you would want the part # APUBR-8 which is correct for 3 inch diameter axles. Then for a tandem axle equalizer and shackle kit you'd need the part # AP233 and you'd be set.

• Replacing Suspension Components On A 2005 Fabrique Boat Trailer
  I can certainly point you in the right direction. I am not able to recommend leaf springs and brackets based on a model of trailer or Vin number. If only it were so easy right? Generally only the manufacturer of the trailer will have that kind of information. When replacing leaf springs we do want the new springs to be basically identical to the old springs. The best way is for your to measure each spring. Double eye leaf springs are measured across from center eye to center eye. It is...

• Correct Length Shackles and Wet Bolts For A Lippert Road Armor Shock Absorbing Equalizer
  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 camper is generally 2" tall. The Road Armor is 3-1/2" from the mounting bolt to the center line of the shackle mounting bolts. This is why you see their Kit # LC52SV having the 3-1/8" shackle straps that will keep the spring and axle height...

• How Tight Should Shackle Link Nuts Be On Trailer Suspension
  In regards to trailer suspension kits like the Suspension Kit for Tandem-Axle Trailers part # AP233, the shackle bolt heads are indeed seating into the hangers via the knurling on the bolt. If you hold a wrench on the bolt head and tighten the nut, this will seat the knurling. The bolt does not pivot on the outer shackle links but rather the spring/equalizer pivots on the bolt. There is no torque spec for this bolt/nut, you'll stop tightening when the spring/equalizer does not have any...

• 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 looking...

• 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.

• 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.

• 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 bolts...

• Determining What Hanger Spacing For Tandem Axle Trailer Using 28-3/4" Long Leaf Springs
  I would be happy to help, but the only way to find the exact location for mounting the hangers to your boat trailer is going to be by tacking the hangers in place and moving them around until you get the suspension correct. When done correctly the shackle straps on the equalizer should point like a W like in the included picture. Your 730mm spring translates to 28-3/4" which is not a very common length so there is not exact hanger spacing anywhere for a spring that length. On all of the...
