• Replacement Leaf Spring for 2015/2016 Riverside Retro 195
  Hi David; you will have to measure your other leaf spring to find the right replacement. I recommend measuring the flat length to get the most accurate measurement, see the article linked further down on this page. For example, if you found that the overall flat length was 26-3/8", or the eye to eye measurement was 25-1/4", you could use the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles # e54SR. If you have a different measurement let me know in the comments below and I'll see what...

• 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...

• Will Longer Equalizer Cause Problems for Trailer Suspension
  Hi Chip; you might be able to get by with that, but I don't think it is worth risking issues with your suspension. As far as equalizers go it is quite a bit longer than your old one. Standard equalizers are pretty inexpensive, and a problem would potentially be very expensive, so I would get an equalizer that matches. I see your old equalizer is marked 13-10 but it doesn't line up with the standard 13-10 design. If you can measure your old equalizer and add those dimensions to the comments...

• 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...

• How To Determine What Size Leaf Springs, Equalizers And Shackles I Need
  Hello Jbryan, thanks for getting in touch. I wish I could tell you that based on the hanger spacing, but that just isn't enough info for me to give you precise numbers. If you are needing to replace your springs, equalizers and shackles, you will need to measure what you have currently. Leaf springs should be measured when unloaded, and are measured from eye to eye straight across. For the equalizer you will want to measure the length and height from center hole to center hole. Same for...

• Parts Needed to Convert a Torsion Axle Trailer to a Tandem Spring Axle
  Hey George, what do you mean by narrow equalizer? What size equalizer do you have right now? To convert your trailer's torsion axles to spring axles, you'd need to have new hangers welded on, leaf springs, and a new axle. For new hangers, you can use # APT8 which'll work best with axles that are rated between 2,000 and 7,000 lbs. For springs, you can use the # TRU42FR you were looking at with the U-bolt kit # APUBR-10. Finally, for an axle, you're going to need to measure or know the...

• 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...

• 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 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...

• 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...

• 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 # e27SR 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" # e54SR, but I would be hard pressed to believe that your old ones have stretched out over a full...
