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 the # AP233 will work just fine on your 2004 Carson dump trailer with axles spaced 33" to 34" apart.

If you find that you've got different sized equalizers and shackle straps, let me know what size and I'm happy to help you locate the appropriate parts.

There's not a complete kit with a 6-1/8" wide equalizer, but we can piece together the same type of kit for your trailer that's similar to the # AP233 you were looking at, that will be a better fit. I recommend starting with the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 6-1/8" Long - 9/16" Center Hole # TREQ356, which will be the same width as your old equalizer. Then, for the shackles and bolts I recommend using the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR which has 2-1/4" shackles (eye bolt to eye bolt) and comes with wet bolts to keep everything lubricated, and bronze bushings. If you wanted just basic bolts then you could use the Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # 166081, which are sold individually. You'll then add some Nylon Bushings - 9/16" Inner Diameter, 3/4" Outer Diameter - 1-3/4" Long - Qty 6 # SP05-060 and shackles # LC122487 to complete your kit.

Front and rear springs hangers should be equally spaced around the center hanger and spring equalizer. It may be that your trailer was modified (if not originally built) with a different height center hanger and that might be how the spacing became…

If your trailer has torsion axles, no worries but it it's a leaf spring suspension you really should have equalizers. Without the equalizer, the trailer will have a rougher ride and the weight won't be balanced across both axles when…

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is…

Trailer manufacturers don't usually keep a record of parts like these that they install at the factory, so I cannot be sure as to the exact length of the shackle strap that would have come originally on your trailer. With this in mind, a…

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

Since Grand Design is kind enough to list certain parts for their trailers I can confirm you have a 33" wheelbase on your 2020 Grand Design Transcend 27BHS. This means the MORryde Rubber Equalizers #MR87ZR will fit your trailer. Although I'm…

Answer 9

Yes, going from a 4 leaf to a 6 leaf spring would add slightly to your ride height. For example, if the current 4 leaf spring has 3/8" thick leaves, and you go to a 6 leaf spring with 3/8" thick leaves, you would be adding 3/4" of…

Answer 10

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…

Answer 11

There is no specific torque rating for shackle bolts. Basically for the middle bolt there should be enough free play in the shackles to allow them to move. Tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs…
