Review of Dexter Axle Trailer Leaf Spring Suspension - Spring Mounting Hardware - K71-448-00 Video

The standard diameter for trailer leaf spring bolts is 9/16 inch which is why the part #E4139 and all similar options have this hole size. We don't have anything with a smaller diameter but my guess is what you have is actually 9/16 inch.

Yes, the 2-1/4" Long MORryde Suspension Upgrade Kit item #MR86ZR will lower your trailer's frame closer to the ground. The only effect it will have is to ever so slightly reduce your suspensions travel. The MORryde Suspension Upgrade…

Hey Rob, the bolts that come with the equalizer kit part #AP233 that you referenced are Grade 5.

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…

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…

The shackle straps included in the Lippert Tandem Axle Equa-Flex AP Kit - Wet Bolts - 3-1/8" Long Shackles #LC64FR you mentioned are 3-1/8" center to center and 4-3/8" overall length as shown in included diagram. Using the…

Both the MORryde Rubber Equalizers #MR87ZR and Dexter E-Z Flex Suspension Kit #K71-652-00 are achieving the same result. They are doing so with slightly different designs but end up with the same result. I recommend using the Dexter E-Z Flex…

The equalizers that come with the Dexter Heavy-Duty Suspension Kit #K71-448-00 have bolt holes that measure 6" apart on center and then 4" tall on center as you can see in the attached photo. You'll want to measure your…

Excellent question, and the difference between the two kits comes down to the dimensions of the equalizers. What you will want to do is match up the size of your equalizer with the size of the equalizer in these kits. - 6" Long, 4" Tall…

The correct replacement for a Dexter 13-10 Equalizer is the Triangular Equalizer part #TREQ310, not the Curved Equalizer part #TREQE1. If you want to upgrade, the Equa-Flex Cushioned Equalizers part #LC279688 would work but you might want to go with…
