2020 TRD OffRoad Leafspring rating

I have been searching the web trying to find out the exact specs as it relates to the load capacity of each factory installed leafspring on the 2020 TRD Off Road 4x4. I had the factory swapped out over a year ago (they only had 6,000 miles of use on them) and upgraded to a heavier duty pair of leaf springs with 2.5” lift. I still have the originals in my garage and have been thinking of installing them on a 6x10 flatbed utility trailer I was given that needs a little rehab. Any thoughts or knowledge of the specs for these leafsprings? I would have to have some custom brackets welded on to the frame to allow the longer springs to fit properly.

 

I’ve never seen much for specs listed for any leaf pack. You can probably assume they are built to handle at least half the 3rd gen Tacoma GVWR of 5600 lbs.
