It looks like your 2020 Grand Design Transcend M-247BH has a GVWR of 6,995 lbs so your leaf springs should be rated for 3,500 lbs. If this is true then we have a few of these and you'll just need to select the correct one based off of the length of your current leaf springs (measured center-eye to center-eye):

23-1/8" - # e59SR
25-1/8" - # e68SR
27" - # SP-210275

If you lift your trailer so there isn't any weight on the springs you'll be able to measure the length of your leaf springs and then purchase the one that matches. Please note that as a rule whatever you do to one side of an axle you'll need to do to the other side so your trailer ride remains consistent.

I checked directly with Dexter, and from what I saw they have a measurement - taken from center of spring eye to center of spring eye - of 24.8", which is the same as our 24-7/8" measurement for the 7-Leaf Double-Eye Spring for 8,000-lb…

While the standard axle diameter for a 3,500 lb trailer axle is 2-3/8 inches it's not unheard of to see a 3 inch diameter 3,500 lb axle. All of our 3,500 lb axles like the part #7359765 are 2-3/8 inches.
