Based on your images it does appear your trailer was built to have double eye springs rather than a slipper spring. For this you will need to measure your current mounts from bolt hole center to bolt hole center. We have the 3,500LB leaf springs…

Since you have 3,500 lb axles you most likely currently have 3,500 lb axle leaf springs which we have in a 4 leaf spring with part #e68SR. This is 25-1/8 inches long which is a very common length and most likely your best option. But without knowing…

Although they are not rated significantly higher, installing the #e57SR could result in a noticeable difference in the ride. Springs rated for your 3,500 lb axle (1,750 lb spring capacity) would be the better option. I'm not sure what you had…

From my research, it seems that a combination stapling the carpet to the bunks using stainless or Monel (primarily an alloy of copper and nickel) staples and outdoor carpet adhesive is the preferred method of attaching carpet. I replaced the bunks on…

The bunk brackets will attach to the trailer cross members using U-bolts. Since you don't need a swiveling bracket, the #CE10600G bracket you mentioned would work fine. I've provided a photo showing how the bunk board attaches to the bracket,…
