Hey Carl, thanks for reaching out. We will definitely have a wet bolt/bronze bushing kit for you. If you're wanting wet bolts and bronze bushings, it'll be more cost effective to get a whole suspension kit complete with HD shackles, wet bolts and bushings. We will just need to confirm the size of the stock shackles to make sure we match that up. They should be either 2-1/4" or 3-1/8" long center hole to center hole but please confirm. Then pick from the following based on your shackle size:
- MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR
- MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR
These MORryde kits are definitely the best bet for an upgraded shackle kit. Its super durable stuff and for a good price too.
Any other suspension parts you were looking to replace? Need a new equalizer too?

I replaced all 4 of my springs, installed MORryde CRE equalizers as well as the spring pin update kit on my 18 GD 2600RB, best thing for it. No popping suspension or falling items in the trailer while towing. Smoother over bumps and RR crossings as well. Keep them greased! I unload the suspension before greasing them. (frame jack)

The whole kit worked for me everything fit perfectly, took out all that plastic trash and replaced all of everything that was OEM with the what was in the kit. The only thing I will tell you is to make sure you don’t turn one of your equalizers around everything else was fine.

I replaced my sagging leaf springs on my Jayco pinnacle fifth wheel. While I had it apart I upgraded to heavy duty shackles and wet bolts. I think they will be good for the life of the trailer.
