Thanks for the information Eric! To replace a single wet bolt in your 2019 Grand Design Reflection 312BHTS suspension you'll need the Step Wet Bolt for 1-3/4" Double Eye Springs item # 34007-187-00. This is an exact replacement for the step bolt that came with the Dexter suspension on your travel trailer.

There is not a specific torque setting for suspension bolts, like item # 34007-187-00. All you have to do is tighten the bolt until the knurled portion of the bolt pulls completely into the shackle strap and the bolt head is ran all the way down to the shackle strap.

You'll also need the Replacement Flange Nut for Dexter Trailer Suspension Kits item # 006-092-01. The nuts and bolts are only meant to be tightened down once so you'll want to replace both.

What happened to your suspension bolt?

Upon replacement I found that the plastic bushing needs replaced as well. What is the part number for that?

@EricZ The Nylon Bushing item # TRBU11566 would be the correct one for your Grand Design's leaf springs.
