The etrailer 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # e34SR most likely would be the correct choice for your 2020 Grand Design Reflection 337RLS, but you'll want to confirm by measuring from the center of one eyelet to the center of the other eyelet. You'll want to lift the trailer and let the axles hang down to get an accurate measurement. The # e34SR has a 25-1/4" eyelet to eyelet measurement.

For the wet bolts and shackle straps you'd need the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR. These shackle straps would also be an upgrade compared to the standard ones installed by Grand Design and with how thick they are you shouldn't ever have to replace them.

If you wanted to replace the equalizer as well you'd need part # K71-654-00, but you'd also want to measure the eyelet spacing on your current equalizers to confirm fitment. This specific equalizer's hole spacing is a 5-1/4" to 6-1/4" range since the arms can move depending on the load pressing against them.

I've attached a few of my installation videos below where I'll go over everything you'll need to know to replace your suspension components and give you a few tips to make the process easier.
