Each pair of Boat Trailer Deluxe Roller Bunks # DL21740 have a 2,500 lb. capacity. Your bigger consideration will be the length because with needing multiple pairs of rollers, you will have enough weight capacity.

Typically you will want to match the length of your current bunks with the news ones. But a good rule of thumb is to have at least 50% of the length of your boat. I have included enough bunk rollers and parts needed for that below.

Bunk Rollers
- Boat Trailer Deluxe Roller Bunks # DL21740 (x3) gives you 12' of rollers, slightly over 50%.

You can either attach these to your current bunks or you can use the CE Smith Bolster and Swivel Bracket Assemblies for Roller Bunks # CE10003G-4 (x3) with the CE Smith U-Bolts # CE15283GA-4 (x3).
