Question:
Hi, I need some help here. I want to replace the seals on my 2008 boat trailed. It has the Trailer Buddy axles by UFP with The Vault hybrid lube. I have a dual axle trailer, it has 1.98 bore. I want to get 4 inner seals, o-rings, bearings, the outer stainless steel protector, grease and anything else required to do this. Do you offer kits for this? Do you need any more info? Thanks, Chad

Hey Chad, we do have Dexter Vault kits like it sounds like you are looking for but it comes down to what capacity axle you have to determine which kit you need.
# DX52UR is for 2500 to 3500 lb axles
# DX23ER is for 4200 to 5200 lb axles
# DX83ER is for 6k axles
# DX73ER is for 7k axles.
Since you mentioned 1.98 inch diameter its very likely what you need is the part # DX52UR for 3,500 lb axles.
