Updated 09/15/2025 | Published 05/17/2025
Question:
Have a Grand Design 337RLS Fifth Wheel Trailer. Has the 6000 lb rating on 2 axles. Need the part numbers for the wheel bearing and the grease seals and or the kit which I assume comes with the new cotter pin. Thanks Curt60 -SBSA- 86.5 - 68.5 -NOSP - OS - L - C65517 - ABS - 7227 - Bronze- 30PT

Hey Steven, since we know you have a 6k rated axle the correct bearing kit that includes a grease seal would be the part # BK3-100. Did you have bearing issues or are you looking for a backup set to keep around just in case?
