Question:
Hi, I am looking for a spare hub for my Nitro Z7 trail Star boat trailer. The marking on the back of the hub is 46210. Its 5 0n 4.5, the trailer ID is 4TM14HF12BB001681, can you tell me what hub I need? The GVWR is 3740. thank you

Hey James, thanks for the marking info you found on your hub. Based on that I can tell your trailer has 3,500 lb axles with a 5 on 4-1/2 inch bolt pattern so for a replacement you would want the part # AKIHUB-545-35-K that you referenced and you'd be set. This is also pre-greased which means it's ready to install without having to make a mess.
