FAQ
What is a sealed boat trailer hub?
A sealed boat trailer hub encloses bearings with seals and grease to protect against water intrusion and debris, reducing maintenance frequency.
Which hub is best for a straight spindle?
Most kits labeled for straight spindles with L44649/L68149 bearings are ideal for 1-1/16″ to 1-3/8″ straight spindles on 2000–3500 lb axles.
Can I mix hubs from different brands?
Mixing hubs is not recommended; ensure compatible bearings, seals, and bolt patterns within a single installation.
How do I verify the bolt pattern?
Measure the distance across from the center of one lug hole to the center of the opposite lug hole. For 5 lugs, a 4.5″ measurement indicates 5×4.5″ bolt pattern.
Are pre-assembled hubs easier to install?
Yes. Pre-assembled hubs save installation time and help ensure bearings and seals are correctly seated, provided the spindle size matches.
