Buying Guide
What spindle type do you have? Choose tapered spindles kits for EZ-Lube tapered axles and straight spindles kits for straight axles. Confirm bearing sizes (L44649 vs L44643) and inner/outer bearing compatibility before buying. Look for prelubed or preinstalled races if you want faster installation. Consider additional dust caps, seals, and corrosion-resistant finishes for longer life in marine environments.
What capacity do you need? Most listed options target 2000 lbs or 3500 lbs. Match the axle rating to avoid overloading the hub kit and to ensure safe operation on the road and on water.
What’s included? Some kits come with extra seals and dust caps. If you’re performing roadside maintenance, an all-in-one kit with spare parts reduces downtime.
