Our take on the 6 on 5.5in Pre-Greased Hub & Drum Assembly – 6K Trailer Axles, #42 Spindle, 1/2in Studs

A complete pre-greased hub and drum assembly for 6,000 lb trailer axles with a #42 spindle. It uses a 6 on 5.5in bolt pattern with 1/2in studs and fits 12in x 2in brake assemblies. The box includes bearings, pre-installed races, seal, caps, plug and coned nuts, so it is a one-box replacement rather than a bare hub. It suits owners of utility, cargo, livestock, equipment and flatbed trailers who want to swap a worn hub without packing bearings first.

Pros

  • Includes bearings, seal, caps, plug and wheel nuts in one box
  • Correct 6 on 5.5in pattern with 1/2in studs for common trailer wheels
  • Works with both grease and E-Z Lube axle systems
  • Retail boxed for clean storage or resale
Cons
  • Only fits 6,000 lb axles with a #42 spindle
  • Requires 12in x 2in brakes, so it is not a universal fit
  • Pre-greased bearings still need proper torque and inspection after install
