Dexter Axle Hub and Rotor Kit, 3.7K 545, Cupped and Studded, Zinc Finish

This Dexter Axle hub and rotor kit is a single boxed hub/rotor assembly built for 3.7K capacity trailer axles using the 545 hub configuration. The unit is cupped and studded, meaning the bearing cups and wheel studs are pre-installed at the factory, simplifying installation onto a matching 3.7K 545 trailer axle spindle. The hub and rotor are finished in zinc for corrosion resistance during service on boat trailers, utility trailers, and other towed equipment exposed to road spray and moisture.

Each kit ships as one complete hub and rotor unit, ready to be paired with the correct bearings, seal, and caliper hardware for the axle it is installed on. The zinc-plated finish helps protect the rotor and hub surfaces from rust while in storage or use, and the pre-studded design reduces on-axle assembly time compared to installing studs individually.
