trailer spindle and hub kits

Product Overview

This heavy-duty trailer-specific idler hub kit (5200-7000lb load capacity, 6 on 5.5 bolt pattern, #42 spindle) is engineered for medium-to-heavy-duty use—critical for maintaining trailer safety during regular inspections. It fits utility, commercial, and RV trailers seamlessly, delivering stable load-bearing and smooth rotation that simplifies wear detection during routine checks.

Core Specifications

Custom options (tailored to your inspection and usage needs): tail size (standard custom feature), bolt patterns, load capacity calibrations, corrosion-resistant material upgrades (easier to clean and inspect for rust), and reinforced bearing systems (extends inspection intervals while reducing failure risks).
