SEHNSUCHT Trailer Idler Hub Kit 5‑Lug 4.5" Bolt Pattern — Set of 2 for 3,500 lb Axles, Tapered Spindle 1-1/16"–1-3/8"

SEHNSUCHT Trailer Idler Hub Kit is a 5-lug, 4.5" bolt pattern hub assembly engineered for 3,500 lb axles and tapered spindles from 1-1/16" to 1-3/8", supplied as a set of two with bearings, seals, dust caps, and nuts.

This kit brings together the main components you need to refresh or upgrade idler hubs on small to medium trailers and boat trailers. Built from plated iron with replacement bearings and seals included, the package is ready for installation on compatible tapered spindles (#84 spindle specification). The design focuses on corrosion resistance, straightforward fitment, and maintenance-friendly service life for trailering and marine use.

Will this hub kit fit my trailer spindle?

The SEHNSUCHT idler hub kit fits tapered spindles sized between 1-1/16" and 1-3/8" (commonly #84 tapered spindle). It is not compatible with straight spindles of 1-1/16" or 1" diameter. Confirm your spindle type and taper before ordering to avoid mismatch during installation.

• Compatible: tapered spindles 1-1/16"–1-3/8" (#84)
• Not compatible: 1-1/16" straight or 1" straight spindles
• Bolt pattern: 5 lug, 4.5" (center-to-center spacing)
• Intended axle rating: 3,500 lb

What components are included in the set and why they matter?

The kit supplies two complete hub assemblies plus the bearings, seals, dust covers, and hub nuts required for installation. That means you get both inner and outer bearing races, oil seals to protect against contamination, and mounting hardware sized for the hub, minimizing the need for additional parts.

• 2 x 5x4.5" idler hubs (set of two)
• 2 x inner bearing races (replaces L68149)
• 2 x outer bearing races (replaces L44649)
• 2 x oil seals, 2 x dust covers, 10 hub nuts (1/2-20 UNF)

How durable and corrosion-resistant is the hub construction?

Hubs are made from high-quality iron and finished with electroplating to resist rust and corrosion in wet, salty, or humid conditions. The plating extends service life and helps reduce maintenance frequency when used on trailers and boats that encounter water or road salt.

• Material: plated iron for strength and longevity
• Protection: electroplated finish for corrosion resistance
• Designed for trailer and marine exposure scenarios
• Includes seals to keep bearings free from contaminants

What are the installation and torque recommendations?

Follow staged torque values and final settling steps for safe, reliable installation. Pre-tighten, tighten, and then torque after the trailer is lowered to ensure proper bearing preload and prevent looseness or overheating.

• Pre-tighten torque: 60 N·m
• Tighten torque: 100 N·m
• Final torque after lowering trailer: 150 N·m, tighten diagonally
• Use recommended nut sequence to ensure correct seating

Who this hub kit is for: The SEHNSUCHT 5-lug idler hub kit suits trailer owners, boaters, and repair professionals who need a full, ready-to-install replacement set for 3,500 lb axles with tapered spindles. Choose this set when you want included bearings, seals, and hardware tailored to 4.5" bolt pattern wheels, especially for trailers that see moisture, salt exposure, or frequent use. If your spindle is straight or outside the 1-1/16"–1-3/8" tapered range, select a hub designed for that specific spindle type instead.
