SEHNSUCHT 12 x 2 in Trailer Brake Drum Kit, 6-Hole 5.5 in Bolt Circle — Electroplated Iron for 5200–6000 lb Axles

SEHNSUCHT's 12" x 2" trailer brake drum kit is a complete, corrosion-resistant replacement hub assembly engineered for 6-hole, 5.5" bolt-circle spindles on 5200–6000 lb axles.

This replacement brake drum kit bundles a 12" x 2" iron drum with essential bearings, seal, dust cap and mounting hardware so you can restore braking performance on standard-lube trailer spindles. The drum is electroplated to resist rust in marine and road environments, and it’s designed to fit #42 spindles using 6-hole, 5.5" bolt patterns commonly found on RVs, utility trailers and light semi applications rated 5200–6000 lb.

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

The kit arrives with everything needed to replace a single hub drum assembly: the stamped iron drum, inner bearings, grease seal, dust cover, rubber dust plug and six hub nuts. Having matched parts packaged together reduces the chance of mismatched bearings or missing hardware during installation.

• 1 x 12" x 2" electroplated iron brake drum
• Bearing replacements: 25580 (I.D 1.75", O.D 3.263") and 15123 (I.D 1.25", O.D 2.44")
• 1 x grease seal (I.D 2.229", O.D 3.372", height 0.375")
• 1 x stamped dust cover (mounting dia. 2.448") and 1 x rubber dust plug
• 6 x 1/2-20UNF hub nuts for secure mounting

How do I know this drum fits my axle and spindle?

This drum is built for 6-lug wheels with a 5.5" bolt circle and is intended for use on #42 spindles and standard-lube axles rated between 5200 and 6000 lb. It is not compatible with Nev-R-Lube or certain Airstream Classic trailers built after July 2005.

• Fits 6-hole, 5.5" bolt circle wheels
• Compatible with #42 spindles and 5200–6000 lb axles
• Not for Nev-R-Lube axles or Airstream Classic (post Jul 2005)
• Designed for standard lube axle assemblies

What installation notes and tools should I expect to use?

Installation follows standard drum/hub replacement steps: remove the wheel and old drum, inspect spindle and bearings, press or seat new bearings and seal, then secure dust cover and nuts. The dust cap must be driven in by hammering — use proper bearing grease and torque specifications for safe assembly.

• Wheel removal, drum puller or careful pry to remove old drum
• Clean spindle, inspect for wear; replace bearings if scored
• Press or tap bearings and seal into drum, pack grease as required
• Drive dust cap in place with a soft-faced hammer and torque hub nuts to spec

How does the finish and material affect longevity?

The drum body is cast from high-strength iron and receives an electroplated finish to reduce surface corrosion and extend service life in wet or salty conditions. While plating slows rust, periodic inspection and proper lubrication remain important for long-term performance.

• High-quality iron construction for structural durability
• Electroplated exterior to resist rust and environmental wear
• Designed to withstand road and marine exposure with routine maintenance
• Service life extended when bearings and seals are properly greased

Who is this for: This SEHNSUCHT 12" x 2" drum kit is intended for trailer owners, RV technicians and fleet managers who need a direct-fit replacement hub assembly for 6-lug, 5.5" bolt-circle wheels on 5200–6000 lb standard-lube axles. It’s a practical choice when you want a complete, corrosion-resistant drum package with matched bearings and hardware to simplify a single-drum service or replacement.
