SEHNSUCHT Trailer Electric Brake Kit — 12" x 2" Self-Adjusting Brakes, 6-on-5.5" Drums for 5200–6000 lb Axles (Pair)

SEHNSUCHT's Trailer Axle Electric Brake Kit is a complete pair of 12" x 2" self-adjusting electric brakes with 6-on-5.5" brake drums designed to upgrade or replace assemblies on 5200–6000 lb standard-lube trailer axles. This kit bundles durable iron brake drums, matching bearings and seals, dust caps, hardware, and one left plus one right self-adjusting electric brake so you can service a tandem or single axle reliably. Components are electroplated or treated to resist corrosion, and the brakes are pre-configured for a 12" x 2" shoe size to match common trailer applications — giving you a ready-to-install replacement that reduces parts hunting and potential fitment surprises.

Will these brakes fit my trailer axle and hub pattern?

These drums use a 6-on-5.5" bolt circle and are intended for standard-lube axles rated around 5200–6000 lb. They are compatible with many Dexter-style hubs and other common brands, but they are not compatible with Nev-R-Lube axles or certain Airstream Classic models built after July 2005.

• Bolt pattern: 6 on 5.5" (6x5.5)
• Brake size: 12" diameter x 2" width shoes
• Rated axle capacity: 5200–6000 lb
• Not for Nev-R-Lube or specific Airstream Classic post-2005 axles

What parts come in the kit and what are their specifications?

The package includes two brake drums, inner bearing replacements, grease seals, dust covers, hub nuts, and a matched pair of left/right electric brakes, plus the bolts and washers needed for installation. Bearings supplied replace 25580 and 15123 inner races; grease seals and dust covers match standard hub dimensions for this drum type.

• 2 x 12" x 2" brake drums (6 on 5.5" bolt circle)
• 2 x bearings for 25580 and 15123 sizes and 2 x grease seals
• 2 x dust covers, 2 x rubber dust plugs, 12 hub nuts, and mounting hardware
• 1 left and 1 right self-adjusting electric brake included

How durable and corrosion-resistant are these drums and brakes?

The drums are cast from quality iron and finished with electroplating to resist rust and pitting that shorten service life. The self-adjusting brakes are built to respond promptly in demanding conditions, and included seals and dust caps help keep contaminants out of bearings and braking surfaces.

• Electroplated drum surface for improved rust resistance
• Sealed bearings and dust caps to limit contamination
• Self-adjusting brakes maintain shoe-to-drum clearance during use
• Hardware and fasteners sized for reliable reassembly

What should I check before ordering and installing this kit?

Measure your current hub bolt circle, confirm axle lubricant type, and verify bearing and seal dimensions to ensure compatibility. Note that the dust cap requires light hammer installation and this kit is for standard-lube axles only; measure the brake flange and hub face before beginning work.

• Confirm 6 on 5.5" bolt pattern and 12" x 2" brake shoe size
• Verify axle is standard-lube (not Nev-R-Lube) and not Airstream post-July 2005
• Measure bearing inner/outer diameters and seal dimensions supplied
• Plan basic tools: torque wrench, press or driver for dust cap, bearing packer

Who is this for? If you maintain or upgrade medium-capacity trailers (around 5200–6000 lb), tow frequently, or need a complete, bolt-on replacement set to restore braking performance, this SEHNSUCHT kit provides the parts and matched brakes required for a comprehensive axle service. It suits DIY mechanics and professional shops that want a corrosion-resistant drum, correct bearings and seals, and matched left/right electric brakes all in one package. For specialized axles like Nev-R-Lube or certain Airstream Classic models, consult your axle documentation or a technician before purchasing.
