SEHNSUCHT Trailer Electric Brake Kit — Pair 10" x 2-1/4" Manual Adjust, 5-on-5" Hubs for 3500 lb Axles

SEHNSUCHT's kit includes two 5-on-5" brake drums and a matched pair of 10" x 2-1/4" manually adjusting electric brakes engineered for 3,500 lb trailer axles (fits 1-1/16" to 1-3/8" spindles; not for 5-on-4.5" or Nev-R-Lube axles).

This all-in-one replacement assembly combines corrosion-resistant iron drums, sealed bearings, hub hardware and a left/right electric brake set so you can restore stopping performance quickly. The drums are electroplated to resist rust, the kit supplies common bearings and seals, and the electric brakes are pre-configured for manual adjustment. Read on for fit, installation details and what’s in the box so you can confirm compatibility before you buy.

How do I know this kit fits my trailer axle?

Confirming fit requires three quick measurements: hub bolt pattern, spindle journal diameter and axle lubrication style. This kit is designed for a 5 on 5" bolt circle, spindles between 1-1/16" and 1-3/8" diameter, and standard (non-Nev-R-Lube) axles.

• Bolt pattern: 5 on 5" (not compatible with 5 on 4.5").
• Spindle size: fits 1-1/16" to 1-3/8" spindles.
• Axle type: standard lube axles only; not for Nev-R-Lube or certain Airstream models built after July 2005.

What components come with the SEHNSUCHT brake and hub assembly?

The package bundles the drum pair, bearings, seals, dust caps and a matched set of electric brakes with mounting hardware so you receive everything needed to rebuild a hub and brake system for two wheels. Hardware counts are provided to make inventory straightforward during installation.

• 2 x 5 on 5" brake drums/hubs with electroplated finish for corrosion resistance.
• Bearing inner races: replacements for L68149 and L44649 sizes; grease seals and dust caps included.
• 2 x 10" manual-adjust electric brakes (left and right), hub nuts, washers, cotter pins, and related hardware.

How do these drums and electric brakes perform in real use?

Manufactured from high-grade iron and finished with electroplating, the drums resist rust and hold up in variable conditions. The electric brake assemblies are built to deliver predictable response when actuated and include manual adjusters for field tuning.

• Electroplated drum bodies reduce corrosion and extend service life.
• Classic drum geometry offers reliable friction response and emergency stopping capability.
• Manual adjust brakes provide on-trailer adjustability and include spring/nut hardware for installation.

What should I watch for during installation?

Check flange dimensions and hub fit before mounting, and note that the dust cap requires a press or light hammering to seat correctly. Ensure bearings are packed with grease and torques follow manufacturer specifications to avoid premature wear.

• Measure brake flange and bolt pattern before starting installation.
• Install dust caps by carefully seating them with a mallet or press; avoid deforming the cap.
• Pack bearings with quality grease and torque hub nuts to spec; use cotter pins where required.

Who is this for: This SEHNSUCHT kit is aimed at trailer owners, DIY mechanics and repair shops rebuilding hubs and brakes on 3,500 lb axles that use a 5-on-5" bolt pattern and standard lube spindles. It’s ideal if you need a complete hub/drum and electric brake replacement with all common bearings, seals and hardware included—just confirm your flange pattern and axle type before purchase.
