Youxmoto 12 x 2 Trailer Brake Drum Kit for 5200 lb Axles
Best for: Trailers using 6-on-5.5″ bolt circle Dexter or similar 5200–6000 lb axles. This kit includes a 12″ x 2″ brake drum assembled with six 5.5″ bolt holes, plus inner bearing replacements, a grease seal, and a dust cover. It is positioned as a direct replacement for standard lube axles. Use this if you need a ready-to-install drum set without shopping for separate bearings and seals.
Why selected: Direct replacement option reduces compatibility concerns for common Dexter-based axles and avoids guessing on matching bearings or seals. It consolidates essential components in one kit, improving install efficiency.
Caution: Not compatible with Nev-R-Lube or certain Airstream Classic trailers built after July 2005. Verify axle type before purchase; this kit is for standard Lube AXLE systems.
LIBRA Trailer 6×5.5″ Hub Drum Kit + 12″x2″ Brakes
Best for: 6-on-5.5″ bolt pattern axles in the 6,000–7,000 lb class. This kit pairs two hub drums with 12″ x 2″ self-adjusting electric brakes, plus bearings, seals, and wheel hardware. It suits users upgrading an entire brake system on a larger trailer.
Why selected: Includes both the drums and the self-adjusting brakes, providing a complete, install-ready solution that aligns with common Dexter-type axles. The comprehensive kit minimizes separate shopping steps.
Caution: Designed for 6–7k lb axles; confirm your axle rating matches kit capacity to avoid over- or under-sizing brakes.
RV MURTS 12″x2″ Electric Brake Hub Kit
Best for: Trailers with 5,200–7,000 lb axles needing reliable self-adjusting brakes. The kit includes 12″ x 2″ electric brakes with included bearings, seals, castle nut, and cotter pin—without actuator or hydraulic lines. It targets straightforward installations on standard brake setups.
Why selected: Emphasizes smooth braking during forward stops and high-speed operation by providing balanced bearing components and a standard 6-bolt drum. It is a practical choice for improving braking consistency.
Caution: Does not include hydraulic lines or actuators; installation requires compatible wiring and control hardware on your trailer.

Why selected: A direct replacement option for improving ride quality and load handling on larger trailers. The kit’s multiple leaves distribute weight and reduce flex under heavy loads.

Buying Guide
- What size and bolt pattern do I need? Verify bolt circle measurements (e.g., 6 on 5.5″, 8 on 6.5″) and stud size to ensure compatibility with your current drums, hubs, and axles.
- Axle rating and type: Confirm your trailer axle rating (5,200–7,000 lb, etc.) and whether the system uses standard lubed axles or special Nev-R-Lube configurations before selecting parts.
- Brake type: Choose between drum and electric self-adjusting brakes based on maintenance preferences and installation feasibility. Self-adjusting brakes simplify routine service.
- Complete kits vs. individual parts: Kits save time and ensure compatible components (bearings, seals, grease caps, and nuts) are included. Individual parts may require separate measurements and sourcing.
- Suspension compatibility: When replacing springs, verify eye-to-eye length, width, and load rating to maintain proper ride height and load distribution on a 6×12 trailer.
- Compatibility with Lippert vs. Dexter: Some drums and hubs are branded to specific axle families. Cross-check your axle brand to avoid mismatches.
FAQ
- What does a 6×12 double axle trailer refer to?
It typically describes a trailer with two axles, each supporting a wheel arrangement that fits specific drum/hub configurations and bolt patterns, commonly used in mid-to-heavy-duty trailers.
- Do I need a full brake kit or just drums for my trailer?
It depends on your current setup. If both drums and brakes are worn, a full kit (drums, bearings, seals, and related hardware) can simplify replacement and ensure compatibility.
- How do I know which brake bolt pattern to choose?
Measure the drum or hub bolt circle (e.g., 6 on 5.5″, 8 on 6.5″) and confirm the axle rating to match the correct pattern and capacity.
- Are self-adjusting brakes better for a busy work trailer?
Yes. Self-adjusting brakes reduce manual maintenance and help maintain braking performance over time, which is beneficial for frequently used trailers.
- Can I mix parts from different brands on a single axle?
Mixing brands is not recommended unless the parts are verified to have identical measurements and compatibility with your axle system.
