DEEPDREAM 2 Sets Trailer Bearing Kit
The DEEPDREAM kit supports 3500 lb axles ranging from 1-1/16″ to 1-3/8″ with spindle #84 compatibility. It includes two sets of inner and outer bearings, corresponding races, two grease seals (171255TB), spindle nuts, washers, cotter pins, dust caps, and rubber plugs. This value-packed kit is designed to cover multiple service events, offering redundancy for routine maintenance or unexpected repairs. The included dust caps and rubber plugs help keep contaminants out while maintaining hub cleanliness during installs.
Key considerations:
- Compatiblity: Works across 1-3/8″ and 1-1/16″ axle dimensions; good for dual-repair scenarios.
- All-in-one kit: Includes most common ancillary parts for a straightforward install.
- Quality of seals: 171255TB grease seals provide a robust seal for standard marine environments.
iBroPrat 2 Sets 3500 LB Kit
The iBroPrat kit includes two complete sets designed for 1-1/16″ to 1-3/8″ axles and #84 spindles. The package lists two bearings and two races for each inner/outer set, plus two grease seals (171255TB), two dust caps (1.98″), two cotter pins, two spindle nuts, two washers, and two rubber plugs. An emphasis on cost-effective repairs is evident, with extras provided to cover recurring maintenance needs. The kit also notes the importance of including dust caps and spindle nuts for a complete rebuild.
Key considerations:
- Comprehensive inclusion: Caps, nuts, and washers reduce the need for separate purchases.
- Cost efficiency: Multiple parts in a single package lowers the per-repair cost.
- Seal sizing: Grease seals sized to fit the 1.719″ ID and 2.56″ OD of the L68149/L68111 families.
GREPSPUD 2 Sets Trailer Hub Kit
The GREPSPUD kit is designed for 3500 lb trailers with 1-1/16″ to 1-3/8″ tapered EZ-Lube spindles. It includes pre-lubricated bearings and grease seals for quick installation and immediate use. The kit is explicit about size verification before purchase to ensure proper fit, as the outer and inner bearing sizes are defined as L44649 and L68149 respectively. A notable strength is the pre-lubricated feature, which reduces installation effort and helps in initial startup after replacement.
Key considerations:
- Pre-lubrication: Reduces installation friction and initial break-in period.
- Size verification: Important to avoid misfit on non-standard spindles.
- EZ-Lube compatibility: Suited for common trailer hubs with a 5-bolt pattern on the outer edge.
Redants 2 Sets 2000lbs Hub Kit
The Redants kit is tailored for 2000 lb trailer axles with 1-1/16″ straight spindles. It arrives pre-installed with bearings and seals, enabling direct installation and immediate use. It emphasizes rugged, rust-proof construction and a black-coated hub surface for corrosion resistance, which is particularly relevant for marine environments. The kit includes essential components such as dust caps, cotter pins, and rubber plugs to seal the system against water and debris.
Key considerations:
- Pre-installed bearings: Quick installation and less downtime.
- Straight spindle compatibility: Not suitable for tapered spindles—verify axle type before purchase.
- Durability: Emphasis on rust resistance and long-term performance in coastal or humid conditions.
KABOBEARING 2 Set For 1″ Axles
The KABOBEARING kit offers two sets for 1″ 2,000 lb axles with L44643 and L44610 bearings. The package includes two 12192TB seals, two dust covers, and cotter pins. Bearings are listed as ABEC-3 level, manufactured from chrome steel for durability and smooth operation. This kit is particularly suitable for older or retrofit setups needing precise 1.0″ ID bearings and a 1.98″ OD seal.
Key considerations:
- Bearing clarity: Clearly differentiates inner and outer sizes (L44643 and L44610).
- ABEC-3 precision: Indicates reliable, smoother performance for trailer hubs.
- Compact kit: Suitable for smaller or lighter-duty trailer configurations.

Buying Guide: Key Purchase Considerations For Boat Trailer Bearings
- Spindle type and size: Confirm whether your trailer uses tapered or straight spindles and measure inner/outer bearing IDs and seals to ensure a correct fit.
- Axle capacity: Many kits target 3,500 lb trailers, but verify your axle’s weight rating and hub compatibility before purchasing.
- Seal material and lubrication: Grease seals must handle marine moisture and salt exposure; pre-lubricated seals can simplify installation but ensure suitability for your climate.
- Included components: Look for kits that provide caps, nuts, cotter pins, washers, and dust plugs to avoid multiple orders during replacement.
- Number of sets: If you own a multi-axle trailer, or anticipate future repairs, consider bulk options (2–4 sets) to reduce downtime.
- Build quality and corrosion resistance: Marine environments demand rust-resistant materials and coatings; chrome steel bearings and coated hub surfaces are advantageous.
- Warranty and vendor support: Check for product warranties and responsive support in case of part mismatch or questions during installation.
- Installation ease: Kits with pre-assembled or pre-lubed components speed up the process and reduce risk of improper lubrication during assembly.
- Compatibility notes: Some kits specify compatibility with EZ-Lube hubs or specific spindle angles; ensure alignment with your hub design.
- Maintenance plan: Pair bearing kits with a routine inspection schedule to check for play, heat, or noise, and to grease at recommended intervals.
These considerations help ensure you select a kit that not only fits your current trailer but also supports reliable performance through boating seasons. Matching the correct inner and outer bearing sizes, along with the right spindle type, reduces the risk of premature wear and helps maintain safe towing conditions.
