These 5-lug hubs are designed for straight spindles up to 2,000 pounds. They support both 1″ and 1-1/16″ straight spindles (not tapered) and come with the appropriate bearings for each shaft size (L44643 for 1″ and L44649 for 1-1/16″). The kit also includes grease seals (two 1.25″ ID and two 1.5″ ID) to ensure immediate compatibility and simple installation. The packaging is multi-layered to protect parts during transit, reducing the risk of surface damage or contamination that can lead to premature wear. This kit is suitable for common 2,000-pound straight-spindle trailer axles and is a practical, budget-friendly option for anglers and boaters who require reliable wheel hubs.
GREPSPUD 2Sets Trailer Hub Kits 5 on 4.5″ (3500 lbs)
GREPSPUD offers a 3,500-pound-rated hub kit designed for tapered spindles (1-1/16″ to 1-3/8″). It’s not compatible with straight spindles, so verify spindle type before ordering. The kit includes 2 sets of hubs with outer and inner bearings (L44649 and L68149), dust caps, seals, lug nuts, and mounting hardware. Extra dust caps and rubber plugs are included for contingency parts, which is advantageous for routine maintenance and field servicing. The packaging emphasizes protection during shipping, providing a compact, organized solution to store the hubs and hardware when not in use. This kit is well-suited for larger-trailer axles and compatibility with popular brands using tapered spindles.
2 Sets 3500Lbs Trailer Hub Kit 5 Bolt 4.5″ (Saree)
This 3,500-pound kit targets tapered spindles (not for straight). It supports 1-1/16″ to 1-3/8″ axle sizes, uses 5×4.5″ bolt pattern, and includes L44649 outer bearings and L68149 inner bearings. The kit’s anti-collision packaging mirrors the standard used across these offerings, with an inner double-box setup to reduce damage and simplify storage. If your trailer uses a tapered spindle, this kit is a robust choice that aligns with major manufacturers such as Dexter, Al-Ko, Lippert, and Quality. The kit’s compatibility with common brands helps ensure a straightforward upgrade or replacement for aging hubs.

Bearings included are L44643 for 1″ axles and L44649 for 1-1/16″ axles, with grease seals sized at 1.25″ and 1.5″ inner diameters to suit common straight-spindle assemblies. The packaging emphasizes protection during shipping and storage, which can be a practical feature for boat trailers that are stored in garages or sheds. Its compatibility with straight spindles makes it a versatile option for many bass boats and small to mid-sized trailers that use standard straight spindles and 5×4.5″ hubs.

Buying Guide: Key Considerations for Boat Trailer Hub Kits
- Spindle compatibility: Determine whether your trailer uses straight or tapered spindles. Straight spindles typically align with L44643/L44649 bearings, while tapered spindles use different inner/outer bearing combinations (e.g., L68149). Mismatching spindles and bearings can cause seizing, heat buildup, or premature wear.
- Weight rating and bolt pattern: Ensure the hub kit’s weight rating (2,000 vs 3,500 lbs) matches or exceeds your axle rating. The standard 5×4.5″ bolt pattern is common, but verify your existing hubs or drum compatibility.
- Bearing and seal configuration: Pre-installed or packaged bearings and seals should match your spindle diameter. Confirm inner/outer bearing sizes to prevent incorrect installation and reduce service time.
- Lubrication: Prelubricated bearings or grease seals help reduce maintenance. If not prelubed, select kits that come with adequate lubrication or plan to apply grease during installation.
- Packaging and parts quantity: Anti-collision packaging reduces transit damage. Extra seals and dust caps provide backup parts for field maintenance or replacements.
- Brand and compatibility: Popular brands (Dexter, Al-Ko, Lippert, Quality) are often referenced in hub descriptions. While not all kits fit every brand, many are designed for compatibility with major manufacturers’ spindle types.
- Installation considerations: Some kits require specific spindle measurements (A and D bolt-pattern tolerances) to ensure a proper fit. If you’re unsure, measure your current hubs or consult the trailer’s axle manufacturer.
- Maintenance and longevity: Look for cast iron construction, heat transfer performance, and overall rigidity to ensure longer service life under typical boat-trailer conditions, including road use and salt exposure.
