#1 · Best Overall

1. Lippert Trailer Bearing Kit

• Weight: 1.75 lb

Best for: Lippert 5,200-Lb Hub Service.

Why it ranks #1: Specified for 5,200-lb axle hubs, with a 2.25-inch double-lip seal plus listed cotter-pin and tang-washer dimensions.

A 2.25-inch inner-diameter double-lip grease seal distinguishes Lippert’s replacement kit for 5,200-lb axle hubs. Its listed inner and outer bearing cones, races, cotter pin, and tang spindle washer offer key service parts together, while the seal specification gives buyers a concrete dimension to compare with their setup.

Lippert lists a 2.25-inch inner-diameter double-lip grease seal, which makes seal sizing an explicit part of the fit check and supports the kit’s stated sealing focus. Inner and outer bearing cones and races provide the central bearing-service components, while the 1.75-inch cotter pin and 1.5-inch tang spindle washer add specified hardware for the assembly. The product is identified for 5,200-lb axle hubs, and the listing emphasizes straightforward installation and servicing.

Skip it if you need two seal sizes in one package; GREPSPUD’s D42 kit includes 2.125- and 2.25-inch inner-diameter seals.

A focused option for a buyer replacing parts on a 5,200-lb axle hub who can use the specified 2.25-inch double-lip seal. Confirm that seal dimension and hardware details suit the assembly being serviced.

2. GREPSPUD D42 Bearing Kit

• Material Type: Alloy Steel, Rubber
• Compatible Lubricant: Grease

Best for: Two-Size Seal Coverage.

Why it ranks #2: Fits 5,200–6,000-lb tapered D42 axles and includes two grease-seal sizes to address differing D42 spindle requirements.

Two grease-seal sizes in one four-set kit address a specific D42 spindle complication: GREPSPUD includes 2.125- and 2.25-inch inner-diameter seals. That gives buyers options when matching the seal to the spindle, alongside named 25580 and 15123 bearings for tapered 5,200–6,000 lb axles.

The listing specifies tapered 1.25- to 1.75-inch axles, a D42 spindle, and a 5,200–6,000 lb rating, making the fit boundaries clear; it explicitly excludes straight spindles. Named 25580 and 15123 bearing models provide another compatibility checkpoint. Including both 2.125- and 2.25-inch seal inner diameters can help address the two seal sizes noted for D42 spindles. Bearings, races, seals, nuts, washers, cotter pins, dust caps, and rubber plugs are listed.

Skip it if you have a straight spindle or need a stated 5,200–7,000 lb range; MCCKLE lists that broader capacity for D42 applications.

Choose this kit when servicing tapered D42 axles in the stated 5,200–6,000 lb range and the two seal sizes are useful. Its straight-spindle exclusion makes spindle type an essential fit check.

3. LUXTRKSTO D42 Bearing Kit

• Material Type: Carbon Steel, Rubber
• Compatible Lubricant: Grease
• Weight: 4.28 kg

Best for: D42 Tapered-Axle Kits.

Why it ranks #3: Targets 5,200–6,000-lb tapered D42 axles, specifies bearing numbers 25580 and 15123, and includes two seal sizes.

Two grease-seal inner diameters—2.125 and 2.25 inches—make LUXTRKSTO’s four-set kit useful when matching seals for D42 spindles. It specifies 25580 and 15123 bearings for 5,200–6,000 lb tapered axles, and explicitly excludes straight spindles.

The tapered-axle requirement, 1.25- to 1.75-inch range, and D42 spindle reference create clear fit boundaries; the listing also says not to use it on straight spindles. Named 25580 and 15123 bearing models support a separate component check. Including both stated seal sizes can help with D42 spindle variations, while the four-set package lists bearings, seals, axle nuts, washers, cotter pins, dust caps, and rubber plugs for related service tasks.

Skip it if you have a straight spindle or need a listed 5,200–7,000 lb capacity; Ruikarhop specifies that broader D42 range.

Choose this kit for four-set service on tapered D42 axles within the stated 5,200–6,000 lb range, especially when both seal sizes are useful. Its straight-spindle exclusion and bearing-model requirements define the fit.

Best for: Two Bearing-Model Coverage.

Why it ranks #4: Covers 5,200–6,000-lb tandem axles and lists bearings, races, two seal types, dust caps, plugs, nuts, pins, and washers.

Two named bearing pairs—25580/25520 and LM67048/LM67010—set this Racewill kit apart for buyers matching existing hub components. Four sets cover tandem axles rated 5,200–6,000 lb, and the package lists both 2.125- and 2.25-inch grease-seal inner diameters.

The 25580 inner bearing and 25520 race pair, together with LM67048 outer bearings and LM67010 races, give buyers specific model references for checking hub compatibility. Racewill lists a 1.25- to 1.75-inch tandem-axle range and 5,200–6,000 lb capacity. Two seal sizes, 10-36 and 10-10, are included alongside caps, plugs, nuts, cotter pins, and washers. Four complete sets make it useful for multi-hub servicing or keeping replacement components ready.

Skip it if you need a stated 6,000–7,000 lb application; Ruikarhop’s four-set kit lists a 5,200–7,000 lb range for D42 spindles.

This Racewill set fits buyers matching its named bearing and race models for 5,200–6,000 lb tandem axles. Its two seal types and four hardware sets help with planned multi-hub service, within that stated capacity range.

• Weight: 8.5 lb

Best for: D42 Tandem Axle Spares.

Why it ranks #5: Fits 5,200–7,000-lb tandem axles for D42 spindles and includes extra dust caps, rubber plugs, spindle nuts, shims, and washers.

Four complete sets cover tandem axles rated 5,200–7,000 lb, giving owners multiple bearing-service sets plus a reserve. Racewill specifies 1.25- to 1.75-inch axles and D42 spindles, while extra dust caps, rubber plugs, spindle nuts, shims, and washers add useful replacement hardware to the package.

The stated D42 fit and 5,200–7,000 lb range help narrow compatibility for the specified tandem-axle setup; the listing also calls out a 1.25- to 1.75-inch axle range. Extra caps, plugs, nuts, shims, and washers can keep related replacement pieces together during service, while four sets provide spares beyond a single repair. Alloy-steel construction and grease lubrication are specified. The listing identifies inner bearing cones and races among the included components.

Skip it if you need a stated 25580/15123 bearing combination; GREPSPUD’s four-set kit names those models and two seal sizes.

A practical choice for owners servicing D42 tandem axles in the stated 5,200–7,000 lb range who value extra hardware and reserve sets. Check that the bearing models and axle details match your hub before ordering.

6. Ruikarhop D42 Bearing Kit

• Material Type: Stainless Steel
• Compatible Lubricant: Grease
• Weight: 10.3 lb

Best for: Higher-Capacity D42 Service.

Why it ranks #6: Lists 25580 inner and 14125A outer bearings for 5,200–7,000-lb D42 axles, along with races, seals, and hardware.

A 5,200–7,000 lb capacity range gives Ruikarhop’s four-set D42 kit a broader stated application than kits capped at 6,000 lb. The package lists 25580 inner and 14125A outer bearings, plus 22333TB seals and related hardware, giving buyers concrete component references for hub service.

Ruikarhop specifies 1.25- to 1.75-inch tandem axles and D42 spindles, alongside a 5,200–7,000 lb rating. Those details help narrow fit checks, while the listed 25580 inner and 14125A outer bearings and their races identify the bearing arrangement. Eight 22333TB grease seals, cotter pins, caps, plugs, spindle nuts, and washers are included. The description also characterizes the chrome-steel bearings as quiet-running and durable.

Skip it if you need two seal inner-diameter options in one package; OZISENS lists both 2.125- and 2.25-inch seals for D42 spindles.

This kit suits D42 tandem-axle owners whose application falls within its 5,200–7,000 lb range and matches the listed bearing models. Its single specified seal type is a relevant consideration when checking hub fit.

7. MCCKLE 25580 14125A Kit

• Material Type: Alloy Steel
• Compatible Lubricant: Grease

Best for: Boat-Trailer D42 Applications.

Why it ranks #7: Its verified details specify boat and utility trailer use, tandem axles rated 5,200–7,000 lb, and #D42 spindles.

Corrosion-resistant grease seals are the notable material detail for this MCCKLE boat-trailer kit, whose bearings and races are alloy steel. The verified application covers tandem axles rated 5,200–7,000 lb with #D42 spindles, and the package contains four trailer wheel hub bearing kits.

The stated boat- and utility-trailer use, tandem-axle rating, and #D42 spindle reference give buyers a defined application to compare against their hub setup. Alloy-steel bearings and races provide the specified bearing material, while corrosion-resistant seal coating is relevant for trailer use around water. Four kits support service across multiple hubs or keeping spares available. The listing confirms grease compatibility but does not enumerate individual bearing models or seal dimensions.

Skip it if you require named 25580 and 15123 bearings plus two seal sizes; GREPSPUD lists both details for its four-set D42 kit.

A relevant pick for boat-trailer owners with tandem axles rated 5,200–7,000 lb and #D42 spindles, especially where corrosion-resistant seal coating matters. Check component dimensions if your service depends on exact models.

#8

8. OZISENS 25580 15123 Kit

• Compatible Lubricant: Grease

Best for: Two Seal Sizes Included.

Why it ranks #8: Lists 25580 and 15123 bearings and two seal sizes, but its title says 5,200–6,000 lb while the fitment text says 7,000 lb.

OZISENS includes both 2.125- and 2.25-inch inner-diameter grease seals, addressing the different seal sizes described for D42 spindles. The four-set kit also names 25580 and 15123 bearings and covers tapered 1.25- to 1.75-inch axles, with straight spindles explicitly excluded.

The two seal diameters can help match the kit to either of the stated D42 spindle seal sizes, while 25580 and 15123 bearing references support a model check before installation. OZISENS specifies tapered axles from 1.25 to 1.75 inches and excludes straight spindles. Its listed package includes four sets with bearings, grease seals, pins, caps, plugs, spindle nuts, and washers, consolidating named service components for hub work.

Skip it if you have a straight spindle or need a separately stated 5,200–6,000 lb limit; GREPSPUD explicitly lists that rating for its D42 kit.

Consider this kit for D42 tapered-axle service when both listed seal sizes and four sets suit the job. The stated axle dimensions and straight-spindle exclusion are important boundaries to check against your setup.

9. DEEPDREAM D42 Bearing Kit

• Material Type: Alloy Steel
• Compatible Lubricant: Grease

Best for: Two-Set D42 Maintenance.

Why it ranks #9: Covers 5,200–6,000-lb D42 axles and lists 25580 and 14125A bearings, but supplies two sets rather than four.

Two bearing-service sets keep DEEPDREAM’s package focused on smaller replacement jobs rather than a four-set stock-up. It lists 25580 inner and 14125A outer bearings for D42 tandem axles, along with 2.125- and 2.25-inch grease-seal inner diameters for seal matching.

The stated 1.25- to 1.75-inch tandem-axle range and D42 spindle reference help define the intended fit, while the listing gives a 5,200–6,000 lb rating. Named 25580 and 14125A bearings and their races provide model references for compatibility checks. Two sets suit a limited service requirement, and the included seal options cover 2.125- and 2.25-inch inner diameters. Caps, plugs, nuts, cotter pins, and washers are also listed.

Skip it if you need four service sets in one package; Racewill’s 25580/25520 and LM67048/LM67010 kit includes four for 5,200–6,000 lb axles.

This package suits a buyer handling a limited D42 tandem-axle service and needing the listed bearing models with two seal sizes. Its two-set quantity is the key boundary for multi-hub work or stocking spares.

#10

10. iBroPrat 25580 15123 Kit

• Material Type: Alloy Steel
• Compatible Lubricant: Grease

Best for: Four-Set Bearing Replacements.

Why it ranks #10: The title identifies 5,200–6,000-lb use and bearing numbers 25580 and 15123, but the supplied details offer little fitment or component information.

Four sets of 5200–6000 lb boat-trailer axle bearing kits are the defining feature here, giving buyers multiple service sets in one purchase. iBroPrat identifies the 25580 and 15123 bearing combination in the title and specifies alloy steel with grease lubrication for this kit.

The title names 25580 and 15123 bearings and a 5,200–6,000 lb boat-trailer axle application, so buyers can compare those details with their existing hub parts before service. Four sets make the package relevant when several hubs need attention or when keeping spare kits on hand. Alloy-steel material and grease compatibility are specified. The supplied specifications identify the included components as four bearing kits, without itemizing the races, seals, or other service hardware.

Skip it if you need individually specified seals and spindle hardware; GREPSPUD’s four-set kit lists both seal sizes and installation components.

This suits buyers seeking four kits for the stated 5,200–6,000 lb boat-trailer application and matching the named bearing models. Review the included-component detail carefully if your service requires separately enumerated seals or hardware.
