See what our Experts say about this TruRyde Trailer Spindles
- What Material are Trailer Spindles Made ofTruRyde spindles, like # TRU57FR are made of automotive quality high strength steel.
view full answer... - Compatibility of Redline Replacement Axle Spindles with Dexter HubsTruRyde Spindles are indeed compatible with Dexter hubs, if the spindle is matched properly with the bearings your hub uses. To find the correct spindle, match the inside diameter of your inner bearing, outer bearing and grease seal to the dimensions of the bearing surface of the spindle, as shown in the photo I provided. You'll also need to match the weight capacity of the spindle with that of the axle.

- What Size Spindle is Needed for a M/H trailerThe axle spindle you need to order will depend on the weight capacity of your trailer and on the type of spindle (see link) already being used, if you only need to replace one spindle. To figure out which spindle is correct you can use the bearing part numbers, both inner and outer, and the shape and length of the spindle stub on your trailer. The bearing numbers will let you cross reference the correct spindle measurements for your hub. The axle stub shape and length will allow you to...
view full answer... - What Steel Is The TruRyde 42 Spindle # TRU57FR Made From?Yes, the #42 Spindle # TRU57FR is made from SAE 1045 hot rolled steel bar stock.
view full answer... - Replacement Spindle for Premco Tandem Axle TrailerOur main page for trailer spindles is linked for you. Since your tandem axle trailer is rated for 9500-lbs it uses either 5000-lb or 5200-lb axles. For a 5K axle we offer # TRU57FR which uses a grease seal with an inner diameter (ID) of 2.24-inches, an inner bearing ID of 1.74-inches and an outer bearing ID of 1.25-inches. For a 5200-lb axle we have E-Z Lube spindle # TRU37FR which has the same seal and bearing surface dimensions. Please refer to the items' linked pages for a diagram...
view full answer... - Capacity of Trailer Axle Spindles # TRU57FR and # TRU34FRThe only capacities we have for the two spindles you mentioned is the capacity of them if they are used as they are intended on a trailer axle. The part # TRU34FR is for a 3,000 lb axle so it has a 1,500 lb capacity and the # TRU57FR is intended for a 5,000 lb axle so it has a 2,500 lb capacity.
view full answer... - Spindle With Same Dimensions as TRU37FR That Does not Have EZ Lube or FlangeThere is the same spindle as # TRU37FR but is not EZ Lube and does not have a brake flange. What you are seeking is spindle # TRU57FR which is otherwise the same; I've added a link to a video review of this spindle for you to take a look at.

- Replacement Spindle for 7,000 lbs AxleWe have the #42 E-Z Lube Spindle w/ Flange for 5.2K to 7K Trailer Axles - 2-1/4" Diameter # TRU37FR and the #42 Spindle for 5,200-lb to 7,000-lb Trailer Axles - 2-1/4" Diameter # TRU57FR which are both compatible with 7,000 lb axles. Both will measure 4 inches from the grease seal position to the threads. You can see this in the attached video at the 1:42 second mark. The difference between these is the zerk fitting and the brake flange. The spindle dimensions will be identical.
view full answer... - What Spindles Should be Used on Dexter 7k Trailer AxleYes, the number 42 spindle is the standard for Dexter 7k axles like what you have. For that we have the part # TRU57FR which does not have a brake flange or we have the part # TRU37FR which does have the brake flange.
view full answer... - Welding #84 Spindles # TRU84FR and # TRU57FR for Utility Trailer with 2-3/8 inch O.D. PipeYou have a 2-3/8 inch O.D. pipe so you might want to look at #84 Spindle, # TRU84FR, which has a 2 inch O.D. at the weld point and has a 1750 lb. capacity, so two spindles will give that axle 3,500 lb capacity. The #42 Spindle, TRU57FR which has a 2.25 inch O.D. at the weld point and is rated for 5,200 lbs to 7,000 lbs axles. The total capacities of the spindles are only valid if installed correctly and the axles are not broken or damaged in any way. The TruRyde #84 Spindle, # TRU47FR,...
view full answer... - Replacement Axle Spindle With 2.25 Diameter SpindleHere is a list of the Agricultural Spindles we currently carry. Spindle # TRU34FR Spindle # TRU54FR Spindle # TRU67FR We also have the #42 Spindle # TRU57FR which has the 2.25" that may be what you are needing. This is a very common size that may have been used in a Agricultural application.
view full answer... - Which Spindle is Used with Trailer Hub Assembly, Part # 42865UC1There are two spindle options for the Trailer Hub Assembly, part # 42865-KIT. The spindle used would depend on the capacity of your axle. For a 5000 pound axle, use part # TRU57FR. For a 5200 pound axle, you would use part # TRU37FR. The TRU37FR is an EZ lube spindle with the zerk fitting for adding grease to the bearing assemblies.
view full answer... - Will TruRyde Spindle TRU57FR Fit Dexter Trailer Hub Assembly 42865-KITThe TruRyde #42 Spindle # TRU57FR is compatible with the Dexter Trailer Hub Assembly # 42865-KIT. Since the hub uses bearings 25580 and 14125A, whose inner diameters match up to the spindle dimensions, the hub will work on the spindle. Spindles need to be professionally welded on perfectly straight and concentric to ensure you do not have issues with trailer tracking or uneven tire wear.
view full answer... - How to Determine Correct Replacement Spindle Based on MeasurementsI can tell you how to determine the correct spindle based on your measurements, and what you will need is a digital caliper such as # 301-17068, though the first thing you need to know is the weight rating of your trailer axle. From there, what you need to do is measure your spindle to the thousandths of an inch where the bearings and grease seal ride, along with the length and diameter of your stub. For example, the accompanying diagram shows the measurements of the #42 Spindle for 5,200...

- Which Spindle Will Fit 6 on 6 Dexter Hub Part 42660UC1The correct spindle for Dexter hub, part # 42660UC1, is spindle part # TRU57FR or EZ Lube spindle part # TRU37FR. There are other 6 on 6 hubs that you could use if you want heavier spindles. How much weight are you wanting each axle to hold? How many axles?
view full answer... - What Bearing Kit Fits the Trailer Spindle part TRU57FRFor a bearing kit that fits the #42 spindle part # TRU57FR that you referenced you would want the part # BK3-300.

view full answer... - Replacement 7,000LB Trailer Axle SpindleI have been unable to locate a spindle that meets the exact specifications that you have on your current spindle. The #42 Spindle # TRU57FR will be the closest that I can find to matching your current spindle. It is 2.25" diameter, rated for 7,000lbs. Overall length is only 11", has a 1.75" inner bearing, 1.25" outer bearing and 1" nut. The spindle includes a new washer, castle nut and cotter pin.

view full answer... - Which Spindle Do I Need To Use with 8 on 6-1/2 Drum and Hub Assembly part # 8-219-4UC3I cross referenced the bearings that Trailer Hub & Drum Assembly - 5,200, 6,000, 7,000 lbs. Axles - 8 on 6-1/2, PART # 8-219-4UC3, uses to determine which spindle you will need. The correct spindle you will need is EZ Lube Spindle, part # TRU37FR.
view full answer... - Number 42 Spindle RecommendationWe do have a Dexter number 42 spindle. For a standard spindle you would want the part # TRU57FR. For the EZ lube version you would want the part # TRU37FR. This comes with a brake mounting flange. The seal inner diameter needed for this would be 2.24. The bearing dimensions you referenced are correct.
view full answer... - Recommended Spindle For # 8-174-5UC3 Trailer Hub And Drum AssemblyThe spindle that would work with the hub # 8-174-5UC3 you mentioned is the TruRyde Spindle, part # TRU57FR. This spindle includes the washer, castle nut, and pin. This has a 2,500 lb capacity. I have attached a product review video for this spindle you can check out.

These spindles are compatible with a 5200, 6000 or 7000 lb capacity axle, the axle capacity will depend on the bearing set used.
