These are excellent. I bought 8 of them for the vehicle in the picture and they have worked perfectly. Clearly they can be used for many applications with very little adaptation needed. Have a great day.

See what our Experts say about this TruRyde Trailer Spindles

  • How to Determine Hub and Spindle Size
    The spindle dimensions are as follows: A is the mounting dimension, B is the seal dimension, C is the inner bearing surface, D is the outer bearing surface and E is the diameter of the threaded portion of the spindle for spindle nut selection. Say you need a spindle and hub for a wheel with 5 on 4-1/2 inch bolt pattern and an axle that is 3500 lbs. For a single axle trailer you can use two of either the item # TRU64FR, if your axle is round or item # TRU47FR if your axle is square. Then...

  • Replacement Spindle For Jet Ski Trailer With 2,700 lb Capacity
    Appreciate all that information, but unfortunately we do not have a 2,700 lb spindle, or one with those bearings and seal. The best I can offer is to go up to a 3,500 lb spindle, and you'd also need new hubs. What you can use is the following: - #84 Spindle for 3,500-lb Trailer Axles - 1-3/4" Diameter # TRU64FR - Trailer Idler Hub Assembly for 3,500-lb Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-35-G-K I realize this isn't exactly what you were looking for, but I did want to mention...

  • How to Choose Correct Replacement Trailer Spindle
    Definitely feel free to send in a photo of the damaged spindle, but photos can only help out so much. The best way to know we're getting you the correct spindle replacement is for you to measure the spots along the spindle where the bearings and seal are seated, as well as note the weight capacity of your trailer axle. Once we know all of this we can filter through our selection and find the best replacement option for you. For example, the #84 spindle # TRU64FR uses inner bearing # L68149,...

  • Availability Of 5-5 1/2 Inch Hub Assembly, Spindle, Bearings Rated For 1,750 lbs. Each
    I have the Dexter Trailer Hub Assembly - 3,500 lbs Axles - 5 on 5-1/2, # 84555UC1, which is rated at 1,750 lbs. each. The bearings, races, cap and seal included.

  • Trailer Hub To Spindle Combinations for 2000 Pound or 3500 Pound Axle
    The HUB KIT # 8-259-5UC1, uses a 1,000 pound spindle, item # TRU44FR. This setup is for a 2,000 pound axle. The #84 Spindle for 3,500-lb Trailer Axles - 1-3/4" Diameter, item # TRU64FR, is for a 3500 pound axle. If you need a hub and spindle for a 3,500 pound axle then you would use the # TRU64FR spindle and the Trailer Hub Assembly for 3,500 lbs Axles with 5 on 4-1/2 bolt pattern, item # 84545BX.

  • Recommended Trailer Idler Hub for a Trailer with 84 Spindles
    The threaded portion of the spindle isn't that important when picking out a replacement hub. That portion of the spindle is only for the castle nut, and since you have that already you would be fine. As long as the rest of the dimensions of your spindle match the # TRU64FR then the hub part # 84545BX would fit.

  • How Far Out will a Hub Face be on a #84 Trailer Spindle
    I can tell you roughly where the hub face will be on a #84 spindle but I would have to use # TRU74FR as an example. On this spindle from the brake mounting flange to the hub face it will be approximately 3 to 3-1/2 inches. Since spindle # TRU64FR does not have a mounting flange you would be looking at the distance from about an 1 back from the line between the raw steel and the machined steel on the stub to the hub face. These are the best guesstimates I can provide without having everything...

  • What Size are the Bearings in the Titan Disc Brake Kit # T4747200 and the Spindles That They Fit
    The bearings that are included in the Titan Disc Brake Kit, part # T4747200, are the # L44649 for the outer bearing and the # L68149 for the inner bearing. The # L44649 outer bearing has an inside diameter of 1.063, which is 1-1/16 inches and the # L68149 inner bearing has an inside diameter of 1.378, which is 1-3/8 inches. These dimensions match the dimensions on your spindle. The Titan Disc Brake kit will work on tandem axle trailers with 3,500-lb axles and a wheel size of 14 inch or...

  • Compatibility of Disc Brake Kits for Idler Hubs on Boat Trailer
    The Kodiak Disc Brake Kit # K2R35S is designed for 3500-lb-rated axles that have idler hubs and allows converting them from idler to disc brake operation. The bolt pattern determines whether they will fit on your idler hubs; and they will fit a #84 spindle like # TRU64FR. This system would brake too aggressively if installed on a 2100-lb GAWR axle. Brakes should always be selected based on the axle weight rating; this is true for disc or drum brakes. Typically a 2100-lb axle will have...

  • Which Trailer Spindles Fit Trailer Hub Assembly # 84555UC1
    I have three options that will fit Trailer Hub Assembly # 84555UC1, for 3,500 lbs. Part # TRU64FR is a standard 1-3/4-inch round spindle that measures 8-1/4" in overall length.

  • Spindle and Idler Hub Assembly for 3500 lb Round Trailer Axle
    The Trailer Idler Hub Assembly, # AKIHUB-655-35-K, with a 6 lug on 5-1/2 inch wheel bolt pattern will fit the TruRyde Spindle # TRU64FR. These parts are compatible for use on a 3500 lb round trailer axle. When installing these parts, I recommend the LubiMatic Deluxe Bearing Packer, # L70025, along with LubriMatic LMX "Red" Industrial Strength Grease, # L11390. For a grease gun, I'd suggest # L30200.

  • Looking for 5 on 4-3/4 Inch Bolt Pattern Idler Hub Compatible with L44649 Inner and Outer Bearings
    The L44649 bearing is compatible with a 1.062 inch (1-1/16 inch) spindle which is used on 2000, 2200, 2500 and 2700 lb axles. A 5 on 4-3/4 inch bolt pattern hub is found on hubs compatible with a 3500 lb axle, and uses different bearings (L68149 inner and L44649 outer), so we unfortunately don't offer a hub with that bolt pattern that's compatible with your current spindles. This leaves you with a few options. You could replace your existing axle with one that's compatible with the bearing...

  • Troubleshooting Hub and Spindle Not Fitting Together after Replacing Spindle on a Utility Trailer
    It sounds and looks to me like you have the wrong hub assembly for the spindle that is welded to the axle on your trailer. The photos you sent clearly show a 1-1/16 inch spindle similar to the BTR EZ Lube Spindle item # TRU44FR. This is a spindle for a 2,000 pound axle. The parts that you referenced are for a 3,500 pound axle and definitely will not work on a spindle designed for a 2,000 pound axle. In addition, the photo of the hub that you sent looks like a hub for a 3,500 pound axle,...

  • Do You Have a Replacement Wheel Hub For a Discontinued Harbor Freight Boat Trailer?
    Unfortunately Tim, I have no way to know for sure what size spindle you have on your discontinued Harbor Freight boat trailer. If you can provide me with the measurements off your spindle as seen in the image below I can see if we have a hub which will fit but as is most common with Harbor Freight trailers I have seen you are most likely going to need 2 new Spindles # TRU64FR and Hubs # AKIHUB-545-35-G-EZ-K.

  • Replacement Idler Hub Options For a 30 Year Old Homemade Trailer With 68149 & 12749 KOYO Bearings?
    I have a couple recommendations for you as your current spindle size is obsolete. First you can have 2 new Spindles # TRU64FR welded on your axle to use the current Hub # AKIHUB-545-35-EZ-K. The simplest option may be to use the CE Smith Trailer Axle w/ Idler Hubs # CE33201GA-HUB. This gives you an all new axle and hubs so you do not have to worry about welding the spindles on straight or the axle tube bending due to the age of the steel.

  • Recommended Idler Hubs and Electric Drum Hub and Brakes for Horse Trailer with 3,500lbs Axles
    It sounds like you have a 3,500lb axles on your horse trailer from your measurements. For 5 on 4-1/2 bolt pattern idler hubs I recommend the # AKIHUB-545-35-EZ-K. For the 5 on 4-1/2 bolt pattern electric brake hub I recommend the # AKHD-545-35-K. For self adjusting 10 inch brakes that will work with the # AKHD-545-35-K hub you will want (right) # AKEBRK-35R-SA and for (left) # AKEBRK-35L-SA.

  • Recommended Spindles, Hubs, Wheels and tires for 1200 lb Piece of Agricultural Equipment
    If a 2000 lb capacity per pair of spindles would work for you, I'd go with the # TRU94FR spindle along with the # AKIHUB-545-2-LFEZ-1K complete hub which includes bearings, races, the grease seal, the dust cap and lug nuts. The hubs are even pre-greased. The hubs are sold individually. For a compatible wheel/tire combo, use # TA53VR. This is a 205/75-15 bias-ply tire mounted on a white spoke 15 inch wheel with a 5 on 4-1/2 inch bolt pattern. If you're looking for something with a higher...
