This spindle can be used as a replacement spindle for a 5.2 – 6K axle or a 7K axle. The bearings that it will use are 25580 inner bearing, outer bearing as 15123 for 5.2K – 6K axle. And 25580 inner bearing and outer bearing 14125A for a 7k axle.

  • What Is The Diameter Of The #42 Spindle TRU39FR That Goes In Axle Tube?
    The #42 E-Z Lube 4" Drop Spindle w/ Flange for 5.2K to 7K Trailer Axles - 3" Diameter # TRU39FR you were looking at is designed to fit snugly into a # 42 axle, and the portion of the spindle that goes into the axle measures 2.45" so as long as that matches your axle this will not require any modification to your axle tube. I included a video of the # TRU39FR for you to take a look at.

  • Availability Of A #84 Spindle For A 3" Axle Tube
    We do carry the #84 spindle # TRU77FR which is designed to accept a 3" axle beam. The spindle itself has an overall length of 6-1/8". This is the only #84 spindle we have for a 3" tube. All of the others would be a #42 spindle like the # TRU39FR

  • Availability Of Replacement Spindle For 7000lb Dexter Trailer Axle Beam W/ 4" Drop 8327872
    I have another option for you but there is not a screw on spindle available for the # 8327872 you were looking at. To replace one of the spindles on the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles - 94" Long - 7,000 lbs # 8327872 you would need to have the #42 E-Z Lube 4" Drop Spindle w/ Flange for 5.2K to 7K Trailer Axles - 3" Diameter # TRU39FR welded on by an axle shop as it will need to be perfectly square to the axle and the other spindle. I included a video of the #...

  • Replacement 4" Drop Spindle For Dexter 7,000LB E-Z Lube Trailer Axle
    The #42 E-Z Lube 4" Drop Spindle w/ Flange for 5.2K to 7K Trailer Axles # TRU39FR is the same size as that used on the Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles # 8327860. Both will fit the same Dexter Trailer Hub and Drum Assembly # 42866UC3-EZ. It is important to have the replacement spindle welded by a professional in a jig to ensure it is straight and true.

  • Are There Electric Trailer Brakes To Replace Warner Brakes On a 1960's Trailer?
    Unfortunately Bill, we are not going to have any parts that will let you keep your current axles. You can either look at getting replacement axles which I can help you find or you can look at installing the more common #42 Spindle # TRU37FR or # TRU39FR on your axle. These would need to be welded in by a shop with an axle jig to ensure they go on perfectly straight. If you can let me know what width axle you have from hub face to hub face and spring center to spring center I can determine...

  • Parts Needed to Convert 2004 EZ Loader Boat Trailer to Disc Brakes
    To start you will want the Kodiak Disc Brake kit part # KOD69FR which is a Dacromet coated hub and rotor kit that fits your spindle. You will need to swap out the grease seals though to the # GS-2125DL since you have the slightly smaller spindle. Then you will lastly need to swap out the master cylinder of your Titan Model 10 drum actuator to the part # T4747100 and you'd be set.
