The Trailer Axle w/ Electric Brakes # e45SR is the closest axle we have that meets the criteria that you gave me. This axle is 6,000lbs with a 4" drop. It has a spring center to spring center measurement of 74" and hub face to hub face of 89". It includes electric brakes and hubs with a 6 on 5-1/2" bolt pattern. The axle does include easy lube spindles that make greasing your bearings much easier.

If this will not work please let me know your hub face dimension and wheel bolt pattern so I can find you a different axle.

Be sure to use a new U-Bolt Kit # APUBR-8 as the current U-bolts are likely corroded and should not be reused.

I recommend looking at the Goodyear Endurance ST225/75R15 Radial Tire w/ 15" Silver Modular Wheel # LH33FR. This wheel matches the 6 on 5-1/2" bolt pattern of the new axle. The Goodyear Endurance tire gives you the ability to adjust the air pressure in the tire to best work with the actual load of your trailer. The tire is a load range E with a maximum capacity of 2,830lbs at 80psi. The air pressure can be lowered to as much as 25psi which will support 1430lbs per tire. This will allow for you to not have an overly bouncy trailer from tires that are rated much higher than the weight of the trailer. I have included the tire pressure chart from Goodyear on the allowable tire pressures and load capability ratings. Otherwise you will need a wheel with a 6 on 5-1/2" lug pattern that is between 14-1/2" and 16-1/2" in diameter that will fit 1/2" lugs. Your tire should size must fit within the fender of your trailer and weight capacity must reflect the maximum weight that your trailer is capable of towing. Do remember that just because you install a 6,000lb axle the trailer frame and springs may not be able to support the additional weight if you had a lower rated axle.

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
