The hubs you need will be based on the spindle size and bearings used. This will help your hub to be rated for weights related to the capacity of your axle. I've attached an article to assist, but you will need to pull one of your current hubs and look for the bearing numbers printed on the face of the inner and outer bearing of one of your hubs. If you cannot get these bearing numbers, then you will need to use a digital caliper like # PTW80157 to measure your spindles at the bearing locations. I've attached a photo to assist as well as a video.

I've also attached an article to help you determine the bolt pattern of your hubs as there are 4 options for 5 lug hubs. Let me know what you find and I'll be happy to help get you the correct hubs for your axle.

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…

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

The torque requirements for leaf spring u-bolts depend on the diameter of the u-bolts that are being used. If the gross weight of your tandem axle trailer is 7,000 lbs, then you likely have two 3,500 lb axles. Typically 1/2 inch diameter u-bolts are…

When replacing shackle straps they should be the same length as the ones that were previously on your tandem axle trailer; replacing them with longer straps will result in additional play in your trailer suspension which could lead to additional wear…
