Question:
Hello, according to the label on my axle I need a hub face of 95 and a spring center of 81. I am only able to find a spring center of 80, no 81. Will the 95 hf with a spring center of 80 fit the 81? If not, do you have any axles that do match what Im looking for? Ive attached a picture of the label on my axle for reference. Thank you.

Hey Joseph,
You could use one of those axles, but you'll have to cut off the spring seats and have them welded back on in the correct spacings.
To get you back up and running, I have a few options for you. The solution directly from us is to get one of the Timbren Axle-less systems, which come in the following configurations:
- Spindles Only # ASR3500S05
- Idler Hubs # A35RS545
- Electric Brakes # A35RS545E
If you're wanting to stick with a standard axle setup, then I recommend checking out the linked installer locator to find a shop in your area that can help you custom order an axle with the exact specs you need.
