How do I know which springs to replace?
If I am replacing Reformer springs, how do I know if I need a Spring Holder?
We advise that springs be replaced every two years on any spring equipment to maintain your warranty and ensure optimal performance of your equipment. For more tips on equipment and maintenance care, download our Large Equipment Inspection & Maintenance Schedule for recommended guidelines and a full checklist.
I’m not sure what year my Reformer was purchased. Do I need a new Spring Holder?
Spring Holder Replacement Kits will be necessary if you purchased V2 Max®, Pro or SPX® Series Reformer before December 2011 and have not replaced your spring holder yet. If you purchased your Reformer after December 2011, you do not need to upgrade your spring holder.
Why do I need to provide you with the serial number for my equipment?
If you’re unsure when you purchased your Reformer, you can easily tell by looking at the Spring Holder on your Reformer.
Does your Reformer have…
Molded Spring Holder
No, an upgrade kit is not required
If you’re still unsure, send us a picture of your Reformer Spring Holder and we’ll let you know if your machine requires a Spring Holder Upgrade.

How do I find the serial number of my equipment?
Our equipment is serialized for quality control. Tracking the date you replace your springs also allows us to keep you informed of when it’s time to replace your springs to keep your equipment and its warranty in good standing.
After your spring purchase, we will contact you to ensure that we have correctly documented the equipment for which you are replacing the springs.

You can easily find the serial number by referring to your Owner’s Manual that you received with your equipment, or by locating it on the equipment. Please refer to the images below for specific locations of the serial number by equipment.
