How to Determine Which Extreme Cam Kit You Need Easily with 2 Measurements
We are proud to offer a wide range of high-quality Extreme Cam s-cam bushing kits for all of your trailer brake needs. Our Extreme Cam bushing kits are designed to provide exceptional durability and performance, ensuring that your trailer remains in optimal working condition.
We are committed to providing you with the necessary information to make an informed decision. If you are in need of an Extreme Cam bushing kit, the first step is to measure the diameter of your spider and the length of your S-cam.
1. Measure Your Spider Inner Diameter
To measure the diameter of your spider, place a digital caliper across the center of the spider where the S-cam shaft passes through. Record this measurement in millimeters or inches, depending on your preference.
This measurement will be used to determine the first two digits of the Extreme Cam part #. If your spider measures 1-7/8″, the first two digits of your part number will be 11. If your spider measures 2″, the first two digits of your part number will be 12. If your spider measures 2-1/8″, the first two digits of your part number will be 13.
For example:
C1311A-L = inner spider diameter of 2-1/8″
C1224A-L = inner spider diameter of 2″
C1126A-R = inner spider diameter of 1-7/8″
CXXYYA-L
2. Measure Your S-Cam Length
Next, measure the length of your S-cam. Start at the bottom of the S-head and measure all the way down to the last snap ring groove. Again, record this measurement in millimeters or inches.
The second measurement that you need to determine your Extreme Cam part number is the S-Cam Length. To determine your S-Cam Length, measure your s-cam lengthwise from the inside of the s-head to the snap-ring groove at the end, past the spline.
This approximate length will be used to determine the second two digits of the Extreme Cam part # (YY below):
CXXYYA-L
For example:
C1311A-L = s-cam length of 11-1/32″
C1224A-L = s-cam length of 24″ through 24-3/8″
C1126A-R = s-cam length of 26-1/4″ through 26-1/2″
Note that Extreme Cams are also offered for worn spiders. Review details on how to determine your part number if you have a Worn Spider or give our Customer Service team a call at (888) 844-7734.
