FAQ - Leaf Springs
Are Kilen leaf springs supplied with bushes?
Yes, Kilen leaf springs are fully bushed, using rubber bushes for lighter vehicles & rubber to metal bonded bushes for heavier vehicles.
What is the meaning of build 2+1, 3+2, 4+1, etc when describing leaf springs?
This describes the number of leaves in a particular leaf spring. Occasionally, some multi-leaf springs are produced with auxiliary (helper) springs, to stop the spring becoming inverted during load. Where an application is listed as having a build as 3+1, the +1 refers to the number of auxiliary springs.
Do Kilen offer replacement U-Bolts along with leaf springs?
Yes, Kilen offer a universal U-Bolt range covering the majority of applications, supplied complete with nuts.
Do I need to replace the U-Bolts when I replace a leaf spring?
Yes, we recommend replacing the U-Bolts with the leaf spring to ensure correct fitment.
The U-Bolts I have received are too long
As the Kilen U-Bolt range is universal, covering many applications, some are supplied longer than they need to be. They should be cut to the correct length for application during installation.
