There are many parts associated with lowering and lifting flip kits and relocating your axle to the upper portion of your leaf spring. X2 Industries carries a wide variety of axle flip kits for many popular years, makes and models of trucks to make your lowering project quick and easy. When we say kit we mean it is 100% complete, so that you can get the job done without any hassle.
To understand how these kits work we will first take a look at each of the parts included within the kit.
The first part we look at is the C-Notch or some people call it a Frame Notch. This simple yet extremely necessary part allows your axle to travel further into the fame of the truck or SUV without sacrificing stability and strength. This notch requires the installer to trim a section of the frame out for the extra travel and then reinforces this area with a strong custom fabricated bracket which installs in the trimmed area to ensure your frames integrity is not compromised by this opening. Below are some pictures of these frame notches.
Next we will discuss the leaf spring mount which is referred to as the perch. This piece of hardware is used to stabilize your axle and support an alternate position to mount your axle to the leaf spring assembly. This part actually creates the platform for your axle flip. Please refer to the diagram below which will give you a better idea as to how this works. (NOTE: This spring perch hardware in most cases will need trimmed to fit your axle and correct your axle pinion angle. Be sure to measure this out carefully and only trim if you are absolutely confident in the fitment, as if you trim this too far then there will be axle twist and play which will be felt during acceleration and deceleration.)
Installing the perch for the flip kit requires trimming the tabs that hold the axle in place with the factory perch to ensure correct pinion angle and a sturdy installation.
Once all parts have been measured, trimmed and ready for installation use the illustration above to assemble your new flip kit hardware together and tighten everything down using the larger u-bolt hardware that will be included with your kit. NOTE: In some cases our flip kits will include lowering shackles with your kit to ensure the specified drop for your specific application. Installation of these drop shackles are fairly quick and are simply the reverse of the removal of your current OEM shackles.
