Simply put a flip kit moves the axle from beneath the leaf spring to on top of the leaf spring. When you place your axle on top of the leaf springs there are two very important things to consider. No. 1 you must move the rear axle back towards the rear of the truck, away from the transmission, around ¾ of an inch. This is done because your drive shaft actually becomes longer when you “flip” your axle. You’ll notice the splined slip joint in the front of your drive shaft. It’s there to allow the drive shaft to move towards and away from the transmission as the suspension cycles up and down. If you were to support your truck by placing jack stands under the frame (both sides) in the rear. Then, with a floor jack supporting the rear end, remove the lower shock bolts and let the rear end down with the floor jack and look at the splined slip joint, you will see a fully extended slip joint. Now slowly jack the rear end up with the floor jack and watch the slip joint contract. If you could jack the rear end up to the point where it was level with the transmission the splines might completely disappear and the drive shaft would be forced into the transmission. This is not a good thing and why you need to move the axle back away from the transmission when you install a “flip kit”. The axle locator brackets accomplish this, generally a “U” shaped piece that sets on the leaf spring, over the center bolt. There is a hole in the factory axle locator which is centered, and you will see that the hole in the axle locator from the flip kit is offset. That is how the flip kit moves the axle back away from the transmission. It is very important to make sure you install the axle locator bracket correctly with the offset hole over the leaf spring center bolt spacing the axle to the rear. Now the second consideration when installing a “flip kit” is pinion angle. The typical drop you can expect from a flip kit is in the 5” to 8” range, depending on the thickness of your leaf spring pack. And while the rear of a pick up truck is designed to operate in a wide range of ride heights (empty to overloaded) it is still necessary to establish an optimal static pinion angle. Axle locating brackets in most flip kits have a built in angle, by having unequal length legs in the “U”. This works pretty good most of the time, but not all trucks are created equal and often you need to adjust the pinion to get rid of a pesky vibration. You can buy pinion “shim kits” that come in 2, 4, and 6 degree packages that need to be installed between your axle locator bracket and the leaf spring. Better that that, DJM makes their flip kits with adjustable axle locator brackets. You have the ability to rotate your axle to the proper angle and then lock it in place. This is the best way to deal with pinion angle. Oh, one more thing about vibrations, if you have a two piece drive shaft and you’re having very low speed vibrations it is almost always caused by the carrier bearing. The bearing where the short front drive shaft and the longer back drive shaft connect. Typically raising this “carrier bearing” up towards the bottom of the bed between ½” to 1” will rid you of this inconvenience. There are kits available for this condition also.  Product information updated on 2024-03-24. This product can ship by Small Parcel
