How NOT to lift a Truck or Jeep

What happens here

The presenter highlights two critical common mistakes during lift kit installation. The first is forgetting to install bump stop extensions before the coil spring, which necessitates re-doing previous work. The second, and more dangerous, mistake is prematurely disconnecting the lower control arms. For smaller lifts (e.g., 4-inch lifts), it is often unnecessary to disconnect these, and doing so risks the axle falling out of proper alignment, making reassembly difficult and potentially dangerous. For larger lifts (6-8 inches or more), it's essential to use appropriate heavy-duty jacks and ensure the axle is independently supported, completely free of the vehicle's suspension, to prevent uncontrolled movement or personal injury.

Goal: Understand and avoid critical mistakes during lift kit installation to ensure safety and efficiency.

Tools and materials

  • Heavy-Duty Floor Jacks — Providing independent support for the axle during larger lift installations, preventing it from tipping

common mistakes guys would be making besides what we've already covered getting this in here before you get the the uh coil spring installed? This is the biggest mistake. Guys will overlook this every single time without getting, you know, you get the coil spring together and you'll be like, "Oh crap, bump stop doesn't fit through the coil spring." The other mistake guys might make, you saw how we had to pull down on the axle on the other side. That's because these lower control arms are holding the axle. guys will loosen these lower control arms. These lower control arms are what's holding this axle from falling in your face. So, you take these bolts out, you take these lower control arms out, even though you're going to be replacing them, this axle is going to tip backwards and you're going to have a whole mess on your hands. So, don't disconnect this trying to get space. But what if you're putting like a six or an 8 in lift in or some monstrosity? When you go that big, you have to take a little bit extra precautions on stuff. So, if we were doing that kind of height, we would have our bigger jacks underneath supporting the axle by itself, free of the Jeep itself. It would just be an axle floating under here with some brake lines. If you know what you're doing, how long will this take? If you know what you're doing, you have all the proper tools. The internet will tell you 6 hours, more like 10. Okay. Um, if you're doing this in your driveway with some hand tools, a full weekend. And that's if you don't break anything or if nothing's rusty.
