Installing A New Frame On Your Jeep? Here's A Few Things To Know.

Do you have an old Jeep that needs a new frame? Let's go over all the things you need to know before tackling the job. A frame replacement is a big project, so it always pays to know as much as possible before rolling up your sleeves and diving in.

Are Jeep Frames Interchangeable?

The first thing most Jeep owners ask is whether Jeep frames are interchangeable. If you found a great deal on a Jeep frame that isn't built just for your Jeep model, you may be wondering if it'll fit your Jeep perfectly.

The answer depends on what model you have. The frame on your model may not be interchangeable with any other Jeep model, or it's interchangeable with a limited number of models. Here's a list of Jeep models with frames that can be swapped with each other:

  • All 1987-1995 Jeep Wrangler (YJ) frames are interchangeable with each other.
  • All 1997-2002 Jeep Wrangler (TJ) frames are interchangeable with each other.
  • All 2003-2006 Jeep Wrangler (TJ) frames are interchangeable with each other.

Keep in mind that you might run into problems if you install a used frame from another Jeep on your Jeep. It could be modified, rusted inside, etc. Since a frame replacement is a long and complicated job, no one wants to do it twice on the same vehicle in a short period of time. Installing a used frame drastically increases the likelihood of encountering frame issues again in the near future.

Luckily, you can get a brand new frame that's built specifically for your Jeep model. Throttle Down Kustoms (TDK) frames are among the best on the market, and you can get a model specific frame to ensure precise fitment. For example, you can find a TDK frame built specifically for 1997-2002 TJ Wranglers. Rather than get a used 97-02 frame that may rust sooner than later, you can get an extra strong hand-welded brand new TDK frame that's CNC laser cut and mandrel bent for precise fitment. TDK even offers brand new frames for older Jeeps, such as 1976-1986 CJ7 Jeeps.

Rust Protection is Important

When you go off-roading, your Jeep is exposed to a lot of moisture and other elements of nature. As a result, your frame will rust out over time. So when you replace your Jeep's frame, you want one that's built with rust protection. Here are a few ways a frame can be treated to prevent rust:

  • Sandblast and powdercoat
  • Sandblast and paint
  • Hot dip galvanizing

At TDK, we protect our frames against rust with hot dip galvanizing. In other words, we dip the frame into a hot metal bath that contains molten zinc . This creates a tightly-bonded alloy coating that protects the steel from corrosion.

How Long Does it Take to Install a Jeep Frame?

If you're comfortable with the idea of installing your new Jeep frame yourself, you better stock up on coffee because the project takes about 20-40 hours total. We strongly suggest finding a model-specific tutorial, but here's a general overview of the process:

  • Remove the battery
  • Drain all fluids.
  • Disconnect everything that connects the body to the frame, including:
    • The steering shaft
    • Body mounts
    • Wiring harnesses
    • Hoses, brake lines, etc.
  • Lift the body off the frame.
  • Remove the axles.
  • Remove the engine and drivetrain.
  • Reassemble everything on the new frame.

The project is not for the time challenged. Essentially, you will need to take apart your whole Jeep in order to replace the frame. A few things that are helpful:

  • A model year specific guide or video.
  • A way to keep the fasteners you removed organized.
  • Take pictures of any assembly that could potentially be reinstalled incorrectly.

What Tools do You Need to Install a Frame?

You might be surprised to find out that you would only need hand tools to take the Jeep apart and then reassemble it on the new frame. You'd think that for such a complicated project, you'd need a toolbox full of specialized tools. Most likely you already have all the tools you would need for the job. But it will go a lot faster if you have a good air or battery powered impact wrench.

Keep in mind that you will need a forklift, ceiling hoist, or a strong team to lift the body off the frame. Also, be prepared for rusty bolts. To remove rusty bolts, you need WD-40 or PB blaster. It helps to use a 6-point socket. Try to avoid using a 12-point socket because it'll easily strip the bolt head. If all else fails, use a torch to remove the bolt, or cut it off. When installing the new frame, it's a smart idea to use brand new bolts. You can get a high-quality bolt kit from TDK. You can find them under the parts category for your Jeep model.
