The Hidden Body Lift

Here's a look at what the rear body mount isolaters can do for the 6 under the door.

The rear upper is .875". The rear lower about .75". And the bolt head adds another .25".

Under the door, the upper is about 1.25". The lower is about 1.125". And the bolt/washer and another .25".

As Blaine described earlier, just replacing the lower isolaters under the door with the ones used for the rear, along with a recessed flathead bolt, the lower isolater could be raised up an additional 1/2" into the mount.

If the upper piece is used, the entire mount could be raised an additional 1/4".

As Blaine described earlier, just replacing the lower isolaters under the door with the ones used for the rear, along with a button head bolt, the lower isolater could be raised up an additional 1/2" into the mount.

If the upper piece is used, the entire mount could be raised an additional 1/4".
So to simplify, overall the head of the bolt can be moved 2” up from the OEM position?

Part 2 or 3 of the hidden body lift!

I grabbed 8 of the smaller lower isolaters from a couple junk yard TJs. Only 6 are needed. These are found on the rear corners and the rear upper shock mount crossmember.

I'm using 1/2-13x 3" flat head socket cap bolts.

And I forgot to get a shot of pressing the bolt head into the isolater. Use a socket that is the same diameter at the upper isolater sleeve and use the bolt to create it's own recess.

The next step is to modify the upper isolater.

The sleeve needs to be cut back to the next step that fits through the frame mount. This section also needs to be sanded down to fit into the smaller lower isolater.

Another likely better option is to use a drum sander to open up the lower isolater. This retains the bit of rubber that normally separates the upper and lower isolaters for better reduction of NVH. Though, so far, I can't tell a difference using my method.

Here is the final result. The lower isolater is fully protected within the Genright raised body mount.

We need to get my body mounts on the schedule! This is awesome.

FYI to anyone wanting to do this and save a trip to the junk yard, the Crown part number is 52002659. They're available everywhere online for as little as $4 ea.

FWIW, I paid $5.29 for eight at the junk yard. Including the admission fee.

Some might not be so lucky to have a yard nearby, or find the convenience of not spending a couple hours hunting them down and getting dirty worth $20. Other's might think of going to the junk yard as cheap entertainment. I'm firmly in the former camp :)

Where's the closest yard to us that would have any and have any that one wouldn't mind using?

I’m guessing yours are like ours, TJs don’t last a few days until they’re stripped to the bone. However maybe this is the one part people aren’t jumping after?
