UCF LOPRO Transmission Mount

**undercoverfab** · 03-15-2010, 12:45 PM

The UCF LOPRO Transmission Mount was designed to allow you cheat.

For years people assumed you needed drop-down spacers for the stock transfer case skid so you can install a 3" suspension lift on a TJ - Not with the LOPRO mount!

Everyone also thought you needed a body lift to install a TT skid on a TJ or LJ - Not with the LOPRO mount!

There are many ways to take advantage of the clearance afforded by the LOPRO mount. Some probably haven't yet been considered.

The new mount is a direct replacement for the factory transmission mount on the '03-'06 model TJ and LJ. More testing and development is required before we release the LOPRO mount for the early model TJ ('97-'02). It is almost 1" shorter than the factory piece. This lowers the transfer case down into the skid plate by the same amount. That 1" of extra clearance can go far toward reducing metal-on-metal vibration and avoiding body lifts. Some increase in felt drivetrain vibration should be expected with this transmission mount.

Some modifications to the factory bracket that connects the transmission mount to the transmission will be necessary. You will be required to shorten a flange with a sawzall or angle grinder. The LOPRO mount will be shipped unassembled and unpainted. You will need to paint all the bare steel parts and install the bushing.

Note:

(1) The LOPRO mount will not be directly compatible with the UCF High-Clearance Transfer Case Skid Plate if used with the 42RLE automatic transmission. The transmission pan would interfere with the bent front edge of the skid plate. The front edge of the skid plate could be modified to allow the parts to be used together.

(2) The LOPRO mount should not be used with 32RH automatic transmission in the early TJ because the adapter that attaches the transmission mount to the skid plate doesn't adequately support the bottom side of the LOPRO mount.

Nice product, I can see where it could help in some situations. Heck I think it might even help my TJ with its bellyup skidplate.

Did you ever get a chance to measure the transmission mounting surface offset on your skid? Let me know so we can get something going.

Thanks,

With 2in bds springs, bodylift ,mml, and your lopro mount, can I use your high clearance skid without the sye crap, if not ill keep the stock skid without the t-cse drop till i can afford the sye/ds/arms/etc.

I would think that combination would be okay with the stock shaft. It would net out at about 3" of effective SL with a MML.

im confused it looks to me like i would be just as well off mounting my trans strait to my belly pan.

could you explain how that isolates the trans from the body?

The LOPRO mount uses a combination of 2 bushings to isolate the transmission from the skid plate. The first is a 3/16" sheet of soft rubber that separates the 2 halves of the mount. This pad provides tension so that the power-train can transfer energy to the secondary round bushing that's located on the outer edge of the mount when under load in forward gears. This secondary bushing is what really holds the mount together and what provides all the vibration isolation when in reverse.

very cool. i run a 1"MML,a 1.25Body lift a jeep medic tummy tuck skid and a cv rear shaft. I would like to add this mount to the works i feel like it would help even more.

2 questions

1. will this modification allow the use of the engine skid?

2. how much. if any, would it weaken the skid.

Please make an Ultra High Clearance model for the 42RLE with a 1.25 BL
a wish, i know, but damn i want it.

I looked at this on your website, and you say that I need to modify my catalytic converter. Can you tell me what modifications I need to make to install this? BTW I just installed your tranfer case skid..Great product!
