What is best engine and transmission skidplate?
 
Also needs to be compatible with a good T-case skidplate for a 242 T-case.

This is for a 1999 XJ with Automatic Transmission and 242 T-case

AEV engine skid is a damned good design, although its pricey because it's AEV.... Not that XJs need engine skids as much as TJs do, our axle sits directly under the oil pan and helps protect the engine.

As far as transfer case skids, I'm partial to the TNT belly pan, high clearance crossmember and t-case skid all in one.

That combination of skids is compatible with each other?

Please explain the high clearance cross member. Does it affect driveline angles?

I wouldn't have recommended them if they didn't work together. The belly pan doesn't rase your driveline, it's not as thick so it doesn't hang down as far.

Does the TNT belly pan cover the auto tranny?

RockRodHooligan 04-09-2013 12:05 PM

The back part of it, but not all.

How do you protect your transmission?

I do not see the TNT high clearance cross member at TNT's website.

Is the TNT high clearance cross member for sale separately
from their Belly Plate system?

I might want the high clearance cross member by itself,
but the Belly Plate is to much cost and weight and over kill for me.

No offense. I'm sure the Belly Plate system is good for someone who needs all that, but I don't.

RockRodHooligan 04-09-2013 09:19 PM

Well...... I don't know that it's an issue?

You mean the uncovered portion of transmission is not at risk? Not in a location of high risk?

I'm not trying to be a smart butt. I really don't understand these issues and want to learn from you.

The belly plate system is what I was referring to, they used to offer just a high clearance cross member a few years back, may be able to call and ask about just the crossmember.

I am considering a Rusty's engine-tranny skidplate vs a Skidrow engine-tranny skidplate.

Anyone have one or the other? Which do you think it better and why?

I had Skidrow before on a Wrangler, and it was good, but Rusty's offers a 1" drop cross member that lowers T-case 1" without losing any ground clearance (or so they claim). This intrigues me because if it works as advertised, I would not have to get a slip yoke eliminator and CV drive line for my 1" to 1.5" lift.

Note: I have a 99 XJ with AT, 242 TC, and Chrysler 8.25 rear end. So If I lift 1.5" or more, I'll probably have vibrations, until a solution is used. The Rusty's 1" drop cross member sounds like a potentially good solution because no loss in ground clearance, improved drive line angles due to 1" lower Tcase, and less money than a slip yoke eliminator..

Regarding (AEV) Nth Degree engine skid. I had one on an LJ in the past. I never offroaded it in anything but sand and snow. So never tested the skid plates.

Doesn't the (AEV) Nth Degree engine skid leave exhaust header pipe vulnerable next to the engine oil pan? Don't the Skidrow and Rusty's engine-tranny skids protect the header pipe, as well as the oil pan. Am I missing something?

its all about what you prefer, and your application man. if you want to protect all of those things better, than you would probably want to go with something like what rusty's offers:

rusty's skid plate

that will cover everything, up to the crossmember. you would have to add something behind the crossmember to protect your tcase such as this as i believe you stated you have a 242 tcase.

and as for needing an SYE for a 1-1.5 inch lift, i think thats crazy man. the vibrations you would get from such a small lift would be minimal, at best. typically tcase drop and SYE become a necessity around 3" of lift or higher.

Agreed, engine and transmission protection doesn't seem to be as important on the XJs as it is on TJs, the drivetrain sits up higher in the chassis. The big one is protecting the t-case. Unless you make it a habit to play in big rocks, I wouldn't worry about them.

3"/31"s All I had was the TNT belly pan, the high clearance skid helps a lot.

It was not common for me to play in rocks THAT big, but I did play in rocks often.

As for the Rusty's pan with the built in 1" drop.... You don't need it. XJs with the Up Country package came stock with a 1" lift over the regular XJs, with 2" if for some reason you do have vibes, you could space your x-member with a couple 1/4" washers. Even with more lift, an SYE is always better than dropping your driveline, even if its just a hack-n-tap.
