Did this last year and I was very lucky it didn't take out the front a-arm mount or t-case.


Since I can't afford a lift kit for more clearance, I'm going to build a skidplate to cover the entire underside. The red dots are bolts


It will be one piece cut from a 4x8 sheet of either 10 gauge and will cover the front diff, tranny, exhaust, and t-case. I'm going to drill holes in the cross members and install 5/16-24 steel rivnuts for quick installation and removal along with six 3/8 bolts(2 front and 4 rear)
Here's a pic showing the dimensions. The most forward 11"x16" section will be bent up at a 35* angle to replace the splash guard.


I'm going to drop the plans off at the waterjet tomorrow so I may have it back by Friday. I'll keep it updated with pics of the completed installation.

Edit: The skidplate is 21 sq/ft. Using 10 gauge will put it at 115 lbs. I was going to use 3/16 but the added cost and weight(161 lbs) was a turn off.

I'd hate to pull it off everytime I change my oil, might not be too bad tho.
Should look good tho!

you could put a oil filter reloaction kit on there or maybe make a hinged panel simialr to the s10 zr2 skid plates that open for you to get to the filter.

Looking forward to finished pics.

It would be a lot cooler if you could thread the holes to accept the bolt or weld nuts on top so you dont have to have a wrench on the topside top take it off.

It will protect your under carriage. However, if you offroad in water with weeds, tall grass, or sticks, its a pain in the neck to pull out all of the debris.

the post above makes a good point, put some holes in it for water drains

Much needed if you wheel that hard :imo good luck with the build :head3:

Id much rather do that than risk twisting/bending/breaking shit :shrug:

put some of the holes like on the fabtech traction bar. There is a technical name and IIRC it doesnt loose any strength but helps with weight and in this case allow the water to drain quicker

One of those with 1-2" holes drilled in a pattern for draining, oil filter access and weight loss would be bad ass! If I had access to a waterjet or something like that, I'd build one. With enough holes drilled, you could prolly get it under 100lbs.

Or just build it properly and have it overlap so that it's can't catch in the transitions.

As for water build up, I dont really see much of an issue. Just make sure you put some thought into what could catch and how to avoid it. It should be a pretty straight forward build.

Lastly, if you build it right, with the right material that is weight efficient, you might gain a slight increase in mpg due to helping the aerodynamics.

You're not going to do much to help an impact like what caused the dent in your front crossmember from hurting your t-case with 10ga and a span like you have from the tranny mount x-member and the rear most pictured crossmember.

The steel is just going to deform and the impact will get transfered to the mag t-case and crack it or the tranny tailhousing.

I like the idea (especially the use of the pem/rivet-nuts to secure it) but without some kind of stucture to minimize the unsupported spans I don't think 1/8"+.010 is going to provide quite the results you're after.

Getting kind of the same feedback on a local 4x4 board. I may end up using 1/4" with a mix of slots and holes to lighten it up. I have dimple dies(1/2-2") but you can't really dimple anything thicker than 11 gauge from my experience.
