OK, the skids have been on for a week.
Engine Skid...It fits fine...you just have to drill one hole to run one of the stock back bolts thru...or...use the skid hole on the drivers side and drill thru the cross member...no big deal. This is the hole where my 2002 KJ did mount...they must have changed them a couple of years ago. The skid gives good overall protection...the only exception is that it does not entirely cover the two tabs where the LCA meets the alignment eccentric bolt location. I did not put back the CRD sound insulation that sits on top of the stock skid. I figured it would not fit perfectly and could hold water when the material gets wet. One nice feature is that is has a removeable hatch to service the front diff.
Tranny/Transfercase Skid...If fits fine...you just have to drill the same hole or do the same thing I did on the Engine skid above to attach the front to the engine crossmember. Then you have to use the stock hole spots and drop some bolts thru for attachment purposes beside the TransferCase. No big deal...The hole for access to the oil drain plug is fine. If you have a Fumoto Drain Plug you need to enlarge it just a bit. I left the nipple on mine and it protrudes just a bit...If you cut off the Fumoto nipple, it will be flush with the skid. You can reach from the side and access the oil filter if you use "hand tighten' to install.
Fuel Skid...Without a hitch this would be a cinch...perfect fit. With a Hidden Hitch you have to make clearance for the passenger side. You could make a small diagonal cut (on both sides to make it even) or just bend the section in like an ear. I bent mine for now...looks fine. You need to also loosen all the bolts to slip the "legs" of the fuel skid under the hitch attachment points.
All these can probably be easily fitted on gasser too...just a little mod to line up attachment points maybe. Being that they are aluminum, I do not think they are for big rock/boulder crawling. They are fine for my needs...regular trails and highway hazzard protection. I believe they can take a pretty serious hit being that they are 6mm ( a little thicker than 1/4") thick. Withe the removal of the OEM engine skid and the addition of the ASFIR skids...I added a little less than 70#s total and have good coverage...piece of mind from highway gators
I have emailed ASFIR with pics of the points that could be modified...but ...the skids fit fine with small changes as they are. More to come soon!
