I am looking into adding a bit of under body protection to my 2018 2.5i Base Premium Forester. I believe the current under guard is plastic but I see that Subaru offers steel and in come cases aluminum under guards for the engine, transmission, muffler and differential. These offer a significant savings over the aftermarket protection and since I plan only moderate off road use and not rock crawling or racing I was wondering what opinions members had of these options.

I do see that from pictures the diff protector looks like a "this looks cool" mod as opposed to anything that would provide any real protection since the supports look pretty weak.

The Subaru part numbers are:

Part Number: E515SSJ000 Engine Under Guard - Steel
Part Number: E515SSJ010 Engine Under Guard - Aluminum
Part Number: E515EFL201 Subaru Forester Differential Under Guard - Steel

From https://www.subaruforester.org/vbulletin/f139/subaru-under-guards-questions-789753/ I see that the steel is 2mm ( a little over 1/16") and the Al is 3mm (a littl under 1/8") kind of a toss up for strength.

These designs are admittedly not the "slide over rock" types on the after market but is that really needed.

Anyway what do you think?

For your purpose I think they would be fine. Forget the rear diff protector - not needed as that is the strongest part of the car! I have only ever had an engine sump guard and the car has done a lot of serious rock climbing. I do have a fairly substantial dent in my fuel tank though ;-)

Will these Under Guards fit 2014-2018 Forester? I thought they were only for 2019 and newer? If I'm wrong great, I'm getting one for my wife's 2016!

That is a major bummer since they are significantly less expensive than the after market skid plates. I might just have to buy one and see what the difference is and whether or not it is usable.:wink2:
