If you live where they use road salt undercoating is a must, just did my 15. I had 11 F150 and did not undercoat it and it looked awful underneath.

Put on th husky liners the other night. Drivers side was a real PIA had to use a dremmel to relieve around the flare xmas trees and drill a hole in the box side for the rear hole to line up (painted hole to be safe). Pass side was easy with no mods. Looks so much better Ford should have this as std on Lariat up..…

I have lived in the snow belt for the better part of 27 years. You do not need to undercoat and in fact it is not recommended. I have talked to many technicians on this topic and they are very consistent that they see no improvement in corrosion control from undercoating. Further back in the early eighties when undercoating was popular, major car manufactures came out as flat against it because it trapped moisture and made the problem worse. Further PPG paints came out with a surface prep product that is used by all major vehicle manufactures that stops rust in its tracks. It has been in use for close to twenty years now. You do not need to undercoat. If you want your vehicle to last a lot of years, in excess of ten or fifteen you can perform annual corrosion control maintenance and spray seams and spot welds with various corrosion blocking products. Clean up surface rust on the underside, etc. I keep my vehicles a long time. I start to see surface rust at the five year mark. I see problem areas start to develop around the ten year mark.

I had trouble with the same hole but I drill the liner cause I wasn't putting a hole in the truck.

I would recommend getting the factory liners...

I bought husky liners and while adequate, they do not fit perfectly...getting the holes to line up was fun and they did not seem to take into account the plastic pins in the finder along the edge...it also doesn't fit well behind the screws on the bottom of the fenders....its almost like its a general purpose liner that fits multiple vehicles, not specifically designed for my vehicle like they claim...theres seveal areas where its molded to curve different than what my wheel well was, and the bottom edges were off...

they are in and they look fine...like every liner on the market...its not like the husky liners are particularly tough or rugged, fairly thin plastic all around...but the factory ones have to fit better I would imagine and protect just as well....

now that I think about it wonder if trimming about half an inch off the bottom on each side would make it fit better...thats where the most binding is....

You must of been lucky, as I said my 2011 looked like a 20 year old vehicle underneath. My daughter has a 2005 Ford 500 and was undercoated every year and the 2005 looks new compared to the 2011.

I only drilled a small hole and then painted over it both sides. I live in Texas so salt corrosion etc. is not a concern.

Mine certainly didn't feel thin - it took some force to bend them to fit - I do not know of the gage of the factory ones, but I would guess they are similar,

my dealer had some in stock,got mine installed on my truck as a" throw in"
no charge,after deal was made. A buddy of mine went from chevy at my dealer to a new FordI think thats why "no charge for the liners for both of us.Both of us got the Ford bed cover,installed, for $166.00. I deal through the sales manager,he is happy to put Chevie owners in a new Ford and treats me right.

I went with the Ford liners purchase through my dealer. If ordered during the build Ford required some other content that I didn't want. I think it was chrome running boards. The liners were a easy install. I have a silver truck with black running boards having the front wheel wells being black and the rears silver the addition of the liners balanced the look. The liners definitely quite the ride on gravel roads.
