Dealer installed GM drop-in liner

Retired Bob · December 31, 2013

I just picked up my new 2014 Silverado
1500 2WD LT DBL with the 5.3L V8. The truck has a dealer installed GM
liner (as do all their trucks on the lot). My last truck (1997) had a LineX
spray in applied when the truck was new – thus 17 years old and the
liner still looks great!

A couple of issues come to mind with

the GM liner – it's like a swimming pool when it rains and the
truck is sightly tail end up – there does not appear to be any
drainage holes at the cab/front end of the liner. Can drain holes be
drilled thru the liner at the cab end of the liner?

And second, the access holes (with the

round plastic pop-out covers at the bottom of the bed) seem to place the ring tie-downs inside
at a greater depth than if there was no liner thus making it sightly
more difficult to secure straps or rope to the tie-downs.

Also, can the top part of the liner

which has places to cut out at each corner actually be cut out and 'pop-up'
tie-downs be installed. These are rubber blocks that fit in the hole
in the top of the bed and then tightened by turning a large screw to
jam them into the hole. Then they have lift up rings that can be
pulled up if needed or remain down (hidden) when not in use so the
top of the bed is smooth.

Thanks in advance

Yes, you can drill drain holes. Would be best to lift the liner out so you don't hit the truck with the drill. It just drops in and doesn't weigh much.

Yes, you will have to reach in a little further.

Yes, you can remove the knockouts on top.

Sell it back to the dealer! Unless you like stuff slamming around back there.

You can drill the holes but, I would not recommend it. Water will get under the liner and eventually start to rust. Plus it might start growing mold under there. As stated above I'd sell it back to the dealer.

^^get rid of the liner.. It'll rub away the paint and it'll cause rust in the long run.. Drop ins are junk

See if the dealer will trade out for a bed rug.

I always did spray in lines on my trucks due to the beds usually being in bad shape when I got the truck. Since this one was new I went with the bed mat this time as I only wanted to keep the stuff from scratching the floor as I don't ever haul anything.

I like BEDTRED. The backing is not abrasive so the paint won't get injured, and it is cushioned. Objects don't slide around on it, either.

As others have stated concern with rust it liner rubs off the paint in the bed and stuff sliding around.

I got a drop in for $150.00 I figure if the bed starts to rust I'll invest in a spray in. If I had more $$ I'd have just done a line-x plus my truck is a lease so IDK if the invesntment in the spray in would pay off.

What? I am saying the drop in sucks. The truck has been parked in California most of its life with a 3 year stint in Florida.

10 years with your drop in liner. I'd say that bed looks great. If you were from the north east it probably be a lot worse. All the road salt out here wreaks havoc on our beds.
