View Full Version : Holy Cow that was quick drilling!

I don't know if this is a good thing or a bad thing but last night I started installing my Torklift camper tie downs on my truck, these call for two holes drilled in the frame and one in the box section. I prepared myself for a long night, got two drills and two bits of each size. Started with a 1/4" pilot hole and "Oh my God!" in less than a minute I was through the frame.

Nine years ago, when I bought my first GM (1500 Sierra), I installed step bars. Back then you had to drill into the frame to get these installed unlike today. I think I spent two hours on each side just drilling. Killed my Dad's electric drill, went through 4 bits total and still had to switch back and forth every five minutes on drills to avoid overheating them.

Either these new drill bits are light years ahead of the top-line bits back in 94 or these frames are nothing like the frame of my 1500. This scares me a little knowing that my camper will be basically held on by the tie downs bolted to this frame.

I've got a great story that I tell year after year regarding my 1500. Back in 1995, shortly after I installed the nerf bars, a guy driving a Nissan Pulsar found himself in the left turn only lane at a light and pulled into my lane as I was going about 20mph. Right into the side of me as I passed by. The truck was only 5 months old and I was beside myself since when I looked in the rear view mirror at his vehicle his bumper was hanging off, his hood was popped up and his windshield was shattered. I pulled over to inspect my damage and looked for about 5 minutes. Finally I noticed a small rub mark on the outside of the nerf bar (since I installed them they stick out a little too far for legal purposes) and that's it. I was so proud of that truck then and I still am now. I don't think this would necessarily be the case if the same event happened with my 3500 but maybe I'm wrong.

The frames are thinner thats for sure.
I don't know why but the are supposed to be tougher as well.
New bits are helpfull as well. The best 1/4" drill bits I have found are Greenlee hole saw center bits. I spray with WD40 as well while drilling. Slow drilling is important as well. Don't use max rpm.

lighter frames equal better gas mileage

less material engineered better

I got the TorkLift tie-downs

you'll like them, they rule

Last year I drilled some holes in my frame for tie downs> I too was shocked. It is not just the thickness of the frame. The steel is very SOFT.

I have the torque lift tiedowns also and you will have no problem. I haul a 5000 pound artic fox with a slide and it is as solid as a rock they work great.

The frames are formed with a new process called "Hydroforming". Meaning they are formed under high water pressure. This allows for the metal to be much thinner, but have more tensil strength. GM perfected the process on the Corvette.

Regarding camper tiedowns, I found that the OEM hitch is made of tubular steel and that a 2.5 in. threaded pipe nipple screws right into them up to the last thread. I then welded them and painted them black. I used a six inch nipple for the permanant mount and then stepped down to a 2.25 inch 10 in. long threaded pipe (for easy removal), drilled a 3/8 in. hole near the ends and inserted a stainless 3/8 in. eye bolt to mount the camper and put a cap on the end. I then drilled my Westin nerf bars and inserted eye bolts in them for the front. I have traveled many miles and over rough terain with no problem. That's with a 4K+ Elkhorn 11x camper.

FstTrack, do you have any pictures of your rig with the camper on it? I'm installing the Tork Lifts to put an 03 Arctic Fox on my 3500 which will weigh about what your's weighs and I've got a very similar truck set up with the CC, 4x4, Duramax...

How's the truck handle with the big Arctic Fox on it?

It handles it great, dont think I would want to haul anything heavier but I pull a 9000 pound trailer behind it. was a little to much with camper and trailer it handled it but is so much better with the air bags you wouldnt believe it. No pictures. camper makes the truck look small you wont loose it at wally world.
