I bought a 2013 3500HD Dually to replace my 2006 LLY and this is my build thread on the new truck. I had wanted a dually for a long time and the right deal fell into place, but stock it did not stay for long.

Here is a list of the mods that are planned.

  • 9W LED back up bulbs
  • 55W 4300K Low beam and 35W 3000K Fog lamp HID (have a set of custom cleared and FXR projectors to be installed)
  • Rigid Industries 20" bar in the bumper (next round of mods)
  • Color match the exterior, grille, front bumper, mirrors, hood vents, rear bumper caps
  • Paint protection to the forward facing painted surfaces
  • Debadge exterior
  • All Sales 21" Stubby Antenna
  • Streetside Auto Tri-Fold Tonneau cover
  • Rhino Liner(next round of mods)
  • Putco Interior LED Kit
  • CoverCraft Carhartt Gray SeatSavers
  • WeatherTech front and rear liners
  • Tinted front windows 45%
  • Summer setup 20" Eagle Alloys 056 Bolt on wheels, polished finish
  • LT275/60/20 Nitto Dura Grappler (changing to 275/65/20 Toyo Open Country MT in spring)
  • Winter setup 17" OEM Alcoa wheels
  • LT285/75/17 Nitto Terra Grappler with 1.5" Fred's spacer
  • Cognito Stage 5 Leveling kit (next round of mods)
  • 5" MBRP Filter Back stainless
  • 6" MBRP Dual Wall tip
  • Air Dog 100 (next round of mods)
  • Nicktane Filter Head with CAT filter (next round of mods)


My main goal with the truck is fuel economy and being able to haul more than my LLY did, and look good all at the same time. My LLY averaged a lifetime over the 115k miles I put on it in 5 years, right at 18.7 mpg. That is a mix of towing, mainly highway(85 mile commute) and some city driving. I hope to return to that economy with this truck, untuned.

Hand calculated fuel mileage:
First refuel at 220 miles was 14.41 mpg
Second refuel at 650 miles was 15.33 mpg

I will continue to add to the thread as I complete mods.

Here is the first pic I took of it:

Here are the updates.

Exhaust is on:

Old


New




Paint work is all done.





GM Accessory Grille in white





My detailing buddy Greg came up and we did a tandem polish and applied Opti-Coat 2.0. No waxing in the near future for me.







Installed a set of Husky mud flaps, they are doing construction on the highways around here and I got tired of the road oil on the truck. I also ordered a set of new OEM headlights and sent them to Phil Sheridan to have him remove the amber corners and a set of FXR bi-xenon projectors in them.









Silverstar bulbs will replace the amber ones.





Here are a couple updated pics of the truck.

Looks really nice, expecting that fuel mileage without tune might be difficult but good luck nonetheless

I have come to the realization that this is probably true. I use my Fuelly account and already have managed 14.4 mpg in the 9200 miles/5 months, towing quite a bit. I had a few 17 mpg rounds, but a string of 12's brought the average down. I am in the hunt for a RCLB LB7 to DD to keep the miles off of it and use it around the shop.

Yea my lb7 reg cab zf got me 22.2 on a highway trip pulling a small 16 foot bumper pull trailer with another long bed, bumper, tailgate and tool box. Was super excited once I did the math.

Thanks to Cornell for the contact on the LED parts. I ordered a 20" bar for the bumper, 2 - 3" white dually spot and 2 - 3" white dually flood for the fog light area and 2 - 3" black dually spot for the back. I ordered the Rigid bumper and fog lamp mounts to put it all together. Will do the headlights at the same time.

Also ordered the DeeZee easy down tailgate shock to throw on when I do my BedRug BedTred that should be here this week. My Bilstein 5100 are on back order until March so I have to wait on them. May order the Cognito UCA's and do it all at once.

My Toyo MT's in 275/65/20 arrived so I am ready for spring modding to begin.

LED's have arrived, BedTred has been installed and is a nice piece. I also sold the Eagle 20's with the Dura Grapplers, so going to have to decide on a new wheel to go with the Toyo MT's. Also ordered a Pace Edwards Jack Rabbit, had to after installing one on my buddies truck, such a nice piece.

Can't wait for the weather to break so I can start in on the modding.

Well I ordered the Eagle 057 black and machined to match up with my Toyo MT's. Going to give the black wheel look a try on the dually. Should be a good look, and give it the storm trooper look.

Also carved out some time to install my BedRug BedTred and my Pace Edwards JackRabbit tonneau cover. Could not be happier with both products, they are great pieces.





Then I spent a few hours on Saturday morning cleaning it up.





Also had a chance to clean up my wifes new car, after the snowy week home after the ride home from Texas.

So "Casper" was filthy from the sour weather we have been having. I finally got a chance to give her a bath and a wipe down with some FK425.



Washed:


All finished:



Also pulled the Carhartt seat covers for the first time since I installed them at 500 miles, at 14k miles now and the seats look perfect.





Also got the windows on my wife's car done and the new wheels put on.
