A parking place for my ramblings.
My 2005 GMC Sierra SLT 3500 dually

My 2005 GMC Sierra SLT 3500 Dually

I’ll post a sad story here eventually that drove me to purchase my Duramax.  But, I wanted share a few recent things in regards to my truck.  I could not be more satisfied with this trucks performance.  My only regret is that I did not buy her new.  I cannot believe it took me 10 years to purchase my own Duramax.  I’ve driven 3/4 ton Duramax trucks as company vehicles and even a rental of two.  But, having my OWN truck has been the BEST!


I’ve owned the truck a little over a year at this point.  Typical for me, before I actually signed the purchase papers I had ordered performance parts for the truck.  Over the last year, the truck has received several upgrades.  Those of you with trained eyes can see a few in the picture above.  But, most are under the hood.  I’ll get around to listing them for those of you who just have to know.  But, that’ll be another post…


I’m at the point of wanting to make some exterior changes.  I’ve been very fond of the Denali monochromatic look and the front end.  I’m thinking it’s time for some exterior mods.  I’ve been eyeing the new 2014/15 rear bumpers on the new GMC Sierra’s.  I was able to get a hold of one and this turned to be one SWEET looking upgrade!

I installed a 2015 3/4 ton step style bumper.  Yes, if you can imagine it, the 2015 GMC rear step bumper fits.  It’s not exactly a bolt on, but only required careful measuring and drilling some new holes and the new 2015 bumper bolted right up.  With my dual fender flares it was also necessary for me to trim some of the plastic on the bumper to keep it away from the paint.

The spare tire tube and trailer harness matched right up.  I did have to purchase a new trailer plug receptacle.

I couldn’t have been more satisfied with the end result.  I had not expected the conversion to have cleaned up the rear of the truck so much.   The bumper was originally chrome with back up sensors, of which I welded up and then did some metal work to smooth the welds and a little more work to get it ready for paint.


I had upgraded to a heavier duty receiver hitch.  Which you can see in the original picture, had created a large gap between the bumper and the top of the hitch.  Kind of an eye sore in my opinion, not that there was much I could have done at the point.  The 2015 bumper, it’s a taller bumper and has filled that gap very nicely!


Next mod, new wheels!  I’m sticking with 16 inch wheels as I have recently purchased new tires.  My next post will have some pictures from that upgrade!


Future upgrade, Denali front clip!  I’ve never been fond of the offset GMC logo in the grill.  I’m proud of it being a GMC and want to keep the logo.  But, I don’t like the GMC logo in the upper half of the grill and the front of the truck, just does noting for me.
