2020 Sierra Regular Cab (2door) Short Bed Build Thread.

Recommended Posts

Starting this thread to document the build on my 2020 Sierra. As I live downtown I want a vehicle that’s small and easy to get around in and something fast to play with. 
 

GM doesn’t make a single cab short bed and definitely doesn’t make one with the 6.2 so I’m having one built. 
 

Starting out with a 2020 Sierra 2 door long bed (8’). Going to chop the frame down and install a short bed (5’8”) on it. 
 

Moving forward after that we are looking to put a supercharged 6.2l bored out to 416ci. 
 

Started off with the easy stuff like tinted windows and new stereo (new door and tweeter speakers, amps and 2-12” subs). Now it’s at the body shop for the short bed conversion. Then to suspension for a 4/6 drop. A brief stop for some Katzkin leather seats. Then to the performance/speed shop for the engine work. Then off to have the trans built to handle the aprox 850hp the engine will put out (@ the crank). 

 

Just started the fun part of the build process at the body shop. 
 

Here they are cutting down the frame.

The body shop doing short bed conversion is Leading Edge Collision in Houston. You can follow the body shops part of the build on Adan, the shops owner’s, Instagram. @Adanomyte. https://www.instagram.com/adanomyte/?hl=en

Any reason you went with the 5'8" instead of the 6'6" bed like the SCSB used to come from the factory? Might have saved you some money on a driveshaft. 

 

Very cool project any way you look at it!!!

I want it short and sweet. The easier it is to maneuver and park in an urban setting the better. Plus there are only a handful of custom 5’8” bed single cabs out there, more unique. 
 

Plus in the grand scheme of the build a $500 custom shortened driveshaft is insignificant.

True, but you will probably mostly notice it being a little more "squirrely" under WOT with the even shorter wheel base.

Ah, the good old days. I did that to a new 1990 single cab, drw 3500 gmc in '90. Really made it turn. Still running it today. Just installed a new gmc long block this winter. Terrible in snow, but great traction when dry.

 

Enjoy the ride.

I have a 2020 6.2 sierra crew cab full size bed mainly a tow vehicle for my trailer and sxs. are you going full time AWD with that amount of power? I have trouble putting the power down in RWD 100% stock especially when I am towing I can get wheel spin when it shifts up to around 50 when merging on to the highway if the road is even mildly damp towing I have to put it in auto/4 high.

I have a crew cab, standard bed, Duramax, 2500 for when the weather is bad or when I need to tow something. Taking the fun truck out in inclement weather is optional and probably not one I’ll use that much. And yes I expect to leave the truck in 4wd Auto mode most of the time. To my delight it stays in Auto mode when you restart the vehicle after shutdown. I was a little worried it would electronically default to 2 High.

Have my (bought new) 2007 NBS SWB RC still.  This is after selling a RC step side 1990 Sierra GT.   Wish GMC would make one again...with AWD and Forced induction 6.2.... Call it the Hurricane  (larger than Syclone). Would buy one in a heartbeat. Until then I enjoy watching these amazing builds. Here is one that was also cool.

That is Adan’s truck, the owner of the shop that is doing mine.  You can see more of it on Instagram, @Adanomyte.
