Breakout Technical Forums Are Here

Recommended Posts

Now that the 2020 HD's are starting to hit the lot and people are taking delivery we're breaking out the HD technical topics into their own sub forums. 


These new sections are:

2020 Silverado HD & Sierra HD Troubleshooting

2020 Silverado HD & Sierra HD Mods

6.6L Duramax Diesel & Allison Powertrain (L5P/MGM)

6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)


Next time you make a new post in the 2020 HD forums, please take a moment to see if it may be appropriate to put your topic in one of these sub-forums.
