Gm has a standard mirror option for the 2500

Ordered a GMC 2500 double cab 5 weeks ago was called yesterday, said Gm is done with "21" regular cabs for this year and might run a batch of double cabs but won't have a decision till next week. So maybe will have to order a "22"

curious as to what state nards?

thank you!

Try this, on the 2020/2021 GMC/Silverado 2500HD's what tire size's can the dealer program the vehicle for?

Does any one know if the tire size com. program is the same for 275/70/18 and 275/65/20 or if GM has one for the exact tire size?

As for the fender liners being different I only see one part no. L and R for the 2014's maybe the older trucks but have doubts about that also

After 3 days with the new module the FM reception is better and the HD holds a little better than before. While not an earth shattering diff. the improvement is welcomed

Mine is going in for new module tomorrow will post update after with any diff. in reception if at all.

U Tube you can find vidios for the kits
