03 Avalanche With Factory 410s?

[K.Jump]

Did they make 1500 avalanches with 410s from the factory? My brother-in-law just bought an arrival blue 03 that he says has 410s. I just wanted to check with everyone on here cause I didn't think half tons came with em.

Check the vin code in glove box for gt5.

i could believe if it was a 3/4 ton and had an 8.1l maybe!!

3.73 and 4.10's were definately an option for that year model Avy. So it's quite possible he has the 4.10's. But the GT5 RPO code would verify that has the 4.10's. GT4 is the 3.73.
