ORI GVM & Lift Packages
Offroad Industries GVM & Lift Packages
The Silverado 1500 leaves the factory with a 3,300 kg GVM and about 757 kg of payload — not much once you add a canopy, fridge, water and the family.
Offroad Industries' federally approved packages lift that to as much as 4,250 kg GVM and 8,750 kg GCM, or keep the truck in the NB1 category with a 2–6" BDS lift on 35s or 37s. LTZ, Trail Boss and ZR2 are all covered.
Factory rating: 3,300 kg GVM · 7,160 kg GCM · about 757 kg payload
