Key components
Capability
Best For: Heavy-duty touring. If you have a bull bar, and a heavy tow ball weight from a large caravan, this is your sweet spot without having to upgrade your wheel and tyre package.
Benefit: The DSC adjustability allows you to "dial in" your ride—stiffen it for the highway and soften it for the tracks at the turn of a knob. Fox’s premium shocks setup for the Chevy Silverado 1500.

All stages retain 4500 kg braked towing while increasing legal payload and GVM.
GCM remains at 12,474 kg across all builds — meaning towing capacity isn’t reduced even though payload increases.
All stages require appropriate wheel/tyre upgrades, especially for larger 37″ tyre compatibility.
SSM (Secondary Stage Manufacturer) federal approval applies Pre‑Rego only (pre‑initial registration).
ORI GVM Stages Explained:
Best for: Light touring, family trips, and moderate load carrying.
Stage 1 is the entry-level GVM upgrade, lifting the Silverado to around 5500 kg GVM and significantly increasing payload while keeping factory towing capacity. It uses Fox 2.5 HTO shocks, upgraded leaf springs, and a 3-inch lift.
This stage is ideal for owners who want to carry camping gear, a canopy setup, or occasional towing, without going to a heavy-duty suspension package.
Best for: Long-distance touring, heavy canopy builds, or towing caravans.
Stage 2 increases the GVM further to around 5900 kg and adds Fox Performance Elite DSC shocks and heavier 500 kg leaf packs, improving load handling and ride control over rough roads.
This package suits vehicles carrying permanent weight such as drawers, fridges, rooftop tents, or touring equipment.
Best for: Heavily loaded touring rigs or work vehicles carrying constant weight.
Stage 3 keeps the 5900 kg GVM but upgrades the front suspension to a BDS coil-over conversion with Fox Performance Elite shocks, improving suspension articulation and ride comfort.
It’s best suited to customers who want maximum comfort while carrying heavy loads or travelling long distances off-road.
Best for: Vehicles with variable loads such as campers, slide-on campers, or heavy towing setups.
This stage builds on Stage 3 but replaces the rear leaf springs with Kelderman air suspension, allowing adjustable ride height and load levelling.
It’s ideal for customers who frequently change loads or tow large caravans and want better ride comfort and levelling under load.
Best for: Customers wanting larger tyres, increased ground clearance, and strong payload capacity.
Stage 4 introduces a 5-inch suspension lift with heavy-duty components while retaining the high-capacity GVM upgrade.
This stage suits drivers building a touring truck with larger tyres and improved off-road clearance.
Best for: Off-road focused builds with large tyres and aggressive stance.
Stage 5 increases suspension lift to around 6.5 inches, typically using BDS suspension components and performance shocks.
This stage is ideal for customers wanting maximum clearance for 37-inch tyres and a lifted off-road setup.
Best for: Premium off-road builds and show-level touring trucks.
Stage 6 combines a 6.5-inch lift with coil-over suspension, delivering improved suspension performance and ride quality compared to standard lift kits.
It’s best suited for customers wanting the highest performance suspension setup with maximum lift and load capability.
