Vehicle-specific approval pathways. Verify the exact vehicle, registration status and current certification requirements before choosing a kit.

Official approval basis
Tough Dog’s official information identifies 4Way Suspension Products as a recognised Second Stage Manufacturer and explains that complete GVM kits are tested to maintain applicable ADR compliance.
Federal approval may apply before first registration. For an already-registered vehicle, the federal compliance data is used with inspection and certification by an authorised state engineer. Exact requirements must be confirmed for the vehicle and jurisdiction.

A vehicle that has never been registered follows a different approval path from an already-registered vehicle.
03
The dealer verifies the applicable kit, upgraded GVM and any vehicle-specific requirements before ordering or fitment.
04
The required compliance identification, inspection, engineering and registration steps depend on the approval path and jurisdiction.
