Read moreFormula 4x4 GCM Upgrade Kits are designed for 4WD owners who need to legally and safely operate at increased combined vehicle and trailer weights. When towing caravans, camper trailers, boats, or work equipment, factory Gross Combination Mass limits can be reached quickly, placing additional strain on suspension performance, towing stability, and overall vehicle control.
Formula 4x4 GCM upgrades are engineered as complete, vehicle-specific suspension systems to support increased towing demands while maintaining balance, control, and predictable handling under real-world Australian conditions.
Modern 4WDs are commonly used for towing while also carrying permanent accessories such as bull bars, winches, canopies, drawer systems, towing equipment, and tools. These additions reduce operating margins and can push a vehicle close to or beyond its factory GCM without the driver realising.
Operating at or over factory GCM limits can negatively impact towing stability, braking performance, suspension durability, and vehicle control. A Formula 4x4 GCM Upgrade Kit improves suspension support and towing stability, helping your 4WD remain predictable and confident under increased combined weights.
The Formula 4x4 GCM Upgrade Kit range consists of engineered and compliant suspension solutions developed to support increased combined vehicle and trailer mass.
Each GCM Upgrade Kit includes:
Each kit is engineered as a complete system, with all components matched to work together for reliable performance under heavy towing conditions.
Selected Formula 4x4 GCM Upgrade Kits are available with adjustable remote reservoir shocks for drivers seeking maximum towing control and performance.
These premium kits offer improved heat management during sustained towing, adjustable damping to fine-tune ride comfort and stability, and enhanced control on highways, corrugated roads, and long-distance touring routes.
Remote reservoir GCM kits are ideal for frequent towing, touring vehicles, and demanding operating conditions.
All Formula 4x4 GCM Upgrade Kits are engineered, compliant, and legal when fitted as specified. Each kit is developed to meet applicable Australian standards and support increased combined vehicle and trailer weights while maintaining safe vehicle dynamics.
A correctly selected and professionally installed GCM Upgrade Kit helps ensure your 4WD remains compliant, predictable, and fit for purpose when towing.
A properly matched GCM upgrade ensures your 4WD performs safely and consistently when towing heavy loads.
Formula 4x4 GCM Upgrade Kits are well suited to:
Selecting the correct GCM Upgrade Kit ensures your vehicle remains capable and controlled as towing demands increase.
