Increase the load carrying capacity of your vehicle with a Lovells GVM / GCM Upgrade. Whether it’s for work or for off-road touring, many four-wheel drive owners often need to load up their rigs – and doing so can quickly exceed a vehicle's legal Gross Vehicle Mass (GVM) and Gross Combination Mass (GCM). Lovells GVM / GCM Upgrades allow vehicle owners to carry more gear safely and comfortably in any situation, whilst staying on the right side of the law and without voiding your vehicle insurance.
