Module 2: Toyota LandCruiser 300 Series Suspension GVM Upgrades, Wheels & Tyres

GVM (Gross Vehicle Mass) upgrades increase the legal weight your vehicle can carry, making them essential for towing, touring, or carrying constant loads. We use ADR-compliant Lovells GVM, GCM and BTC Upgrade kits, engineered for safety, performance, and full compliance whether your vehicle is new or already registered.

Lovells 3805kg GVM Upgrade

The Landcruiser 300 3805kg GVM Upgrade is our most popular option for most travellers. This upgrade also includes an increase in GCM for both federal (pre rego) and state compliance upgrades. This upgrade will increase the ride height of the vehicle by approximately 50mm, depending on vehicle spec level and constant load.

• Toyota GVM 3280kg » Lovells GVM 3805kg
• Toyota GCM 6750kg » Lovells GCM 7300kg
• Toyota Front Axle 1630kg » Lovells Front Axle Rating 1700kg
• Toyota Rear Axle 1930kg » Lovells Rear Axle Rating 2105kg

Lovells 4205kg Platinum GVM & GCM  Upgrade

The Landcruiser 300 4205kg GVM Upgrade is for those travelling with larger vans and heavier loads. The suspension does a superb job of carrying these increased loads, but travellers can expect a stiffer ride when unladen. This upgrade also includes an increase in GCM for both federal (pre rego) and state compliance upgrades. This upgrade will increase the ride height of the vehicle by approximately 50mm, depending on vehicle spec level and constant load.

• Toyota GVM 3280kg » Lovells GVM 4205kg
• Toyota GCM 6750kg » Lovells GCM 7700kg
• Toyota Front Axle 1630kg » Lovells Front Axle 1800kg
• Toyota Rear Axle 1930kg » Lovells Rear Axle 2405kg

Note: 

• Fitted tyres must have a minimum load rating of 116 & speed rating of R. If you would like us to organise new tyres for you at the time of suspension upgrade, please ask.

ADR Compliance

As part of the GVM upgrade process on the LandCruiser 300, the vehicle’s classification changes from MC (passenger vehicle) to NB1 (light goods vehicle), which introduces new ADR requirements. One of these is the fitment of ADR compliant Category 6 side indicators to the front guards. Additionally, raising the vehicle by 50mm causes the factory reverse lights to exceed the maximum allowable height under ADR regulations. To maintain compliance, a single reverse light is installed at the rear bumper, and the factory reverse lights are covered.

State Compliance GVM & GCM Upgrade

Registered vehicles undergoing a GVM upgrade must be presented to an Authorised Inspection Station for modification approval. To proceed, the vehicle must be in roadworthy condition. Our pricing covers the entire process, including the modification application, vehicle inspection, and approval permit.

GCM UPGRADE NOW AVAILABLE: Approval has been granted under VTB-181A for the GCM to be increased on the Landcruiser 300. This is now included with the Lovells 3805kg and 4205kg GVM upgrades.

Lovells Upper Control Arms

While not required, upgraded Upper Control Arms are a popular addition.

• Stronger than OE
• Built-in caster and camber
• Improves wheel alignment
• Increases wheel travel

Airbag Man Coil Spring Helper Kit

Airbags are another popular option. These are known as a suspension helper. The bag sits inside the coil inside a protective bag. At low loads they are run at minimal pressures and do little, but at your heaviest loads they are inflated to keep your vehicle level which is important for stability, braking and steering. 

Airbag Man - Manual Control

Our Manual option simply refers to the inflation and these have two tyre style valves fitted near your trailer hitch for adjusting pressure.

Airbag Man - Onboard Control

Our Onboard Control option simply refers to the inflation and these have a dual digital gauge and dual inflation/deflation pedals. We can only offer this system to those choosing one of our drawer systems as well as our electrical system with onboard compressor. The drawers are required for mounting the gauge and pedals and the compressor drives the onboard inflation.

Roadsafe Adjustable Panhard Rod

A Panhard rod is a suspension link that provides lateral location of the axle. One end attaches to the vehicle and the other end attaches to the axle and with the ~50mm lift of a GVM upgrade the axle moves slightly to the left. An adjustable Panhard rod allows us to correct the suspension to OE alignment which can improve tyre wear and handling.
