GVM upgrade vs suspension lift? If you’re building a 4WD and you’ve proaly wondered "What's the difference?" and "Which one do I need?". At BAW, we help customers in Brisbane and beyond figure this out every single day. Some 4x4 owners just want better clearance. Others are towing 3.5T vans to Birdsville.
Here’s how to tell what’s right for your 4x4 - and what’ll actually keep you legal and safe on the road. Because not all suspension is created equal!

What’s a Suspension Lift?
A suspension lift does exactly what it says on the tin. It lifts your 4WD by replacing your springs, shocks, or both.
Why do people get them?
To fit bigger tyres
For better off-road clearance
For looks (be honest)
To improve ride quality
Suspension lifts are great for:
Weekend warriors
Beach trips and fire trails
Utes without canopy setups
But here’s the catch: Suspension lifts do not legally increase how much weight your 4x4 or ute can carry. That’s where most people get caught out.

What’s a GVM Upgrade?
A GVM (Gross Vehicle Mass) upgrade increases your vehicle’s legal carrying capacity. It’s a certified suspension system that’s tested and approved to carry more weight.
Why do you need one?
Yes, if you’re constantly running heavy. Most people don’t realise how close they are to the limit. A full canopy setup, tools, drawers with a fridge, long-range fuel tank… it all adds up.
A GVM upgrade is only necessary when you’re pushing your 4WD beyond what the factory allows.. If you’re touring full-time, towing a big van, or running loaded every day, you’re the kind of owner who needs it. Suspension alone won’t make you legal. GVM is what keeps you compliant, safe, and covered by insurance.
GVM upgrades are for:
Towing heavy 3500kg caravans or boats
Tradies with full tool setups
Anyone carrying constant loads
