DMW Chassis Extensions

Built to Work. 
Engineered to Last.

Whether you’re chasing more tray space, or better load distribution, a chassis extension is the ultimate way to get more from your rig. We’ve been extending chassis extensions since 2012, helping tradies, tourers, and serious 4WDers transform their vehicles into true workhorses.

Why Extend Your Chassis?

🟧 Increased Tray Space
Extra length means more room to carry tools, gear, or a full-size canopy setup without compromising weight balance.

🟧 Better Load Distribution
By pushing the axle further back, we shift the centre of gravity and reduce stress on your suspension, chassis, and rear overhang.

🟧 Perfect for Canopies & GVM Upgrades
Chassis extensions pair perfectly with GVM upgrades and full rear setups. If you're planning to run a canopy, fridge, batteries, or even a dog box—this is the platform to build on.

🟧 ADR Compliant & Engineered In-House
Every extension is engineered, certified, and built in-house at our Toowoomba workshop. It’s not just legal—it’s rock solid.

Common Extension Lengths

We offer tailored solutions depending on your platform

Options include:

300mm - 750mm Extensions – Ideal for single/dual/extra cabs running full-length trays

Inbetween Sizes Available – Built around your tray, canopy, and GVM plans
Chassis Reduction - For vehicles like the Jeep Gladiator, a 300mm chassis reduction can improve your turning circle and all around stability. We can either fit the trimmed tub back on or one of our XTR trays

The DMW Difference

We don’t outsource. Every chassis extension is cut, fabricated, welded, and painted in-house by our team of certified professionals. No shortcuts, no compromise. Just tried-and-tested Aussie quality backed by a reputation you can trust.
