About Us
About Us – Relentless Chassis
Precision. Strength. Style.
At Relentless Chassis, we don’t just make parts — we build solutions. Based on the Gold Coast, we specialise in 4-link rear conversions, chassis notches, independent front-end swaps, CNC cutting, and full custom chassis work for trucks, utes, classics, and custom builds. Every cut, weld, and bracket is done with purpose, so your ride sits lower, drives better, and looks tougher.
Our Story
Relentless Chassis was born out of a passion for building tough cars and the demand for suspension setups that are smarter, stronger, and engineered to last.
What began in a shed with a welder and a vision has grown into a trusted workshop where tidy welds, CAD-designed geometry, CNC precision, and engineered outcomes set the standard. We’ve built our reputation on work that doesn’t just look good — it performs.
Today, we deliver chassis and suspension solutions that provide stance, strength, and safety without compromise.
