Tough Dog Coil Springs

High Performance Coil Springs for 4WD Vehicles

At Opposite Lock Cardiff, we know that great suspension makes or breaks an adventure, so we stock Tough Dog Coil Springs built tough for Australian tracks. Whether you are cruising the steep ridges of Hunter Valley or running the weekday commute between Newcastle and Port Stephens, these coils give your 4WD a smooth ride and extra strength, no matter the load.

Crafted from premium German X5K spring steel, every set balances brute strength with the flex required to soak up bumps and keep axles aligned. Rigorous testing means the springs hold their shape underweight, so you enjoy consistent handling whether the boot is full or the route turns rocky.

Tough Dog Suspension Coil Springs: Engineered for Superior 4WD Performance

Designed and built in Australia, Tough Dog Coil Springs are made to shrug off salt, stones, and the kind of corrugations that break average steel. By choosing high-tensile German X5K wire, the engineers trim stray grams from each coil while boosting overall toughness. Hot forming, shot peening, scragging, load testing, and a baked powder finish together lock in memory, strength, and long-lasting rust protection, and they stand behind that work with an industry-leading 4-year unlimited-kilometre guarantee.
