Tough Dog Front Coil Springs (Wrangler JK) 40mm Lift

Tough Dog coil springs are designed and manufactured in Australia to exacting standards to stand up to some of the harshest conditions found anywhere in the world.

Made from German X5K spring steel, our coils can be designed with less material while maintaining superior ride quality & load carrying characteristics. The spring retains its original memory even after heavy loading. The result? A lighter, tougher coil that can handle just about anything you can throw at it.

• Shot peened to relieve stress
• Scragged and load tested
• Formed on precision mandrels
• Hot formed to maintain spring memory
• Powder-coated for looks and corrosion resistance
