QUALITY POLICY

Tough Dog Suspension (4Way Suspension Products Pty Ltd) is committed to engineering, manufacturing and supplying quality 4WD suspension products that meet Australian Design Rules and customer expectations across more than 55 countries.

Our quality objectives include:

• Continuous improvement through annual management review

• Ongoing investment in engineering and testing capability

• Rigorous incoming inspection of critical components

• Regular review of warranty data and field reports to drive product refinement

• Maintaining compliance with applicable Australian Design Rules and relevant ISO standards

Every Tough Dog product undergoes dyno testing, road testing on Australian conditions, salt spray corrosion testing, fatigue cycle testing, and high/low temperature testing before production release.

Our Marsden Park facility includes a full dyno lab, heat cycle test rig, and in-house metallurgical testing capabilities.

We require all component suppliers to hold ISO 9001 certification or demonstrate equivalent quality management practices. Critical components are subject to incoming inspection.

Our Australian steel supply chain is documented and audited annually.

We use customer feedback, warranty data, and field reports to drive continuous product improvement. Our engineering team reviews all warranty claims monthly and feeds findings into our product development process.

All Tough Dog products are designed and manufactured in compliance with applicable Australian Design Rules (ADRs), NCOP standards where relevant, and relevant ISO standards for automotive components.
