Make your Isuzu D-MAX Gen 3 MY21+ safer and easier to use with the HSP Tailgate Assist - a premium dual or single strut system (depending on ute) designed to control the drop of your tailgate and reduce lifting effort. Engineered in Australia for Australian conditions, the HSP Tail Assist uses a combination of a hydraulic dampener (for soft-open) and a gas strut (for lift assist) to give smooth, controlled operation every time.
Perfect for anyone loading gear daily, families, tradies, and anyone wanting a safer, lighter tailgate experience.
