Built from reinforced ABS plastic, stainless steel hardware, and high-strength polyester webbing, it locks securely into most standard buckles and maintains full restraint performance for daily commutes and long road trips alike.

Designed for Real-World Driving
Every component is engineered to withstand the rigors of daily automotive use. The reinforced ABS buckle housing resists impact and temperature extremes, while the stainless steel latch tongue prevents corrosion and ensures a positive click every time. The 2-inch-wide polyester webbing distributes load evenly, reducing pressure points during sudden stops. Because the extension works with tongue widths of 0.79 or 0.87 inches and lengths up to 1.2 inches, it fits the majority of domestic and imported vehicles—just verify your buckle dimensions before ordering. Ships free within the US, backed by a 30-day return policy so you can test fit with confidence.
