NZ's best bounce!

MEGA-Air spring dynamics

Experience the ultimate bounce with high-performance piano wire springs! Designed for higher, smoother jumps, they stretch further, storing more energy for a controlled, effortless takeoff and landing—reducing impact on your joints. Crafted from high-tensile, high-carbon steel, these springs resist fatigue and deformation, ensuring long-lasting durability.
