Premium Quality: Our steering wheel swivel is made of high-quality silicone materials to ensure maximum durability and flexibility. It features a sturdy metal bearing that rotates smoothly 360 degrees, allowing for effortless rotation and convenient one-handed driving. The soft silicone provides a comfortable feel and will not damage the steering wheel. Quick Installation: Easy to install and securely fastened to prevent loosening. First, separate the square clips of the booster. Install the inner layer onto the steering wheel, then clip the booster body onto the inner layer and adjust to the desired angle. If the steering wheel has a cover, remove it before installation. The knob material will not harm your hands or the steering wheel. Compatibility: The steering wheel knob measures 8.5 x 5.5 cm. The universal design fits most steering wheels. Ideal for use during reversing, turning, and parking. For safety, use only at speeds under 20 km/h. Always ensure the booster is securely attached before driving. Ergonomic Design: The spherical shape fits naturally in the palm, offering a comfortable grip and helping reduce driving fatigue, shoulder strain, and back pain. The 360-degree rotating bearing ensures even force distribution, reduces steering resistance, and enhances driving comfort during long trips. Package Includes: 1 x Steering Wheel Booster Ball.
