The AUTOACER Complete Lift Kit comprises four polyurethane spacers, designed to provide a lift of 40mm (approximately 1.6 inches) for both the front strut and rear coil springs of vehicles and 6 accompanying bolts, fits Highlander (model years 2000-2013), Harrier (model years 2003-2013), and Kluger (model years 2000-2013). These spacers are constructed from high-grade polyurethane (PU), a durable and flexible material known for its resistance to wear, tear, and environmental elements. This kit is designed to enhance the ground clearance of the aforementioned vehicle models, allowing for increased height between the chassis and the ground. This lift can be beneficial for various purposes, including off-road driving, accommodating larger tires, and improving the vehicle's overall appearance. By installing the front strut and rear coil spring spacers, the suspension geometry of the vehicle is adjusted, resulting in the desired lift. The front strut spacers are positioned above the front struts, while the rear coil spring spacers are inserted between the coils of the rear suspension springs. This alteration provides the lift without compromising the vehicle's handling or ride quality. Polyurethane is chosen as the material for the spacers due to its durability and resilience, which ensures a prolonged lifespan even under demanding conditions. The polyurethane construction also helps in minimizing noise and vibrations commonly associated with such modifications.
