A renewed item that pursues a comfortable ride. The "Bump & Reverp Stopper" is an essential item for lowering the high ace. In the state of a significant down from the standard car height, the suspension stroke width has been extremely reduced. If you leave a stroke, the tire will interfere with the wheel house at the bump, or the rebound will cause the car to come up in a very unstable and dangerous. The rear side also causes a problem of hosing touching the floor. Thats why the improved "stroke stopper" has arrived. Developed with a different idea than conventional products, this item is made of special silicone rubber that allows you to reduce stroke speed while absorbing impact. 3mm / 5mm / 7mm adjustment plate is included for you to choose the setting height, and 7 patterns can be adjusted from 3mm to 15mm. In addition, when used with the RC Joint that reduces the roll and improves riding comfort, it will evolve into an invincible stylish vehicle. Please check the manufacturers website for more details.
