If you need a 2-post lift that can handle up to 18,000 lbs., Challenger’s model 18000 is a great choice. We designed the 18000 to service heavier vehicles such as trucks and fleet vehicles. Therefore, it features low-profile 2-stage front and 2-stage rear arms for symmetric lifting capability. Stack adapters come standard. For higher-profile vehicles, 2 foot column extensions are available.
