Since most dedicated trail rigs use solid axles, here’s a shot of the Kwik Jak HD lifting one. Officially speaking, the Kwik Jak HD is only intended to lift and lower the vehicle. If you need to crawl underneath for any wrenching, you should place a jack stand to support the vehicle’s weight. The Kwik Jak HD’s lifting capacity is 2,500 pounds, and we found that the first two lift stages are more powerful than the third. If you extend the lifting saddle you’ll need less of the third stage. This is a non-issue for compact trail rigs, but our fourth-generation 4Runner is no lightweight. Each 20-ounce bottle returns about four lifts. We keep a secondary jack in the 4Runner, but reach for the Kwik Jack HD first.
