As I mentioned briefly in the Buyer’s Guide, for Jeeps, vans, pickup or trucks, a 3 ton floor jack should be enough. However, that’s only true for small- or mid-size vehicles. For something bigger – like a full-size pickup or SUV - a 3.5 or 4 ton floor jack will be a more reasonable purchase. It’s very important to say that you should NEVER try to lift a Jeep with a floor jack that doesn’t meet the minimum requirements, as that can lead to serious consequences.
