Ford E-Series
4x4 conversions, 1992–

Every calculator, set up for the E-Series
Source: legacy.sportsmobile.com. Quigley, Sportsmobile and U-Joint builds differ. Read your transfer case tag and axle tags before trusting these figures.
Use at your own risk. These calculators are here to help you plan and to inform your decisions, not to sign off on a build. Many numbers are estimates worked out from factory figures, and some factory figures are not yet confirmed. Check every number against your own truck, its manuals and a qualified shop before you buy parts, cut, weld, lift, regear or drive on it.
