Ford Bronco
2-door, 2021–
Factory gearing, tires, angles and brakes for the Bronco, and what the usual upgrades do to it. Every number is from the maker's own figures unless the calculators say otherwise. A few figures here are still waiting on a factory document; the calculators mark them.

Every calculator, set up for the Bronco
Source: fromtheroad.ford.com. Ford fits a welded ring gear to the 3.73 and 7-speed manual carriers, so regearing those takes a new carrier.
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. Long Range Desert Tools is not liable for anything you do based on these calculators or their results. The full terms are in our policies.
