All vehicle specs →Every input lives in the link, so you can send a result to a buddy or drop it in a forum thread. The presets come from factory spec sheets; anything we couldn't confirm against one says so when you pick the truck. Something wrong for your rig? Tell us. Looking for printable clips and brackets instead? That's Free Parts.
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.
