Will it fit?

Pure geometry — diameter delta, speedometer error, offset shift, hub bore, bolt pattern, lift estimate. Edit a field; the verdict updates live. Bumpstop clearance and fender-liner intrusion aren't in this list because they aren't deterministic math.

Geometry only — clearance with bumpstops, fender-liner, and sway-bar depends on shock travel and chassis flex, none of which is in any spec sheet. If a verified build report disagrees with this page, trust the report.
