Lift height
How much a kit raises the body away from the axles, measured in inches; primarily controls tire clearance.
Lift height is the vertical distance a kit raises the vehicle body off its axles, almost always quoted in inches (even outside the US). The relationship between lift and tire clearance is roughly linear up to about 3″, beyond which CV angles, differential geometry, and steering component limits start fighting back.
Typical brackets: - 0–1″: leveling kit, fixes factory front-rear rake. Clears stock tires + maybe one size up. - 2–2.5″: most common bolt-on kit. Clears 33s on most mid-size 4×4s. - 3″: needs adjustable upper control arms on IFS platforms; clears 35s with light fender trimming. - 4″+: requires drop brackets, extended brake lines, and either drive-shaft work or carrier-bearing relocation. Beyond 4″ the kit is practically a long-arm conversion.
A "lifted ceiling" — the largest tire diameter the chassis clears with a typical lift — is in the FitsMyRig database for every chassis. For a 2018 Toyota Tacoma it's about 33″.
