Question

What lift height is this for?

Suspension lift height

This is a 2.5-3 inch lift-height family. Verify the exact engine, drive side, spring-capacity variant, and loaded vehicle weight before quoting because those choices can change final stance.

For a lift, the last check is the complete Jeep setup: exact year/model/trim, doors, engine, lift variant, target tire size, wheel width and offset/backspacing, bump stops, flare/fender clearance, gearing, spare support, added bumper/cargo weight, and whether a shop is installing it.
