Will this KYB shock fit a lifted or lowered vehicle?
Only if the exact part number is specified for that ride height. Confirm extended length, compressed length, mounting style, suspension travel, and every application note.
What should be inspected while replacing the shock?
Inspect mounts, bushings, bump stops, boots, springs, fasteners, tires, and related suspension joints. Correct worn or damaged parts before alignment and road testing.
