This Jeep Wrangler YJ suspension remains largely stock except for the addition of a set of extended shackles. Extended shackles are a cheap and easy way to lift a 4x4 with a leaf spring suspension. Be careful how tall you go with a shackle lift as steering and handling get worse as you go. This is a reasonable degree of lift shown on this YJ, enough to fit 33-inch tires. Remember, a shackle lift is still a lift and can require additional suspension, steering and drivetrain modifications in order to operate most efficiently.
