Lift Kits

$200–$3,000 parts

Install: $300–$1,200 DIY: "Somewhat challenging, like a small hill to climb." Popularity: 55%

Body or suspension lift kits raise ride height for larger tires, more ground clearance, and an aggressive stance. Leveling kits are a smaller, cheaper first step than a full lift.
