What are the maximum legal lift heights allowed in Tennessee?

Tennessee law limits how high you can lift your vehicle's suspension or body. The maximum height depends on the type of vehicle and the measurement method used.

Height limits ensure lifted vehicles remain safe and stable on roads. You must measure from the ground to the highest point of the vehicle's body or frame to check compliance.

• Truck and SUV rules: Trucks and SUVs follow the same 6-inch lift limit unless classified as off-road vehicles not used on public roads.

Exceeding these limits may require additional inspections or special permits. Always check local regulations as some counties may have stricter rules.

How does Tennessee law define a lift kit?

Tennessee law defines a lift kit as any modification that raises the vehicle’s suspension or body above the manufacturer’s original height. This includes suspension lifts, body lifts, and tire size increases.
