Is it legal to lift your vehicle?

Yes, while regulations vary from state to state and in some non-domestic regions, you are well within the law to drive a lifted vehicle on the road. The laws that are in place are for safety of you and other motorists on the road. All BDS lift kits are designed with safety involved, heavy duty components, bracing, suspension and steering geometry correction along with ESC system compatibility to ensure your vehicle will perform up to safety standards on the road. It is best to check with rules & regulations in your state, some have limitations based on bumper heights, headlight height, the distance tires can extend beyond the fender, requirements for steering components (ie no welded/fabricated parts or full hydraulic), beadlock wheels, retaining OE equipment like sway bars and other regulations that some states require.
