Search “lift kit laws Mississippi” and you will get a confident answer in about four seconds: eight inches of total lift, six inches of it from the suspension. It shows up on national aftermarket retail blogs, on dealer sites, and in forum posts quoting other forum posts.
Here is the problem. That number is not in the Mississippi Code.
We install lift kits for truck owners all over Hancock County, from Waveland and Bay St. Louis out to Kiln and Diamondhead, and this is the question that comes up in our bay more than almost any other. So we went and read the actual statutes instead of the blogs. What we found is a set of rules that is narrower than most people expect in one place and broader in another, and knowing the difference is what keeps a nice truck out of a traffic stop on Highway 90.
The short version:
- Mississippi sets no maximum lift height in inches.
- It does ban a four-inch front-to-rear fender gap, and that rule has teeth right now.
- Overall height and reflector height rules still apply to your build.
- Headlight aim, tire load rating and tow geometry are the shop’s job after the kit goes on.
Lift Kit Laws in Mississippi: The Number Everyone Repeats, and Where It Comes From
Mississippi does not have a statute that sets a maximum lift height in inches. There is no section of the code saying your suspension may rise six inches and no more, or that your total lift including tires is capped at eight.
We are not saying a big lift is automatically fine. We are saying the figure people quote at each other has no statutory home, and if you plan your build around it you can still end up illegal for reasons that number never mentions.
What Mississippi does have is three things worth knowing:
- One statute written specifically for modified trucks, and it measures front-to-rear stance, not height.
- A general vehicle height cap that applies to everything on the road.
- Equipment rules on lighting and reflectors that a tall build genuinely can violate.
Take those three together and you have the real envelope for lifted truck legal height in Mississippi. Let’s go through them.
The One Rule Written for Modified Trucks: Section 63-7-105
In the 2024 Regular Session, the Mississippi Legislature passed House Bill 349, introduced by Representatives Shanks, Tullos and Felsher. It created a brand-new section of the code, Section 63-7-105, and it is the only place in Mississippi law that addresses truck suspension modification head-on.
The operative language is short. It is unlawful to drive a passenger motor vehicle on the streets or highways of this state if, by alteration of the suspension, frame or chassis, the height of the front fender is raised four or more inches greater than the height of the rear fender.
Read that again, because the important word is fender, and the important comparison is front against rear.
How the state measures it
The statute does not leave the measurement to interpretation. It says the height of the fender is a vertical measurement from, and perpendicular to, the ground, through the centerline of the wheel, and to the bottom of the fender. “Fender” gets a definition too: the pressed and formed part mounted over the road wheels to reduce the splashing of mud, water or similar substances.
So an officer is not eyeballing your bed rail or your roofline. Ground, straight up through the middle of the wheel, to the bottom edge of the fender. Front number, rear number, subtract.
What the law is aiming at
The statute defines “squatted vehicles” as vehicles whose front fenders have been raised four or more inches greater than the rear fenders, which makes the truck look like it is squatting on its back tires. That stance, sometimes called the Carolina squat, is what HB 349 was written to stop.
The exemption most people miss
There is a written carve-out. Motor vehicles equipped with high clearance fenders to allow for increased front suspension articulation are exempt from the prohibition. That matters for real off-road builds where the fender is cut or replaced to let the front suspension travel, rather than to strike a pose. If your truck is in that category, bring it by our Waveland shop and let us see how it measures.
The enforcement timeline
HB 349 took effect on July 1, 2024. For the first 180 days, state and local officers issued warning tickets only. From and after January 27, 2025, officers issue tickets that assess penalties.
We are well past that date now. The grace period is over, and it is over for Hancock County deputies and Waveland police the same as anywhere else in the state.
A violation is a misdemeanor. The fine escalates on a second offense and again on a third, and a third or subsequent conviction also carries a twelve-month license suspension by the Commissioner of Public Safety. Only offenses occurring within five years of each other count as priors. Fines collected go into the State General Fund and are used to help fund secondary school driver education programs.
We are deliberately not printing fine amounts here, and we are not going to guess at what a stop costs you in the end. What we will tell you is that the cheapest version of this is measuring the truck before it goes back on the road.
Why It Is a Differential, Not a Height Limit
This is the part that trips up good, careful truck owners.
Because Section 63-7-105 compares your front fender to your rear fender, a level lift is not what the statute is aimed at. Put a six-inch kit under a half-ton in Waveland, keep the truck sitting level front to rear, and the kit itself is not what makes the truck illegal. There is no inch figure in the code for it to violate.
Flip it around and the point gets sharper. A truck with a modest three-inch front kit, stock rear springs and a few years of load in the bed can drift toward that four-inch gap without the owner ever thinking the word “squat.” The statute measures the gap. It does not care what you meant by it.
Pro tip: if you haul or tow regularly and your rear has settled, measure your fenders before you add anything at all to the front. Rear sag plus a modest leveling kit can walk you across the line from two directions at once.
The good news? This is a five-minute measurement on a level floor, and it is a normal part of any lift kit installation in Waveland MS that is done properly. If you are looking for a truck shop near you to check a stance you are unsure about, that is the check to ask for by name.
The Height Rules That Still Apply to a Lifted Truck in Mississippi
Two more sections of the code are worth having in your head.
Overall height, Section 63-5-17. No vehicle, unladen or with load, may exceed a height of thirteen feet, six inches. The same section adds a clause that ought to concentrate the mind: nobody, including the state, is required to raise or reconstruct any underpass, wire, pole or trestle to let a vehicle taller than twelve feet, six inches pass, and full liability for damage to that structure falls entirely on the operator.
Most lifted pickups are nowhere near thirteen-six. Fleet trucks with racks, service bodies, ladder cages or a camper shell stacked on top of a lift are a different conversation, and so are the older low-clearance crossings and canopy roads you will meet between Kiln and Pass Christian.
Reflectors, Section 63-7-29. No reflector required by the chapter may be mounted higher than sixty inches above the ground, or lower than twenty-four inches. Reflectors also have to be readily visible at night from five hundred feet down to fifty feet in front of a normal headlight beam.
This is the one that quietly catches people. Reflectors move up with the body. A tall build can put a factory-located reflector above that sixty-inch ceiling, and nobody thinks about it on install day, because it is not a “lift” rule, it is a lighting rule. It is still a violation.
What the Shop Re-Checks After the Kit Goes On
Staying legal is the floor, not the finish line. Once the kit is torqued down, the truck is a different vehicle than the one the factory certified, and three things need looking at again.
Headlight aim
Mississippi’s Section 63-7-31 requires your upper beam to be so aimed that it reveals persons and vehicles at least three hundred fifty feet ahead, and your lower beam to be so aimed that it reveals them at least one hundred feet ahead. The word doing the work in both sentences is aimed.
At the federal level, FMVSS No. 108 requires lamps and reflective devices to be installed so their photometric requirements are met and so no other part of the vehicle prevents that, and it spells out aimability performance requirements. What the standard does not do, according to NHTSA’s own interpretation letters, is prescribe the initial or subsequent aim of a headlamp on a vehicle modified after it left the factory.
Translation: nothing about your lift kit re-aims your headlights for you. Raise the front of a truck and the beams go up with it, which is how a well-built truck ends up blinding oncoming traffic on Highway 90 after dark. Re-aiming is a shop step, and it is on us.
Tire load rating
This is the one with real liability behind it. The rule the tire industry works to is simple: the replacement tire must meet or exceed the original equipment tire’s load-carrying capacity.
Lifts create fender clearance, clearance invites a wider and taller tire, and a wider, taller tire very often carries a lower load index than the one it replaced. Tire Review walked through a case where swapping a factory P265/70R17 with a 113 load index for a P275/55R20 rated 111 left the vehicle overloaded by one hundred thirty-two pounds per tire, five hundred twenty-eight pounds across the truck. The same piece notes that a single tire size can carry as many as five different load index numbers, so reading the size off the sidewall tells you almost nothing.
Load rating is the same homework we do before any new wheel and tire package goes on a truck, and it is the step most likely to get skipped when a lift is bought online and bolted on in a driveway.
If your truck tows a boat down to the Bay St. Louis ramp on Saturdays or carries tools all week for a Hancock County crew, that margin is not theoretical. We check the load index against the door-jamb placard, every time.
Tow and driveline geometry
Lifting the truck rotates the pinion angle, raises the hitch and changes how a trailer sits behind you. A trailer that rode level before the kit will nose down or tail down after it, which moves weight off the axle you want it on and changes how the whole rig behaves under braking.
The fixes are ordinary: a corrected hitch drop, a driveshaft or pinion angle correction, sometimes a rethink of which tire goes under the truck. They are only ordinary if somebody checks. If you run work trucks or a small fleet along the coast, this is worth building into your regular service routine rather than discovering it on a loaded trailer.
Lift Kit Installation in Waveland MS, Done Inside the Law
None of the above requires a lawyer. It requires a tape measure, a level floor, someone who has actually read Section 63-7-105 rather than a blog summary of it, and a shop that treats headlight aim and load rating as part of the job instead of an upsell.
We handle lift kit installation in Waveland MS for customers across Bay St. Louis, Kiln, Pass Christian, Diamondhead and the rest of Hancock County, and we measure fender heights front and rear before the truck goes back on the road.
On cost: parts and labor move too fast for a blog post to give you an honest number, and a lift is not a one-size job anyway. Kit brand, ride height, tire and wheel package, and whether your truck needs geometry correction all change the answer. Ask us for a current quote and you will get a real one for your truck, not a range that went stale the day it was published.
Thinking about lifting your truck, or already running one and not sure where it measures? Schedule an appointment at our Waveland shop and we will put a tape on it, check your fender differential against the statute, and tell you straight what it needs.
