Illinois lift laws?

[Gage2502]

Ok so im about to buy an 4" lift kit for my 2005 Super Duty and now I find out that the law says you can only lift it 3"?
Heres the law.
"Suspension Lifts (§625-5/12-607): "It shall be unlawful to operate a motor vehicle on any highway of this State when the suspension system has been modified from the original manufactured design by lifting the body from the chassis in excess of 3 inches or to cause the horizontal line from the front to the rear bumper to vary over 3 inches in height when measured from a level surface of the highway to the lower edge of the bumper ..."

It say by lifting the body from the chassis? I would be lifting the chassis from the axles. Is this the same thing?

There are two kinds of lifts. Body lifts and suspension lifts.

Lifting the body from the chassis would be a body lift. However none are made for diesels.


Now that being said they meant you cannot lift it more than 3 inches taller than stock


(Lawmakers are not suspension gurus)

No that also being said I see trucks alot taller than that driving through IL every day

That law has nothing to do with a suspension lift. The only things you have to worry about here are frame and bumper height. The law for a 3/4 or 1 ton truck is frame hight can not excede 30" at the lowest point between the wheels. Front bumper 28" to the lowest point and rear bumper 30". You can NOT run any kind of bumper or frame extension device. Failure to comply with these are a class C Misdemeanor in this state.

I have a 03 F350 8in lift with 37X13.5 tires. Iv had it for 5 years now running from South Suburbs to central IL to southern IL heavily the last few years and even many trips to northern Minnesota, south western Michigan and also every year to West Virginia. Iv been stopped once and given a warning. Don't speed or get stopped for other violations and you'll be ok...for now. Law has been changing the last few years...you once could have your tires stick beyond wells up to 3 inches, not anymore. Body lifts are now illegal where 3in was once the limit. As for bumper heights there has always been revisions based on GVW... not anymore it 3in over stock bottom line. I would just get a 3in your not gonna notice the difference trust me. My tires loose that much thread in thread though its life haha! Also mud flaps are a requirement on ALL trucks. A lot of "dumb" laws that make your truck look like ****.

Your statement is incorrect. You might try reading the actual IL Vehicle Codes
Chapter 12 article VI has the laws regarding lift kits. The 3 that are most relevent are
12-607, 12-607.1 and 12-608
