FYI the COMAR suggests that lift kits and suspension modifications are authorized. Don't listen to a cop that says any suspension modification is illegal. That is complete nonsense. Only major no go's are a non functional suspension, vehicle frame height too high, bumpers too high, fenders not covering top of wheels all the way down to the wheel center line.
Here the COMAR specifically references lift kits and the wording suggests they are authorized as long as they meet certain requirements:
(6) Springs and Torsion Bars. Loose, sagging, or broken springs or torsion bars, worn or deteriorated bushings, loose or extended shackles and loose or mislocated U-bolts, suspension modifications or broken center bolts, can cause vehicle handling instability and brake pull.
Procedures: Reject Vehicle If: (a) Springs and Torsion Bars. With unloaded vehicle on level surface, visually inspect the heights of the four corners of the vehicle. If necessary, use measuring device and determine differences from side to side. Visually inspect for broken spring leaves or torsion bar damage. Inspect spring shackles, bushings and U-bolts. Visually inspect for presence and condition of lift kits, blocks or modification to the suspension system or components. (a) Spring, spring center bolt, or torsion bar is broken, or if more than two spacers have been installed in coil springs or are loose. Lift kits are installed and this installation results in multiple blocks being used as a means of raising the vehicle; or there is any evidence of looseness of any lift kit or suspension components. The lift kits do not provide a means of aligning the spring center bolt, Spring and axle or axle housing. Shackles or U-bolts worn, loose, or extended causing misalignment of steering linkage or drive line angles, U-bolts are not of sufficient length protrude at least 1/4 beyond nut when tightened.
