    I have a 6 inch lift on an 87 v1500 SB. I really don't want to buy new springs for the front. But to get it inspected, I need to get it back to stock height. The rear has a 6 inch block, I can knock that out and I think it will be near stock height, but the front has a nine leaf spring. Could I remove several leafs to have the front end near stock height?

    Current Maine Laws do not have an issue with your front lift AFAIK. The rear blocks are another issue. Here is the laws ftp://ftp.maine.gov/pub/sos/cec/rcn/apa/16/222/222c001.doc

    §10.5.1 Frame height limits are based on the gross vehicle weight rating of the vehicle or the gross vehicle weight rating of the vehicle providing the majority of the running gear. Heavy duty springs will not be considered to increase the gross vehicle weight rating over the manufacturer’s original rating.

    §10.5.2 Door height limits will be based on the door height as the vehicle was originally manufactured or based on the standards for the door height as manufactured for the vehicle providing the majority of the running gear.

    §10.5.3 All measurements for the bottom of the driver’s door will be made on a level surface with the vehicle unladen. All tires must be inflated to the manufacturer’s recommended tire pressure. The doors must be in the original manufactured location. Vehicles manufactured without doors shall be measured from the lowest point on the floor panel directly below the operator’s position.

    §10.5.4 Frame end measurement shall be taken when the vehicle is parked on a level surface with the vehicle unladen. All tires must be inflated to the manufacturer’s recommended tire pressure. Measurements shall be to the bottom edge of the original manufacturer’s frame rail, at the end where the bumper brackets attach. Any frame component or sub-frames added to the vehicle after original manufacture shall be disregarded for frame height requirements.

    §10.5.5 Maximum frame end heights are established by 29-A MRSA §1920 and are restated below.

    §10.5.7 Vehicles equipped with an anti-lock brake system may not be altered.

    §10.5.8 Any vehicle where the vehicle height has been altered in any way shall be closely inspected as to any part that may be stressed by the alteration. In particular, the following items shall be examined:

    §10.5.10 If the rim size has been altered, the overall diameter of the wheel with the tire must be within the manufacturer’s specifications. If, in the opinion of the inspection mechanic, there is insufficient tire sidewall to permit safe operation of the vehicle, no sticker may be issued.

    I can't believe that Maine has some of the toughest laws in the Union.....Michigan...(motor state) has some of the lackest laws (yeh).
    I have some family that lives in Maine, and they're always complaining about the certification.

    I didnt read all the regs. so this may have been covered. Why not try a axel flip for the front, put the axel on top of the springs. This should lower it about six inches. After inspection flip it back. Also I guess you would take out the blocks too.
