Chevrolet - GMC 1987-2002

Although the same basic frame was used on all Chevy & GMC pickups & SUV’s from 1987-2000, slight frame variations require different brackets to accommodate all of these vehicles. Carefully read the following to determine the correct bracket:

FOR 1987 - 1998 CHEVY & GMC TRUCKS & SUV’S: Measure the distance from point A (on the bottom of the frame) to point B (on the side of the frame). The hole on the bottom of the frame is slotted & may run from front to back or from side to side. See Chart 1 to determine the correct bracket. (See Image 1, right).

For 1999 - 2002 CHEVY & GMC TRUCKS & SUV’S: If the tow hooks are bolted externally to the bottom of the frame, use the instructions above. If the tow hooks are bolted internally to the frame rail, use Chart 2 to determine the correct baseplate. Check front suspension for torsion bar or coil springs. If upi jave a torsion bar: Use kit 199-1 or 199-3 (4WD only) for 1/2 tone models and 3101-1 of 3/4 ton models. If you have coil aprings: Roadmaster does not have a fit.
