Although the same basic frame was used on all Chevy and GMC pickups and SUVs from 1987-2002, slight frame variations require different baseplates to accommodate all of these vehicles. Roadmaster has the following guide to determine the correct fit for your vehicle.

For 87-98 Chevy and GMC trucks and SUVs: 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 and may run from front to back or from side to side. See CHART 1 and IMAGE 1 to determine the correct baseplate.

For 99 and newer Chevy and GMC trucks and SUVs: If the tow hooks are bolted externally to the bottom of the frame, use the instructions above for the 87-98 Chevy and GMC trucks and SUVs. If the tow hooks are bolted internally in the frame rail, use CHART 2 to determine the correct baseplate.

FOR ½ TON 2 WHEEL DRIVE ONLY: Check front suspension for torsion bar or coil spring. If you have a torsion bar, use kit 199-1 or 199-3. If you have a coil spring, use 199-8. FOR ¾ TON 2 WHEEL DRIVE with torsion bar, use # 3101-1.
