Note 36

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 87-98 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 99 & NEWER CHEVY & GMC TRUCKS & SUV’S: If the tow hooks are bolted externally to the bottom of the frame, use the instructions above for the 87-98 Chevy & GMC trucks & SUV’s. If the tow hooks are bolted internally in the frame rail, use Chart 2 to determine the correct bracket.

FOR ½ TON 2 WHEEL DRIVE ONLY: Check front suspension for torsion bar or coil spring. If you have torsion bar, use kit 199-1 XL or 199-3 MX. If you have a coil spring, use 199-8 XL (199-9 MX Discontinued).

FOR ¾ TON 2 WHEEL DRIVE: with torsion bar, use 3101-1.		 Frame Measurement
