Design Height Measurement

1. Place vehicle on a level, flat surface such as an alignment rack or drive-on lift that will allow access to underside of vehicle. Check that all tires are at specified inflation pressure. Adjust pressure as necessary.
NOTE: When loosening lower control arm mounting bolts, be sure alignment adjustment cams do not turn. The cams must stay in their original position so alignment of vehicle is not affected.
2. Loosen mounting bolts for following suspension components:
   • Front and rear lower control arm to frame bracket mounting bolts.
   • Front and rear upper control arm to frame bracket mounting bolts.
   • Front upper control arm to pivot bar mounting bolts.
   • Front and rear shock assembly to frame bracket mounting bolts.
   • Front and rear shock assembly to lower control arm mounting bolts.
     NOTE: The mounting bolts must be loosened enough to allow suspension of vehicle to move without loading (twisting) rubber insert of isolator bushings.

If vehicle is equipped with BBS racing wheels (ACR suspension option), proceed to BBS WHEEL HEIGHT GAGE ADAPTER INSTALLATION (ACR)  . Otherwise, proceed directly to MEASUREMENT PROCEDURE  under BBS WHEEL HEIGHT GAGE ADAPTER INSTALLATION (ACR).
