79. Install the newly modified skid upper skid plate to the
upper location using the stock hardware. Special note:
Make sure to use loctite and torque to 28 ft lbs.
80. Holding the skid plate to the front cross member, care-
fully drill a 3/16” hole through the skid plate and the stock
front cross member.
81. Locate (1) 1/4” x 1” self threading bolt from hardware bag
16985NB1. Secure the skid plate to the stock cross member
using the new 1/4” x 1” self threading bolt.
82. Locate (2) front lateral compression arms. Locate (8)
PB2408 poly bushings from hardware bag 16985PL. Also,
locate (4) S10058 crush sleeves from hardware bag
16985SL. Install the new poly bushings into each end of the
new front lateral compression arms. Next, install the new
crush sleeve into the newly installed poly bushings. Special
note: Make sure to use a lithium or moly base grease
prior to inserting the new bushings and sleeves into the
new front lateral compression arms. This will increase
the life of the bushing as well as prevent squeaking.
83. Locate (2) 1/2” x 3 1/2” bolts, (4) 7/16” USS flat washers
and (2) 1/2” unitorque nuts from hardware bag 16985NB3.

sion arm to the new front lateral compression arm mount on
the newly installed sub frame using the new 1/2” x 3 1/2” bolt
and hardware. Do not tighten at this point. Repeat proce-
dure on the passenger side.
84. Working on the driver side, measure from the new later-
al compression arm mount located on the previously
installed sub frame to the center of the stock transfer case
cross member. Special note: Chevy has a variation on the
placement of the stock transfer case cross member.
Your measurement should either be 31” or 32” long.
Remember the measurement, this measurement is
needed later in the installation.
85. Locate (2) 1/2” x 3 1/2” bolts, (4) 7/16” USS flat washers
and (2) 1/2” unitorque nuts from hardware bag 16985NB3.
Also, locate (2) rear lateral compression mounts. Working on
the driver side, if the measurement that you had earlier was
31”, secure the new lateral compression arm to the new rear
lateral compression arm mount rear hole using the new 1/2”
x 3 1/2” bolt and hardware. Do not tighten at this point. If
the measurement that you had earlier was 32”, secure the
new lateral compression arm to the new rear lateral com-
pression arm mount front hole using the new 1/2” x 3 1/2”
bolt and hardware. Do not tighten at this point. Hold the
new lateral compression arm and mount up to the stock
transfer case cross member and scribe a mark on the trans-
fer case cross member where the new mount will go. Repeat
procedure on the passenger side.
86. Working on the driver side, carefully drill a 5/16” hole in
the bottom of the transfer case cross member referring to the
marks that were scribed earlier. Repeat procedure on the
passenger side.
