STEP 1—PREPARE THE VEHICLE

Place the truck on a solid level surface. Remove the negative

battery cable. Take necessary safety precautions such as using

wheel chocks when working on your truck.

On some 2008 and newer trucks some lines must be reposi-

tioned on the left side of the vehicle. Remove the nut holding the

fuel line retaining clip. Rotate the retaining clip 90 degrees with

the stud facing down. Install the relocation bracket with the nut

previously removed. Next fasten the retaining clip to the reloca-

tion bracket using a 5/16"-24 x ¾" bolt and 5/16"-24 flange nut.

Your truck is equipped with jounce bumpers attached to

the frame directly above the axle. Remove these bumpers by

unbolting from the inside of the frame flange. These bumpers

will not be re-used with this kit. For vehicles from 1999 to 2004

please save the collar as it will be re-used in Step 2B.

STEP 2A—UPPER BRACKET INSTALLATION FOR

2008 AND UP TRUCKS

Insert the 3/8"-16 x 2-1/2" flat head bolt into the upper bracket

and then slide the spacer over the bolt. Install the upper bracket

onto the frame. Make sure that no part of the vehicle’s wiring

will be pinched between the upper bracket and the frame.

Tighten the 3/8"-16 flat head bolt with a 3/8" large flat washer

and 3/8"-16 flange nut. The emergency brake cable will have

to be tie-wrapped out of the way using the hole provided in the

upper bracket. See Figure “A”.

On trucks without factory installed in-bed hitch, install the

¾"-16 x 3" hex bolt through the existing hole in the frame rail and

upper bracket. Secure the ¾"-16 x 3" bolt with a ¾" flat washer,

¾" lock washer and a ¾"-16 hex nut.

On truck with a factory installed in-bed hitch, install the ¾"-16

x 1-3/4" hex bolt through the existing hole in the frame rail and

upper bracket. Secure the ¾"-16 x 1-34" bolt with a ¾" thick flat

washer, ¾" lock washer and a ¾"-16 fame nut.

STEP 2B—UPPER BRACKET INSTALLATION FOR

1999 TO 2004 TRUCKS

Make sure that no part of the vehicle’s wiring will be pinched

between the upper bracket and the frame. At this time, the collar

that was on the jounce bumper will be reused. Insert the collar

into the original hole on the frame. Put the upper bracket in place

(to hold the collar) while you insert the 3/8"-16 x 2-1/2" flat head

bolt into the upper bracket and collar. See Figure “B”. Secure

the 3/8"-16 flat head bolt with a 3/8” large flat washer and 3/8"-

16 flange nut finger tight.

Hold the upper bracket tight against the bottom of the frame.

If the bracket appears to be level win the upper part of the

bracket rests against the inside of the frame, install the ¾"-16

x 3" bolt through the frame rail and upper bracket. If the top of

the bracket does not set level, install some of the large ¾" flat

washers between the bracket and the inside of the frame rail.

If you have existing hitch hardware, the ¾" bolt should be long

enough to extend through the upper bracket, truck frame and

hitch brackets. Be sure to install at least one of the large flat

washers and the ¾" lock washer before installing the ¾"-16 hex

nut onto the bolt. After you have installed the upper bracket as

level as possible, tighten the 3/8"-16 x 2 1/2" flat head bolt in the

bottom of the frame, then tighten the ¾"-16 x 3" bolt through the

side of the frame. The emergency brake cable will have to be

tie-wrapped out of the way using the hole provided in the upper

bracket. See Figure “A”.

STEP 3—AIR SPRING INSTALLATION

The heat shield will be used on the exhaust side of the truck

only. It is placed between the upper bracket and the top of the

air spring.

See Figure “B”. The alignment pin on top of the

air spring must be aligned with the hole in the upper bracket
