INSTRUCTIONS:

1. Disconnect the negative terminal on the battery. Jack up

the rear end of the truck and support the frame rails with

jack stands. NEVER WORK UNDER AN

UNSUPPORTED VEHICLE! Remove the rear tires.

2. Disconnect the sway bar end links from the frame and sway

bar, discard the endlinks, save the hardware. Remove the

bolt securing the brake line support tab to the differential

housing and save. Remove the ABS wiring from the frame

mounts on both sides. Save all the hardware. SEE PHOTO

BELOW.

3. Using a floor jack, raise the differential just enough to

slightly compress the rear shocks. Remove the bolts

securing the top of the shocks to the frame (if equipped

with the Auto Ride System, unplug the electric and air line

connections) . Remove the lower pivot bolt that attaches

the track bar to the axle bracket and save. SEE PHOTO

BELOW.

4. Lower the floor jack to release the coil springs. Remove

the coil springs from the vehicle and save the rubber upper

and lower coil insulators.

5. Support the rear axle with a floor jack and remove the

factory lower links arms. Discard the links and save the

hardware. SEE PHOTO BELOW.

6. Locate FT20319 (drv) & FT20320 (pass) Rear Bumpstop

Brackets and the supplied 3/8”x1 ¼” hardware. Place the

bump stop extension mounts onto the existing pads on the

top of the differential. Using the 3/8” bolts, washers and

C-lock nuts, secure the mount to the differential. There

should be a flat washer on each side of the bolt. Do not

fully tighten. Mark and drill the front 3/8” hole in the

bumpstop and attach using the remaining 3/8” hardware on

this new hole. Torque to 30 ft lbs. SEE PHOTO BELOW

AND ON THE NEXT PAGE.

7. Locate FT20360 (drv.) & FT20361 (pass) Rear Upper Link,

FT20362 Rear Lower Links, and FT20299 Bushing and

Sleeve Kit. Using an arbor press, press the bushings and

sleeves (use supplied bushing lube) into each end of the

links and install the supplied zerk fittings. On the upper

links, use 2ea. FT1037 bushings and a short sleeve at each

end. On the lower links, use 1ea. FT1037, 1ea. FT1006 and

a long sleeve.

8. Install the new Lower Link Arms into the factory rear axle

mounts with the factory hardware. Then attach the arm to

the frame mounts also with the factory hardware. Leave

loose at this time. SEE PHOTO BELOW.

9. Support the rear axle with a floor jack and remove the

factory upper links arms. If the rear is equipped with

Auto Ride, locate the Auto Ride sensors on both the

driver side and passenger side of the vehicle on the

upper link arms. Disconnect from the link arm and save

with the hardware. DO NOT REMOVE FROM THE

TRUCK. Discard the links and save the hardware. Install

the new Upper Link Arms into the factory rear axle mounts

with the factory hardware. (install / match the driver and

passenger links as they were removed). Then attach the

arm to the frame mounts also with the factory hardware.

Remove the Auto Ride bracket from the position sensor and

use a die grinder to remove the bottom of the bracket.

Connect the auto ride brackets to the tabs on the upper links

with the factory hardware. Leave the link arm bolts loose at

this time. SEE PHOTOS BELOW

Photo shows cutting of factory bracket

10. Locate FT20292 Trac Bar Bracket, FT20307 Trac Bar

Bracket Support, and the 7/16” & 9/16“ hardware. Position

the trac bar bracket into the factory mount on the axle and

install with the factory bolt and hardware. Leave loose.

Locate the two factory holes just forward of this mount,

Using a drill with a 7/16” bit, drill these two holes out to

7/16” (carefully bend the brake line back from the inner

hole). Position the support bracket over the two new holes

and install with the 7/16” x 2 ¼” bolts and hardware. Insert

the 9/16” x 4” bolt into the trac bar bracket and support

bracket (tighten just enough to make the bracket and

support make contact, over tightening without the trac bar

installed will collapse the bracket) Torque the 7/16” bolts to

50 lbs. SEE PHOTOS BELOW AND IN NEXT

COLUMN

11. Using a drill with a 7/16” bit, drill the hole on the new trac

bar bracket to the factory mount. Use 7/16 x 1 ½” bolt and

hardware to attach the bracket to the mount and torque to

50 lbs. SEE PHOTOS BELOW

Provided

9/16” x 4” Bolt

Factory Bolt

12. Working from the driver’s side, locate FT1599-2-2D Shock

Drop Bracket. Slide the shock mount extension into the

original frame mount and insert one of the factory shock

bolts and hardware through the original shock mount side

and hand tighten. Take one of the new sway bar links and

insert 2 bushing halves and a sleeve into each end (use the

supplied lube). Install one end of the end link into the frame

mount and insert the original bolt through the sleeve, (the

factory hole may have to be drilled out with a ½” drill

bit to align properly) securing the shock mount drop

bracket. Torque the factory bolt to 75lbs and the upper bolt

shock bolt to 85lbs. SEE PHOTOS ON NEXT PAGE.

IF YOU ARE INSTALLING DIRT LOGIC REAR SHOCKS,

BRACKETS. THE DIRT LOGIC SHOCKS WILL MOUNT

DIRECTLY INTO THE FACTORY UPPER AND LOWER

SHOCK MOUNTS

13. Repeat step twelve on the passenger side of the truck.

14. Place a floor jack under the rear axle. Attach your coil

spring compressor onto the new rear coil spring and

compress the coil 1”-2”. Set the upper coil insulator on top

of the coil spring and position the top of the coil into the

frame pocket. Push the bottom of the coil spring onto the

axle pad and raise the floor jack under the axle to hold the

coil spring in position. Remove the coil spring

compressors. Repeat this with the opposite coil spring.

16. Working from the driver’s side, electrical plug. Follow the

electrical plug to the plastic loom, carefully open the loom

and ONLY remove the ABS wires from it back

approximately 10 inches. Route the plug and line down to

the shock and plug in. SEE PHOTO BELOW

17. Remove the air line manifold from its connection point in

the rear wheel well. Bring the manifold forward just behind

the rear shock. The supply line needs to be swapped on the

manifold with the line to the driver side shock. Remove the

clips from the ends and swap the two lines. Use a drill with

a 15/64” drill bit and drill a hole into the plastic liner and

insert the manifold into it. Use two of the supplied 8” zip

ties and attach the ABS & Electrical lines to the shock

extension. Use two of the supplied 14” zip ties and attach

the ABS line to the shock ABOVE THE SHOCK

BLADDER. SEE PHOTOS
