6.  Repeat steps two through five on passenger side of truck.

7.  Locate FT20275BK Coil Spacers and the supplied 10mm 

nuts and flat washers. Attach the Coil Spacer to the top of 
the factory coilover and torque to 30 ft-lbs. 

(DO NOT USE 

AN IMPACT ON THE FACTORY STUDS)

 Using a die 

grinder with a cutoff wheel, cut the excess of the factory 
studs flush with the top of the coil spacer. If required, 
use a die grinder with a sanding disc and sand the stud 
flush with spacer. Be sure not to cut into the spacer. 

SEE 

FIGURES 6-7

8.  Install coilover and rotate it 180 degrees from the original 

position. This will align the new spacer to the original 
mounting holes in coilover mount. Attach the bottom 
part of the coilover to the lower A-Arm with the factory 
hardware. Torque bolts to 30 ft-lbs.

9.  Using the supplied 3/8”x 1-¼” bolts, flat washers, split 

washers and thread locking compound, attach the 
coilover into the factory coilover mount. Torque to 30 ft-
lbs.

10.  Attach the upper ball joint to the factory knuckle using the 

factory nut. Torque to 60 ft-lbs. Now reattach the tie rod 
to the steering knuckle using the factory nut. Torque to 50 
ft.-lbs.

11.  Attach the factory swaybar endlinks with the factory 

hardware and tighten just till the bushings start to bulge. 
Attach the autoride bracket to upper A-Arm using the 
factory hardware. Re-connect the ABS sensor plug and 
attach the ABS line back to the upper A-Arm mount.

12.  Install tires and wheels and torque lug nuts to wheel 

manufacturer’s specifications. Turn front tires left to right 
and check for appropriate tire clearance. 

Note - Some 

oversized tires may require trimming of the front 
bumper & valance.

13.  Check front end alignment and set to factory 

specifications. Readjust headlights.

14.  Recheck all bolts for proper torque. 

15.  Recheck brake hoses, ABS wires and suspension parts 

for proper tire clearance while turning tires fully left to 
right.

16.  Check the fluid in the front and rear differential and fill 

if needed with factory specification differential oil. 

Note 

- some differentials may expel fluid after filling and 
driving. This can be normal in resetting the fluid level 
with the new position of the differential/s.

17.  Install Driver Warning Decal. Complete product 

registration card and mail to Fabtech in order to receive 
future safety and technical bulletins on this suspension.

Vehicles that will receive oversized tires should check ball 

joints, uniballs and all steering components every  

2500-5000 miles for wear and replace as required.

RE-TORQUE ALL NUTS, BOLTS AND LUGS 

AFTER 50 MILES AND PERIODICALLY
