Step 1. Place the servo saver bottom (1) over the servo saver post (2)
and slide the servo saver bottom all the way against the hex at the
opposite end. Be sure that the hex on the servo saver post (2) is
inserted into the hex in the servo saver bottom (1).

Step 2. Slide the servo saver top (3) down over the servo saver post
(2) so that the 'V' area of the servo saver top (3) rests in the 'V' area of
the servo saver bottom (1). The arm on the servo saver top (3) and the
arm on the servo saver bottom (1) should point in opposite directions
as shown in Figure 1.

Step 3. Slide the servo saver spring (4) over the servo saver post (2)
and push it into the recessed area of the servo saver top (3). Install
the servo saver spring cap (5) and thread the 6-40 locknut (6) onto the
end of the servo saver post (2).

Step 4. Tighten the 6-40 locknut (6) all the way down and then loosen
it two full turns (e.g. 360

o

 x 2). This is a good starting point for the

adjustment. Once assembly is complete, if you wish, the servo saver
can be adjusted tighter or looser.

Step 5. Insert a 4-40 mini locknut (7) into the outer hex area in the
servo saver bottom (1) and steering idler arm (8) as shown in Figure 2.
Thread a 3/16" ball stud (11) through the outside hole in each arm,
into the nuts (7), and tighten. Insert a 4-40 mini locknut (7) into the hex
area in the servo saver top (3). Thread a 3/16" ball stud (11) through
the hole in the arm, into the nut (7), and tighten.

Step 6. Insert a 4-40 mini locknut (7) into the hex areas in the rear of the
servo saver bottom (1) and the steering idler arm (8) as shown in
Figure 2. Thread a 3/16" ball stud (11) through the arms, into each nut
(7), and tighten.

Tip: Once assembly of your new XXX-NT is complete, you may
notice that the tires toe in slightly as the suspension compresses. We
have found this setting to yield the best performance. Should you
prefer to change this so that the tires do not toe in, you can add one
ball stud washer under the ball studs on the outside of the servo
saver assembly and steering idler arm. To accomplish this, you will
want to replace the 3/16" ball studs with 1/4" ball studs.

Figure 3

Step 7. Snap one end of the steering drag link (12) to the rear ball

stud (11) on the servo saver bottom (3). Snap the other end to the rear
ball stud (11) on the steering idler arm (8).

*NOTE: Be sure to snap the rod onto the correct ball studs as

shown!
