4. Starting with one of the front scissor jacks, remove the existing lower,
inside pivot bolt; replacing with a ⅜ ” x 4” swing-bolt. Install swing-bolt
from front-to-back with the shoulder of the swing-bolt to the front side
of jack. Place ⅜ ” washer and ⅜ ”-16 “Nylock” locking nut on threaded
end of swing-bolt. Tighten enough so that the swing-bolt will only
pivot by using a screwdriver for leverage. Ensure swing-bolt tab is
positioned horizontally.
5. Remove the existing lower, outside pivot bolt; replacing with 5”
swing-bolt. Install swing bolt from rear-to-front with shoulder of
swing-bolt to rear of the jack (Fig. 4).
6. Place a ⅜ ” washer and ⅜ ” locking nut on threaded end of swing-bolt
and tighten as explained in Step 4. Position swing-bolt tab vertically as
shown.
7. Repeat Steps 4-6 for opposite front jack.
8. Apply white grease to the threads of two “T”-bolts and partially
thread them into the top holes of the outer stabilizer tubes.
9. Remove inner stabilizer tube from assembly and discard the plastic
shipping bag. Reassemble stabilizer tubes with the inner tube sticking
out past the end of the outer tube by 1” (Fig. 5).

10. Tighten “T”-bolts until snug. To ensure proper installation, make
sure the warning labels are facing outward and right-side up.  e “T”-
bolts should also be on the top side of the stabilizers. Repeat Steps 9
and 10 for opposite side.
11. A er fully retracting front scissor jacks, attach the clevis end of the
stabilizer inner tube to the swing-bolt tab on the front side of the jack
using a ⅜ ”-16 x 1 ½” bolt with a ⅜ ” washer on the top and bottom of the
tab and a ⅜ ” locking nut. Tighten nut until tight. Repeat this step on
the opposite side.
12. Insert a ⅜ ” x 1 ¼ ” swing-bolt into a spacer mount and secure with
a ⅜ ” washer and ⅜ ” locking nut. Attach assembled spacer mount to
clevis end of the stabilizer outer tube using a ⅜ ”-16 x 1 ½” bolt and a ⅜ ”
washer on both sides of the clevis. Tighten a ⅜ ” locking nut enough to
allow the stabilizer to swivel by hand with some resistance. Repeat this
step for the opposite side (Fig. 6).
13. Swing stabilizer toward the center of the chassis and up to the
cross-member identi ed in Step 3. Ensure that the front of the spacer
mount is parallel to front of cross-member and the mounting holes are
centered front-to-back on the cross-member. With the spacer mount
held against the cross-member, mark the mounting hole locations with
a marker. Center punch each location. Drill a ⅛ ” pilot hole at each
mounting hole location. Drill out one of the mounting holes to ⁄” and
tap either using a ⅜ ”-16 tap or a ⅜ ”-16 x 1” self-tapping bolt. Lubricate
as needed. Remove tap or bolt and secure spacer mount with a ⅜ ”-16 x
1” self-tapping bolt, taking care to keep the remaining pilot hole cen-
tered in the mounting hole of the spacer mount. Tighten bolt securely.
Drill remaining pilot hole to ⁄” and insert a ⅜ ”-16 x 1” self-tapping
bolt and tighten. Repeat this step for opposite side (Fig. 7).
NOTE: For chassis that are constructed with “I” or “H” beam main rails
(front-to-back) and are uninsulated, refer to Step 14. For chassis that are
constructed with “I” or “H” beam main rails or tubular frames and/or
insulated, refer to Step 15.
14. Measure from the rear side of the front scissor jack 30” and place a
mark on the bottom of the main rails. Measure the bottom  ange of the
main rails and divide by 4 for center of mounting hole. Center punch at
the intersection of the lines and drill an ⅛ ” pilot hole. Drill out the pilot
hole to ⅜ ” and deburr. Secure a sti ening pad to bottom of the main
rail  ange using a ⅜ ” x 1 ¼” swing-bolt, a ⅜ ” washer, and a ⅜ ” locking
nut.  e edge of the sti ening pad should be parallel to the edge of the
main rail  ange. Drill remaining mounting hole and secure with a
⅜ ”-16 x 1 ½” bolt, ⅜ ” washer, and ⅜ ” locking nut (Fig. 8). Repeat this step
for opposite side.
