Skyjacker DS393 - Manual

1. Secure and properly block the tires of vehicle on a level con-
crete or asphalt surface. Open hood, remove the upper
shock nuts and retainers, remove the 3 nuts on the upper
shock tower brackets and remove brackets.
2. Jack up front of vehicle and install jack stands under frame
behind the lower link rear brackets. Remove tires. Lower
front axle down until coil springs become loose. Remove
coils, rubber insulator and 3-bolt tower ring.
3. Start new 3-bolt tower ring (with square holes using 7/16" car-
riage head bolts supplied) up into position. Start bolts one at
a time (you must be sure the bolt heads are aligned in the
square holes) using 7/16 "standard" nuts to hold in place (do
not use self locking nuts, they will be used later). Note:
There will be a 4th mounting hole (located betwwen the shock mounts) that must be drilled. With
tower ring installed, mark and drill the additional hole using a 7/16” drill bit. Install suppled 7/16 x 1
1/2” carriage bolt, washers, and nut. Tighten nuts and repeat on other side. (See Photo #1)
4. Start coil springs at bottom first, place rubber isolator on top of coil and then start coil into position in the
upper tower, on both sides. Align coil springs so that the bottom
end of the coils are turned to the inside - center of the axle. Lift up
on jack under differential until coil springs are securely in place,
and keep a load on them to hold in place.
5. Install new OEM position shock located inside coil spring. Install
shock down through center of coil spring tower and tighten lower
shock bolt. Now remove 7/16" standard nuts that were installed on
3-bolt tower ring in step 3. Install new upper dual shock bracket
over 3 bolts of tower ring, then the original upper shock bracket
(See Photo #2) There is a left and a right bracket - the attached
shock mounts should curve rearward on each side. Install the 7/16"
self locking nuts and tighten. Install shock grommets, retainer
washers, nuts and tighten.
