NOTES: Be sure to read and fully understand these instructions before starting the installation process. These hoops are
designed to run a shock with about 12-14" of travel on a vehicle with approximately 3-7" of lift. Proper shock length is determined
by spring travel, vehicle use, and the placement of the bumpstops relative to ride height. This shock hoop can be installed with
any ride height, but shock length must be varied for proper fitment. It is the responsibility of the installer to cycle the
suspension and determine the proper shock absorber length prior to installation.
1) Raise and support the rear of the vehicle so that the rear suspension is easily accessible.
Remove the spare tire from under the rear of the vehicle if applicable.
2) Remove the bolts that mount the rear brake proportioning valve to the frame rail. Remove the
valve or CAREFULLY bend the lines to pull the valve assembly away from the frame. Fully clean the paint from the inside face
of the frame directly above the bumpstop drop bracket on both sides.
3) Before placing the shock hoop in the vehicle we recommend painting all but the outer edges where
the welding will take place.
4) Place the shock hoop between the frame rails directly above the bump-stop drop bracket with
the 3" square gussets between the hoop sides and frame. This may be a "press fit" and may even require a small amount of
grinding to the ends of the hoop to allow proper fitment. The hoop should be placed so that the shocks will be mounted toward
the rear of the vehicle. When looking at the setup from the side of the vehicle with the rear suspension unloaded, the shocks
should be angled with the bottom slightly toward the front of the vehicle, so that at ride height the shocks will be standing
straight up and down.
6) Once properly aligned, tack-weld the hoop and gussets into place. Double-check the alignment
of the hoop before fully welding. Carefully weld the hoop and gussets into place. We recommend welding the gussets to the
frame on all 4 sides in "stiched" sections, leaving consistent small gaps to allow flex in the components. We then recommend
fully welding the hoop to the gussets.
7) Remove the parking brake cable from the actuator levers on each brake drum backing plate.
Remove the 2 bolts that retain the proportioning valve lever to the axle housing.
8) Clean a 3"X3" section of paint from center of the rear face of the axle housing. This should
be done so the center of this section is approx. 2.5" to the inside of the inner leaf spring U-bolt.
9) Using a level or whatever tools necessary center and align the mounts on the axle housing, then
tack weld into place. Double check the mount position. Fully weld mounts to the axle housing.
10) Once everything has cooled, paint the bare metal on the frame, hoop, and axle housing.
11) Once the paint has dried, install and fasten the proportioning valve to the frame rail. The
brake lines will have to be re-bent to clear the shock hoop. Be careful not to "kink" these metal lines.
12) Install the proportioning valve lever bracket on the axle housing. In some cases the proportioning
valve lever may interfere with the shock body. If this is the case, we recommend relocating the proportioning valve axle bracket
to the front of the axle housing, next to the differential. In doing this, be sure that the lever mount is placed at the same
height it was at on the rear side of the axle housing. If using the same axle mount with a lift, we recommend raising the lever
by way of bracket, if necessary, ORS can provide this bracket.
13) Install the shock absorbers on the shock hoop with the provided bolts, nuts, and washers. Place
one washer on each side of the shock eye. Fasten the parking brake cables to the levers.
14) Re-install the spare tire and lower the vehicle to the ground. Cycle the suspension and check
for proper shock clearance, length, and fitment. CAUTION: At times the rear brake proportioning valve actuating lever may have
to be modified to clear the shock absorber body.
15) With certain shock setups, we recommend using a set of larger bump-stops in place of the stock
units. If interested, ORS can provided a set of bumpstops.
