Rough Country 875.20 - Manual (Page 12)

REAR INSTALLATION INSTRUCTIONS
If the vehicle is equipped with an electric locker, it will be necessary to free the line from the differential and
reroute to allow slack in the line. The lines can be secure with a zip tie to keep them out of harms way.
1. The next 2 steps will be performed with the vehicle on the ground. This is done to ensure adequate brake line length
when installing the rear blocks.
2. Remove brake lines from the brake line bracket on the axle using 12mm wrench and install new bracket in the stock
location using supplied 8mm x 25mm bolts /washers with 12mm wrench to secure the bracket to the axle. Relocate
the stock brake lines to the top of the new bracket and secure with the supplied 5/16” x 1 1/4” bolts, washers & nuts.
See Photo 1. Tighten with 13mm wrench.
3. Remove the 2 emergency brake cables from the frame using a 12mm wrench and install the new bracket to the
stock location using factory hardware. Relocate the e-brake cables to the bottom part of the bracket as shown in
Photo 2 and secure using the supplied 5/16” x 3/4” bolts, washers /nuts. Secure with a 13mm wrench.
4. Chock the front tires and lift the rear of the vehicle,
position jack stands under the rear frame rails of the
vehicle and lower the vehicle on to the jack stands.
5. Place a floor jack in position under the rear differential for
support.
6. Remove shocks using 19mm wrench for upper and lower
bolts. Retain stock hardware.
7. With slight pressure on the rear axle, remove U-bolts
using a 22mm socket.
8. Lower the axle down to allow clearance to install the
supplied blocks. Align the blocks on the factory center pins
on the leaf spring and align the pin on the block with the
axle. NOTE: The hole and the pin in the new blocks are
slightly offset. The offset will go toward the front of
the truck moving the axle slightly forward.
9. Install the supplied shock absorbers with the stock hardware using a 19mm wrench.
10. Install supplied u-bolts and tighten with 13/16 socket. See Photo 3.
11. Install the wheels/tires. Jack up the vehicle and remove the jack stands and lower the vehicle to the floor.

POST INSTALLATION INSTRUCTIONS
1. Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed,
and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring
harness. Check steering gear for clearance. Test and inspect brake system.
2. Perform steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile or
heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/
replacement may result in component failure.
3. On some vehicles the front lower skirting will need to be trimmed if using certain wheel /tire combinations and with
heavy offset wheels. Trim only as needed.
4. Have a qualified alignment center align the vehicle immediately. Realign to factory specifications. Perform head
light check and adjustment to proper settings.
5. Check and retighten wheels at 50 miles and again at 500 miles.
6. All kit components must be retightened at 500 miles and then every three thousand miles after installation.
Periodically check all hardware for tightness.
7. Install “Warning to Driver” decal on sun visor
8. Note: Installation of larger tires will require speedometer recalibration.
