Rough Country 1157 - Manual (Page 4)

These next steps will be necessary if the vehicle is equipped with a transfer case drop kit. If the vehicle does
NOT have a transfer case kit installed the bracket should NOT be installed. The bracket is designed to adjust
the 4WD shifter allowing the full range of the shift pattern. After drop bracket installation, check the
operation of the 4WD shift lever to ensure the transfer case engages fully in all ranges. Additional “fine
tuning” can be performed if the shifter does not fully engage in all the ranges. Refer to instructions on the
next page to adjust the shift linkage. It may also be necessary to trim the body under the middle console to
avoid interference with the shifter.
1. From underneath the vehicle, locate the shift control bracket. It is attached to the inside of the transmission tunnel
on the driver side and acts as a pivot for the transfer case shift lever.
2. Remove the shifter linkage from the shifter plate that is mounted on the body tunnel as shown using a 10 mm
wrench.
3. Reinstall the stock shifter bracket on the new drop
bracket as shown with the 1/4” x 3/4” hardware. Tighten
using a 7/16” wrench. See Photo 1.
4. Install the supplied drop bracket on the stock tunnel
bracket with the supplied 1/4” x 3/4” bolts/washers &
nuts. Tighten hardware using a 7/16” wrench. Check
clearance on bolts. See Photo 1.
Due to factory variations on the shifter rod bracket, it
may be necessary to modify the shifter bracket by
slightly bending the mount on the rod to clear the shifter
bracket or shifter bracket bolts. After noting how much
to bend the bracket to clear, remove the shifter
assembly and bend the bracket as shown to slightly
clear the bracket / bolts. Do not over-bend!! See Photo 2.
TRANSFER CASE SHIFTER BRACKET INSTALLATION INSTRUCTIONS
MAINTENANCE INFORMATION
It is the ultimately the buyers responsibility to have all bolts/nuts checked for tightness after the first 500 miles and
then every 1000 miles or 3 months. Wheel alignment steering system, suspension and driveline systems must be
inspected by a qualified professional mechanic at least every 3000 miles.
If the 4WD shifter engages in all ranges, the following
procedure will NOT be necessary.
1. Check the transfer case shifter to see if it will move to 4L. If
not, the linkage will need adjusting. Place the shifter in 4L,
loosen adjustment bolt and push the linkage forward until it
stops. Now re-tighten adjustment bolt. See Photo 1. Check to
be sure 4WD works properly.
