TRANSFER CASE INSTALLATION INSTRUCTIONS ( IF PURCHASED)
If you are not installing a slip yoke eliminator, and driveshaft follow the following instruction to install the trans-
fer case drop brackets. NOTE- The slip yoke and drive shaft is highly recommended for the 6” kit. Vibration will
be present if only the transfer case lowering kit is used
1. Place floor jack under transmission mount skid plate. Make sure the jack is centered.
2. Using a floor jack, support the skid plate.
3. Slightly loosen the bolts on the transfer case skid plate on both sides to allow for some movement. Do not remove
the bolts. See Photo 1.
4. Proceed to either side. NOTE: Do not attempt to take out the bolts on both sides simultaneously. Installation
is done one side at a time. Remove the three bolts holding the transfer case skid plate to the frame rail. Note: It
may be necessary to loosen the bolts holding the transfer case to the skid plate to allow for movement to install the
lowering spacers on the skid plate.
5. Locate transfer case cap plug bag and install in the transfer case spacer. Slightly lower the skid plate and insert the
transfer case lowering spacer. See Photo 2. The spacer has a front and back (the holes line up in only one direc-
tion). When the transfer case is dropped it will tend to move forward, to get the new bolts to align with holes in frame
rail you will probably have to push the transfer case skid plate towards the back of the vehicle or loosen the trans-
mission mount bolts on the bottom of the skid plate.
6. Using the conical bolts supplied slightly tighten the bolts. Do not fully tighten to allow for some movement for the
opposite side.
7. Proceed to the opposite side of the vehicle and install the brackets as instructed above. After installing both sides,
tighten bolts– do not over tighten.
8. It may be necessary to remove some material from the body underneath the shifter on the manual shift models to
allow clearance for shifting into all gears. To accomplish this, remove the shifter boot from the shifter. Go through
the shift pattern and note where the shifter is coming in contact with the body. Remove approximately ¼”- of material
from the body with a small grinder. Generally the gears affected are 2nd, 4th and reverse. Go through the shift pat-
tern again and note any contact. Trim accordingly. Reinstall the boot and secure.
