Step 1: If your vehicle already has a shifter of any type installed, disconnect all shifter linkage
and remove the shifter and its related hardware (neutral safety switch, back-up light
switch, etc.).
Step 2: Determine exactly where you want the shifter to be located. The shifter may be mounted
either on top of the floor or underneath the floor, but under the floor is preferred in most
applications.
NOTE: For vehicles that had a floor shifter previously, determine if the existing hole in
the floor will be adequate for mounting and operation of the Lokar shifter. If not, the
floor will need to be modified.
If you are mounting the shifter on top of the floor, you will need a slot in the floor for
the quad arm to pass through. If you are mounting the shifter underneath the floor, the
opening will need to be large enough for the floor mount mounting bracket also.
Step 3: There are two pairs of floor mount tabs in the shifter kit. Which pair goes where will depend
on if you are mounting the shifter above or below the floor. See
Fig. 2 to determine how the
floor mount tabs need to be positioned for your particular application.
The floor mount tabs on the rear of the shifter must be installed with the ears pointing
towards the rear of the vehicle. If you are using the Lokar rectangular shifter boot and
ring mounted directly to the floor, the floor mount tabs on the front of the shifter must
also be installed pointing towards the rear of the vehicle. If you are not using the Lokar
rectangular Shifter Boot and Ring, you may install the front floor mount tabs facing
either direction.
Attach the floor mount tabs to the floor mount mounting bracket as shown in
Fig. 2 with
the 5/16"-24 x 1/2" button head bolts and lock washers. Leave the bolts loose enough
so that adjustments can be made later during the installation.
Step 4: Make sure the two 5/16"-24 x 3/8" socket head bolts that are in the curved, slotted
holes in the left side of the floor mount mounting bracket are tight. Place the shifter in
the desired location on the vehicle's floor. Make sure the shifter will not interfere with
the dash when in Park, or with the seat when in low gear. The shifter assembly may be
tilted forward or backward if needed by loosening the two socket head bolts that are in
the curved, slotted holes in the left side of the floor mount mounting bracket. Retighten
the socket head bolts in the curved, slotted holes once you have the shifter assembly at
the angle you want.

If you ever disassemble the shifter assembly, be sure that the 5/16"-24 x 3/8” button
head bolts and lock washers are put back into the curved, slotted holes in the floor
mount mounting bracket. Installing longer bolts will prevent the shifter from operating.
NOTE: If you find after installation that the shape or length of the shifter lever is not
suitable for your application, Lokar has a number of different styles and lengths of
shifter lever replacement kits available for purchase separately through our dealer network.
Step 5: Push the floor mount tabs flush against the floor, and mark the center of the bolt holes
in the floor mount tabs onto the floor. Center punch the marks, and drill four 5/16"
diameter holes.
Step 6: Attach the shifter to the floor using four 5/16"-24 x 1/2" button head bolts and nylock
jam nuts. Once the shifter is mounted to the floor, tighten the floor mount tab to floor
mount mounting bracket bolts.
Step 7: Make sure the shifter is in the Park position. Determine which one of the quad arms
included in the kit should be used to mount to the quad lever. There are three different
options to choose from: straight, 1-1/4" offset and 2-1/2" offset. Choose the quad arm
that will line up the best with the trans gear lever on the transmission. It is not necessary
that the quad arm be perfectly aligned with the trans gear lever. The rod ends allow for
a certain amount of misalignment.
Position the quad arm in place on the quad lever with the bolt holes aligned. Check
for interference with the left rear floor mount tab or the vehicle floor. With the shifter
in Park, you want the quad arm to be as close to the 4:30 – 5:00 position as the floor
mount tab will allow, without the quad arm touching the floor mount tab or floor.
If the quad arm is not in the proper position, loosen the set screw in the top of the quad
lever with a 1/8" Allen wrench and slide the quad lever off of the shaft. The shifter may
have to be removed to do this, depending on how large the opening is in the tunnel.
Reposition the quad lever on the shaft as close to 4:30 – 5:00 as the floor mount tab
allows, and retighten the set screw.

and nylock jam nuts.
