BMR Suspension TA010 User Manual

TORQUE ARM INSTALLATION INSTRUCTIONS

TA010 - 1968-1974 Nova 10 BOLT

Please take note before proceeding with this installation:

• This product may interfere with certain exhaust kits. Exhaust crossovers are not

compatible with this torque arm suspension. In some circumstances, it may be necessary
to fabricate a custom exhaust for proper clearance.

• While not necessary, a heavy duty cast aluminum differential cover is recommended with

this kit. These covers are more structural in nature than the stamped steel OE unit and
will distribute the load across the differential, further strengthening the assembly.

TOOLS REQUIRED:
3/8” and ½” drive ratchets

½”, 5/8” deep, 9/16”, ¾” deep, 15/16” and 1-1/8” sockets
Pry-bar
3/8” Allen wrench

ADDITIONAL ITEMS REQUIRED:

RTV gasket silicone
Gear oil

CROSS-MEMBER
INSTALLATION:

1) Lift the vehicle and support

with stands under the rocker
panel pinch seams (Do not
place stands under the
subframe).

2) Remove the exhaust system.

3) Using a 15/16” socket,

remove the rear two body
mount bolts.

4) Remove the OE rubber body

mount bushings. They are
composed of an upper and
lower bushing that
“sandwich” the subframe
together in the middle. NOTE: a pry-bar may be necessary to get the subframe low
enough to remove these bushings.

5) Once the OE bushings have been removed, inspect the subframe for rust damage. This is

a common area susceptible to rust and if the mounting point is compromised, it needs to
be repaired before proceeding with the installation.

6) Begin with the driver’s side. Assemble the driver’s side frame mount, billet body mounts

and washer (if necessary) as shown in the image above. If you are using a subframe
connector that mounts around the body bushing, omit the supplied aluminum spacer
washer shown in Image 1 above.

CROSS-MEMBER INSTALLATION (Cont.)

7) Thread the supplied 5/8” bolt, washer and lock washer into the body and snug the bolt

just enough to allow the frame bracket to rotate around the axis of the bushing.

8) Repeat steps 4-7 for the passenger side. At this stage both mounts should be installed and

you can mount the cross-member. Lift the cross-member into place and insert the
supplied ½” x 4.5” bolts, (8) stainless washers, and nuts.

9) Tighten the body mount bolts to 150 ft/lbs.

10) Center the cross-member to the driveshaft then tighten the (4) cross-member bolts.

TORQUE ARM INSTALLATION INSTRUCTIONS:

1) Remove the differential drain plug or loosen the cover bolts to drain the gear oil from the

differential.

2) If it was not necessary to remove the cover previously, remove the 12 bolts from the

differential cover and remove the cover.

3) Using a gasket scraper, remove all

gasket material from the cover and the
differential.

4) Thread the four supplied 5/16” studs into

the differential at the four corners. All
studs should bottom out and should
thread in to the same depth. If not, run a
5/16-18 bottoming tap through the holes
in the differential.

5) Apply a thin bead of RTV Black or Grey

gasket silicone onto the differential
gasket mating surface. Install one of the
supplied gaskets.

6) Apply another thin bead of RTV on the exposed gasket surface. Position the BMR torque

arm mounting plate onto the rear end with the torque arm mounting points facing forward
as in Image 1 above.
