• Now align the g-load brace/cross member mounting holes with the four
mounting holes in the frame of the car and install the four supplied bolts into
the frame. Make the bolts hand tight only
• Line the front torque arm mount (bushing or rod end) hole up with the top
hole of the two rotator plates on the crossmember front mount and install the
supplied 5/8” bolt and lock nut hand tight.
at this time. Do not re-use the
original g-load brace bolts! Your package was shipped to you with four new
bolts, these bolts are longer than the original bolts. The longer bolts are
needed due to the thicker mounting brackets our heavy-duty g-load brace
uses. Be sure to install the supplied flat washers between the bolts and the
brace. NOTE: If you are using subframe connectors that tie into the g-load
brace mounts you will need bolts longer then the bolts we supplied. For this
application you will need to obtain (4) bolts that are 8mm x 1.25 pitch (metric
course) x 35mm length. The bolts we supply are 25mm length, you will need
to have 35mm length for proper thread engagement with the added thickness
of the subframe connector mounts.
• Tighten the two bolts that secure the torque arm to the rear housing.
• Tighten the four bolts that secure the g-load brace/cross member to the
frame of the car.
• IMPORTANT: All of the bolts and jam nuts on the Spohn torque arm are
shipped hand tight to allow for play when installing, they must all be
tightened at this time! TIP: To keep jam nuts from loosening over time from
road vibrations, apply a drop of removable strength
• Tighten the two bolts that secure the two rear solid rod ends to the rear
housing mounting bracket.
(Blue) Loctite onto the
threads, and then tighten the jam nuts.
• Tighten the top front rotator mount bolt to 100 ft/lbs.
• IMPORTANT: The bottom connection of the front rotator mount should be tightened
to 50 ft/lbs. If going by feel, bring the nut in until you feel it start to snug tight against
and then stop.
• Read the attached pinion angle adjustment instructions. After setting your
pinion angle, tighten the three jam nuts at the rear of the torque arm. The
two jam nuts towards the rear of the arm that secure the solid rod ends are
right hand threaded and tighten clockwise as normal. The jam nut in front of
the pinion angle adjuster that tightens against the lower torque arm tube is
left hand threaded, and thus tightens by turning it counter-clockwise.
Note: Before adjusting your pinion angle, you must first loosen the two bolts
that secure the two rear solid rod ends to the rear-housing mount. This allows
the torque arm the ability to swivel up or down as you adjust the pinion
angle. If you do not loosen these two bolts the assembly will bind and you will
not be able to adjust the pinion angle. After setting the desired pinion angle,
retighten these two bolts.
