BEFORE YOU GET STARTED

Before you begin the installation of your new adjustable
torque arm, it is very important that you inspect several
components on your vehicle for safety reasons, to
eliminate potential problems and to ensure your new
torque arm will work properly for a long time to come:

1. Inspect the motor mounts and the transmission
mount. Worn, weak or broken mounts will cause
the torque arm to not function properly and can
cause damage to your vehicle. Stock OE
transmission mounts in Camaros and Firebirds are
very weak and known to fail. If you have a broken
or weak transmission mount, it will cause the
torque arm to actually lift the tail end of the trans.
up. This could cause severe wheel hop, driveline
misalignment and possible damage to the
transmission, drive shaft, u-joints, rear axle,
torque arm, and/or floor pan of vehicle. We highly
recommend using a good quality polyurethane
transmission mount like Energy Suspension #33-

1108. Using the Energy Suspension transmission
mount is good insurance that your transmission
stay solid and the torque arm will work to its full
potential.

has a job and relies on the other components to do
their jobs. The installation of a high performance
torque arm alone will not mask worn or inferior
components. Use of an adjustable panhard rod
like Edelbrock (#5222) will allow you to re-center
your rear axle if your cars ride height has been
altered. We would like to stress the importance of
having a good solid chassis and suspension
system. Using Edelbrock products can help make
your car much safer as well as more fun to drive.

NOTE: Do not make any adjustments to your new
torque arm prior to installation. Your new torque arm
comes adjusted to stock configuration. Pinion angle
adjustments are very tricky and should only be done by
someone with a good understanding and the knowledge
of how to make proper adjustments. If adjustments are
made to pinion angle, it is very important that the rod
ends sit straight up and down and not angled between
the differential bracket, and that you have a minimum of
1" of thread engagement in the adjuster sleeve and rod
ends or it could cause the part to fail. Improper
adjustment, defective, worn, or inadequate suspension
components as mentioned above could cause torque
arm to fail causing damage or injury. Edelbrock Corp. is
not responsible for any damage or injury.

2. Inspect the rear suspension bushings. We strongly
recommend using either Edelbrock (#5274) lower
trailing arms with a spherical ball on one end and
polyurethane bushings on the other, Edelbrock
(#5204) trailing arms with polyurethane bushings
on both ends, or other high quality trailing arms
that use high quality polyurethane bushings. We
also recommend the use of an Edelbrock or other
high quality panhard rod to replace the stock OE
piece that uses sponge rubber bushings. The
lower trailing arms and panhard rod secure the
rear axle under the car. Upgrading to stronger
high quality tubular trailing arms and panhard rod
with polyurethane bushings will increase the
overall strength, eliminate the sponge feel of
rubber bushings and further increase the function
potential of the torque arm. Worn out trailing arm
or panhard rod bushings can contribute to or
cause torque arm or other suspension component
failures. Remember each suspension component

A drive on vehicle lift is recommended for proper and
easy installation.

Before you start, check and record current pinion angle.
(NOTE: Vehicle should be on level surface and in correct
ride position to obtain correct information.)

INSTALLATION INSTRUCTIONS

1. If you are not using a drive on lift, raise vehicle and
support under the frame so the rear end can be
raised and lowered, if needed.

2. Remove the two large bolts that attach the stock
arm to the differential and remove stock torque
arm. Inspect bolts and replace, if necessary. (Use
only OE bolts and OE style lock nuts)

3. Unbolt and remove the front bushing bracket
assembly from the transmission.
