The vehicle should be on a level surface before you start.
1. In a couple short hours you can update your Impala with new Speedtech
Performance trailing arms. We recommend you inspect all of your car's
suspension components prior to installation of our parts, such as bushings and
brake lines which may be worn and could cause adverse effects.
2. Jack up and properly support the vehicle on sturdy jack stands, two supporting
the rear axle and two supporting the front of the frame. Remove the rear wheels.
With the rear axle supported, record pinion angle AT RIDE HEIGHT. You will
need to match this number after your new trailing arms are installed. An easy
way to do this is attach your pinion gauge to the heads of two rear end cover
bolts that align vertically.
3. Support the rear of the frame with jack stands. Remove the shocks and
watching that you don't stretch the brake hose, carefully lower the rear axle until
you can remove the coil springs. Support the axle with jack stands. Place
another jack stand under the pinion ujoint to keep the rear axle from rotating
once it is unbolted. Remove the upper trailing arms.
4. Using the factory upper arms, line up the bolt holes with those on the
Speedtech upper arms. If an adjustment is needed, the Speedtech Articulink
control arms are threaded and can be adjusted by twisting them either to the
right to shorten or left to lengthen. See diagram on page 4.

5. You will need to drill out the trailing arm bracket holes to 9/16” here at the body
for the upper arm. Do Not drill out upper axle mounts. Using the 9/16” bolts install
the Speedtech upper trailing arms with the grease fitting pointing downward.

5. Remove the factory lower trailing arms. Drill out the lower trailing arm mount
bolt hole on the frame and the lower mount bolt hole on the rear axle to 9/16”.
Adjust the Speedtech lowers as needed in the same manner as the uppers.
Install the trailing arms with the new bolts. Raise the axle to ride height and
recheck pinion angle. If the angle is off, remove the rearward end of the lower
trailing arms. Adjust the driver's side arm and reinstall. Adjust passenger arm to
match bolt hole alignment and reinstall. Check pinion angle again. Repeat
process until desired pinion angle is achieved.
6. Check to make sure the rear axle is laterally centered side to side in the car
and the wheels are centered front to back in the wheel opening. Adjust trailing
arms as needed. Always be sure pinion angle is rechecked as centering
adjustments are made.
7. Reinstall coil springs and shocks.

Sway Bar Installation
1. Use the sway bar hardware to attach bar to the rear axle. Do not fully tighten
at this time. See sway bar instructions for further information.
2. You will not be using the end links and associated hardware that come with
the sway bar. Bolt the end links that come with the trailing arms to the sway bar
on the inside of the bar, with the spacer between the link and the sway bar. Do
not fully tighten yet. Attach the upper link brackets to the links and position with
the vertical tab against the front of the frame cross member. Be sure the links are
standing vertically. Mark three holes to bolt down each of the brackets. Remove
the bracket from the links and drill the holes with the 5/16”” bit. Bolt down the
brackets with the 5/16” bolts, nuts and washers, then bolt the links to the
brackets using the 3/8” bolts.

7. Double check to be sure all bolts are tight.
