Installation Instructions

1. Raise and support the vehicle with jack stands on a stable surface. Note:

Never rely on a jack alone to support a vehicle.

CAUTION: Sway bars are heavy steel parts that can cause injury if
unsupported during removal or installation.

Note: Vehicles not originally equipped with a rear sway bar will require

boxed trailing arms such as QA1 #5208 for best performance. OEM
boxed arms for ‘73-’77 A-bodies can be used on those model years,
but will require 7/16”-14 x 2 ½” long bolts be purchased separately.

2. Use a small pry bar to spread the sway bar mounting blocks; install the

mounting blocks onto the QA1 sway bar (two per side). See Figure 1.

3. Use the supplied hardware to install in the following order:
a. Place one thick washer onto the bolt, and then slide the bolt up

through the mounting block. (Figure 2)

b. Install the QA1 sway bar and bolts through the trailing arms,

Figure 2

followed by the thick washers, then the locking nuts.

4. Adjust the sway bar so that it contacts both trailing arms evenly and

squarely in the vehicle. The best way to ensure that the sway bar is
mounted squarely is by measuring from the first bend in the sway bar to
the rear surface of the mounting block, verifying that the measurements
are the same for both sides. Torque the mounting hardware to 50 lb. ft.
at this time.

5. Check for any contact with brake lines, electrical wiring, fuel lines or

cables. Adjust the sway bar as needed.

Note: It is best to use sway bars that have been designed to work together.

Never drive a vehicle with only a rear sway bar installed, as this can
cause a dangerous over steer condition.
