Important 33mm Fitment Requirement
This A-Premium assembly uses a 33mm front stabilizer bar.
Before ordering, verify the diameter of the original sway bar, especially on applications that were available with different suspension packages.
Check:
- Year
- Make
- Model
- Trim
- Drivetrain
- Original sway-bar diameter
- OE part number
Don’t select a sway bar based solely on vehicle model.
Part Numbers and Interchange Numbers
The A-Premium assembly cross-references:

Matching one of these numbers to the original application can provide another layer of fitment verification.
Specifications

What’s Included?
The A-Premium kit includes:
- 1 × 33mm front U-shaped stabilizer bar
- 2 × front sway bar end links
- 2 × front mounting brackets
- 1 × mounting hardware set
This provides a more complete repair than purchasing the stabilizer bar alone.
What Does a Front Sway Bar Do?
The stabilizer bar—also known as the sway bar or anti-roll bar—connects the left and right sides of the suspension.
During cornering, the outside suspension compresses while the inside suspension unloads.
This difference twists the stabilizer bar.
The bar resists that twisting motion, helping control excessive body roll and keeping chassis movement more predictable.
A properly functioning front stabilizer system contributes to:
- Body-roll control
- Cornering stability
- Steering response
- Highway stability
- More predictable emergency maneuvers
Symptoms of a Bad Sway Bar System
Potential symptoms include:
- Clunking over bumps
- Knocking from the front suspension
- Squeaking
- Excessive body roll
- Loose handling
- Broken sway bar
- Bent stabilizer bar
- Corroded mounting areas
- Deteriorated bushings
- Worn end links
The sway bar itself doesn’t typically “wear out” like a ball joint.
If the bar isn’t bent, cracked or badly corroded, inspect the links and bushings before replacing the entire assembly.
Included Front Sway Bar End Links
This kit includes two replacement front stabilizer links.
End links connect the stabilizer bar to the suspension. Wear in their joints can create unwanted movement and produce a noticeable clunk over rough pavement.
Replacing both links while installing the new bar helps eliminate another potential source of suspension noise.
Chevrolet Impala Fitment
One of the most important applications is:
2000–2013 Chevrolet Impala
The kit also fits:
2014–2016 Chevrolet Impala Limited
2014–2016 Impala Limited Warning
For 2014–2016, fitment is specifically for the Impala Limited, which continued using the older W-body platform.
Do not automatically list this sway bar for the redesigned regular 2014–2016 Chevrolet Impala.
For your catalog:
2014–2016 Chevrolet Impala Limited — YES
2014–2016 Chevrolet Impala — DO NOT ASSUME
That distinction is important.
Chevrolet Monte Carlo Fitment
The A-Premium 927-100 is listed for:
2000–2007 Chevrolet Monte Carlo
These W-body coupes share substantial underlying suspension architecture with contemporary Impala applications.
Pontiac Grand Prix Fitment
Listed Grand Prix applications are:
1997–2003 Pontiac Grand Prix
and:
2006–2008 Pontiac Grand Prix
Notice the 2004–2005 gap in the supplied application data.
I would not list 2004–2005 Grand Prix unless A-Premium or another authoritative catalog specifically confirms those years.
The seller also references a 34mm diameter on some Grand Prix applications, making original-bar measurement especially important.
Buick Regal Fitment
Compatible applications include:
1997–2004 Buick Regal
These W-body Regals are another important application for the 927-100 assembly.
Buick Century Fitment
The kit is also listed for:
1997–2005 Buick Century
On these older vehicles, inspect the entire stabilizer system rather than assuming the bar itself is responsible for suspension noise.
Pontiac Aztek and Buick Rendezvous
Crossover applications include:
2001–2005 Pontiac Aztek FWD
2002–2007 Buick Rendezvous FWD
The FWD qualifier matters, so it should remain in your catalog fitment data.
GM Minivan Fitment
The A-Premium 927-100 also covers several GM minivans:
- 1997–2005 Chevrolet Venture FWD
- 1999–2001 Pontiac Montana
- 2002–2004 Pontiac Montana FWD
- 2005 Pontiac Montana Base
- 1997–1998 Pontiac Trans Sport
- 1997–2004 Oldsmobile Silhouette FWD
Verify drivetrain and suspension configuration before ordering.
Steel Construction
The stabilizer bar uses steel construction with a black corrosion-resistant surface finish.
That’s important because the bar is constantly exposed to:
- Rain
- Road salt
- Dirt
- Water
- Gravel
- Temperature changes
Corrosion becomes increasingly relevant on vehicles from the late 1990s and early 2000s.
Installation
General replacement involves:
- Safely raise and support the vehicle.
- Inspect the complete front suspension.
- Disconnect both sway bar end links.
- Support the original stabilizer bar.
- Remove the mounting brackets.
- Remove the original sway bar.
- Compare its dimensions and shape with the A-Premium replacement.
- Measure the original bar diameter.
- Position the replacement stabilizer bar.
- Install the supplied brackets and hardware.
- Install both new end links.
- Torque all hardware to factory specifications.
- Check suspension and steering clearance.
- Road-test.
- Reinspect the installation.
Does Sway Bar Replacement Require an Alignment?
Normally, no.
The sway bar and end links don’t directly establish:
- Camber
- Caster
- Toe
Therefore, replacing the stabilizer bar by itself generally doesn’t require an alignment.
