Important Fitment Information
This is listed as a 33mm front stabilizer bar, but some applications—particularly certain Pontiac Grand Prix configurations—may use a 34mm bar.
Before ordering, verify:
- Model year
- Trim
- Drivetrain
- Original sway-bar diameter
- OE part number
That last check is worth doing. GM built enough variations of these platforms to ensure “it’s an Impala, it’ll fit” eventually becomes an expensive sentence.
Replacement Part Numbers
The Dasbecan sway bar cross-references:
927-100
10257316
10257317
10284146
10287717
10287944
10404184
10413385
25861193
25861194
25861195
25861196
20766790
These numbers can be used to help confirm compatibility with the original stabilizer bar.
What Does the Front Sway Bar Do?
The front sway bar—also called a stabilizer bar or anti-roll bar—connects the left and right sides of the front suspension.
During cornering, the outside suspension compresses while the inside suspension unloads.
The sway bar twists and resists this difference in suspension movement.
That helps control:
- Body roll
- Cornering stability
- Steering response
- Rapid lane changes
- Transitional handling
Symptoms of a Bad Front Sway Bar System
Common symptoms include:
- Clunking over bumps
- Excessive body roll
- Loose handling
- Poor steering response
- Squeaking or knocking
- Damaged sway bar
- Corroded mounting areas
- Deteriorated bushings
- Worn end links
Keep in mind that the bar itself doesn’t commonly wear like a bushing or ball joint.
If the original bar isn’t bent, broken or badly corroded, inspect the bushings and end links carefully before condemning the entire stabilizer bar.
Why Replace the Sway Bar?
A complete stabilizer-bar replacement may become necessary because of:
- Severe corrosion
- Collision damage
- Bent bar
- Cracked or damaged mounting areas
- Structural failure
- Previous incorrect repair
The Dasbecan replacement uses the original mounting locations to simplify installation.
33mm Diameter
The bar is specified at approximately 33mm in diameter.
Bar diameter matters because even a small difference in diameter can substantially affect torsional stiffness.
Don’t assume a 33mm replacement is automatically interchangeable with every visually similar GM sway bar.
Measure the original bar at a clean, straight section away from bends and damaged areas.
Chevrolet Impala Applications
The primary application is:
2000–2013 Chevrolet Impala
The bar also fits:
2014–2016 Chevrolet Impala Limited
Impala Limited vs. Impala
This distinction matters.
The 2014–2016 Impala Limited continued using the older W-body architecture.
The redesigned 2014+ retail Impala was a different platform.
For your catalog, always retain the word Limited for the 2014–2016 application.
Chevrolet Monte Carlo
Fitment includes:
2000–2007 Chevrolet Monte Carlo
The Monte Carlo shares substantial suspension architecture with contemporary W-body Impala applications.
Pontiac Grand Prix
Listed fitment includes:
1997–2003 Pontiac Grand Prix
and:
2006–2008 Pontiac Grand Prix
Some applications may use a different sway-bar diameter, so this is one vehicle where measuring the original bar is especially worthwhile.
Buick Regal and Century
Applications include:
1997–2004 Buick Regal
1997–2005 Buick Century
These older W-body applications are increasingly likely to require suspension restoration simply because of age.
Buick Rendezvous and Pontiac Aztek
The 927-100 application also includes select:
2002–2007 Buick Rendezvous FWD
2001–2005 Pontiac Aztek FWD
Verify drivetrain before ordering.
GM Minivan Applications
The bar is also listed for several GM front-wheel-drive minivans:
1997–2005 Chevrolet Venture
1997–1998 Pontiac Trans Sport
1999–2005 Pontiac Montana applications
1997–2004 Oldsmobile Silhouette
Check the exact year, trim and suspension configuration before installation.
Direct-Replacement Installation
The Dasbecan bar is designed around factory mounting locations.
General installation includes:
- Safely raise and support the vehicle.
- Inspect the existing stabilizer system.
- Disconnect the front sway bar end links.
- Support the original sway bar.
- Remove the sway-bar mounting brackets.
- Remove the original stabilizer bar.
- Compare its shape and diameter with the replacement.
- Inspect or replace the mounting bushings.
- Position the new bar.
- Reinstall the mounting brackets.
- Reconnect the end links.
- Torque hardware to factory specifications.
- Check suspension and steering clearance.
- Road-test.
- Reinspect the installation.
Installation difficulty varies considerably by application, corrosion and available working space.
Inspect the End Links and Bushings
When replacing the stabilizer bar, inspect the:
- Sway bar end links
- Mounting bushings
- Mounting brackets
- Fasteners
Installing a new bar with destroyed 25-year-old bushings isn’t much of a restoration.
It’s more of a suspension hostage negotiation.
Does Installation Require an Alignment?
Normally, replacing the sway bar doesn’t alter:
- Camber
- Caster
- Toe
Therefore, an alignment usually isn’t required solely because the stabilizer bar was replaced.
