Important 33mm Sway Bar Fitment
The supplied stabilizer bar is specified as 33mm in diameter.
Because GM used different suspension configurations across these platforms, verify the original sway bar before ordering.
Check:
- Year
- Make
- Model
- Trim
- FWD/AWD configuration where applicable
- Original stabilizer-bar diameter
- OE part number
This is especially important on the Pontiac Grand Prix, where the supplied fitment information references both 33mm and 34mm applications.
Replacement and Interchange Numbers
The front stabilizer bar cross-references:
927-100
10257316
10257317
10284146
10287717
10287944
10404184
10413385
25861193
25861194
25861195
25861196
20766790
Comparing the original OE number with this interchange list is recommended before ordering.
What’s Included?
The 927-100 kit includes:
- 1 × 33mm front sway bar
- 2 × front sway bar mounting bushings
- 2 × sway bar bushing brackets
- 4 × mounting screws
- Front sway bar end link kit
- Associated installation hardware
The advantage is straightforward: if you’re replacing a failed stabilizer bar on an older GM vehicle, you aren’t immediately reinstalling decades-old links and bushings around it.
Heavy-Duty Steel Construction
The replacement bar uses reinforced steel construction designed to withstand the torsional forces generated by the suspension.
A corrosion-resistant finish provides additional protection against exposure to:
- Water
- Road salt
- Dirt
- Mud
- Road debris
That’s particularly relevant considering the oldest applications for this kit are now approaching 30 years old.
What Does the Front Sway Bar Do?
The sway bar connects the left and right sides of the front suspension.
When the vehicle enters a corner, weight transfers toward the outside tires. The outside suspension compresses while the inside suspension unloads.
This difference twists the stabilizer bar.
The bar resists that twisting force and helps control excessive body roll.
A properly functioning stabilizer system contributes to:
- Reduced body roll
- Predictable cornering
- Better transitional stability
- More controlled lane changes
- Consistent suspension response
Symptoms of a Bad Sway Bar System
Potential symptoms include:
- Front suspension clunking
- Knocking over bumps
- Rattling
- Squeaking
- Excessive body roll
- Loose handling
- Worn end links
- Deteriorated sway bar bushings
- Bent stabilizer bar
- Severe corrosion
Keep in mind that the sway bar itself isn’t normally the first component to wear out.
End links and mounting bushings are much more common sources of clunking.
Included Sway Bar End Links
The kit includes replacement front end links.
These links connect the stabilizer bar to the suspension and transfer suspension movement into the bar.
Worn end links commonly produce:
- Clunking over small bumps
- Rattling on rough roads
- Excessive joint movement
- Reduced stabilizer-bar effectiveness
Replacing both links during installation provides a more complete stabilizer-system repair.
New Sway Bar Bushings and Brackets
Two mounting bushings and brackets are also included.
The bushings hold the center section of the sway bar against the chassis while allowing the bar to rotate as the suspension moves.
Worn mounting bushings can cause:
- Squeaking
- Clunking
- Excessive bar movement
- Delayed sway-bar response
Chevrolet Impala Fitment
This kit has particularly broad Impala coverage:
2000–2013 Chevrolet Impala
It also fits:
2014–2016 Chevrolet Impala Limited
2014–2016 Impala Limited Is Important
The word Limited isn’t optional here.
The Impala Limited continued using the previous-generation W-body platform after Chevrolet introduced the redesigned Impala.
Therefore:
2014–2016 Impala Limited — listed application
2014–2016 regular Impala — don’t assume fitment
This distinction should remain in your ProStreetOnline catalog data.
Chevrolet Monte Carlo Fitment
The supplied fitment specifies:
2001–2007 Chevrolet Monte Carlo
This is worth noting because some other 927-100 listings advertise 2000–2007 Monte Carlo coverage.
For this particular product listing, I’d use the manufacturer’s supplied 2001–2007 range unless you independently verify 2000 fitment.
That avoids turning broader interchange data into an unsupported application.
Buick Regal and Century Fitment
Compatible Buick applications include:
1997–2004 Buick Regal
1997–2005 Buick Century
Both are major W-body applications for this replacement sway bar.
Pontiac Grand Prix Fitment
The supplied application data lists:
1997–2003 Pontiac Grand Prix
and:
2006–2008 Pontiac Grand Prix
What About 2004–2005 Grand Prix?
I would not add them.
The supplied fitment specifically jumps from 2003 to 2006.
Even if another 927-100 product claims broader Grand Prix coverage, your catalog should follow the fitment data for the actual product you’re selling unless you’ve independently confirmed otherwise.
Buick Rendezvous and Pontiac Aztek
The crossover applications are:
2002–2007 Buick Rendezvous FWD
2001–2005 Pontiac Aztek FWD
Notice the FWD restriction.
Do not automatically extend the application to AWD models.
GM Minivan Applications
The kit also covers:
1997–2005 Chevrolet Venture FWD
1997–1998 Pontiac Trans Sport
1999–2001 Pontiac Montana
2002–2004 Pontiac Montana FWD
2005 Pontiac Montana Base
1997–2004 Oldsmobile Silhouette FWD
Exact drivetrain and trim qualifiers should remain attached to these applications.
Can a New Sway Bar Improve Handling?
If the original stabilizer system is worn or damaged, replacement can restore more predictable handling.
You may notice:
- Less unwanted body movement
- Better cornering stability
- More consistent steering response
- Reduced suspension noise
However, this is an OE-style replacement assembly, not necessarily a performance sway-bar upgrade.
Its primary job is restoring the suspension system to proper operation.
Installation
The kit is designed around the original mounting locations, but “bolt-on” doesn’t necessarily mean “effortless.”
Twenty-year-old GM suspension hardware occasionally has other plans.
General installation involves:
- Safely raise and support the vehicle.
- Inspect the entire front suspension.
- Disconnect both original end links.
- Support the original sway bar.
- Remove the mounting brackets and bushings.
- Remove the original bar.
- Compare the original and replacement components.
- Measure the original sway-bar diameter.
- Position the new 33mm bar.
- Install the supplied bushings and brackets.
- Install the new end links.
- Torque all hardware to factory specifications.
- Check steering and suspension clearance.
- Road-test.
- Reinspect all hardware.
Does Installation Require an Alignment?
Normally, no.
The stabilizer bar and links don’t directly establish:
- Camber
- Caster
- Toe
Replacing the sway bar assembly alone generally doesn’t require a wheel alignment.
