Suspension Strut Bellows for the 1997-2005 Buick Regal
This small, inexpensive boot is the only thing protecting your expensive struts from premature failure.
- The strut bellow's only purpose is to protect the expensive strut; if it's torn, the strut will fail.
- Replacing only the bellow is not cost-effective. If the bellow is bad, the entire strut assembly is likely worn and should be replaced as a complete 'quick strut' unit.
- For this generation of Regal, both KYB and Moog are quality aftermarket choices for this part, with Moog often having a better reputation for durability in forum discussions.
- A four-wheel alignment is mandatory after this job to prevent tire damage and handling problems.
Is Your Regal's Strut Bellow Torn?
A strut bellow doesn't have its own performance symptoms; the signs of failure are all visual. You won't feel a torn boot while driving, but you will absolutely feel the expensive strut failure that it causes down the road. The only way to know if your bellows are bad is to look at them.
- Visual Inspection: Look behind the wheel at the strut assembly. You should see a black, rubber or plastic accordion-like boot covering the metal strut rod. If this boot is cracked, ripped, or missing altogether, it needs to be replaced immediately. Often, this damage is discovered during a routine tire rotation or brake inspection.
- Consequences of a Torn Bellow: If the bellow has been torn for a while, you will start to notice the symptoms of a failing strut. These include a bouncy, uncontrolled ride, clunking noises over bumps, the front end diving when you brake, and uneven tire wear.

A Note on Replacement: The Bellows-Only Job is a Myth
Replacing only the strut bellow is almost never a good idea. The process requires removing the entire strut assembly from the car and using a dangerous tool called a spring compressor to disassemble it. The labor involved is identical to replacing the entire strut. If your 1997-2005 Regal has enough miles on it for the bellows to be rotten, the original struts are also at or near the end of their service life. It is far safer and more cost-effective to replace the entire unit with a 'quick strut' assembly, which includes a new strut, spring, mount, and bellow.

When you buy a complete strut assembly, it will come with a new bellow. However, if you are having struts assembled at a shop, 🎬 Watch: How to change a strut cartridge on this platform. you will need to supply the bellows. For your Regal, KYB and Moog are the primary aftermarket options.
- KYB (SB127): KYB is a top-tier manufacturer of struts, but their accessory components like mounts and bellows receive mixed reviews in forums. While they are a well-known brand, some users have noted the material may not be as robust as other options.
- Moog (K90463): Moog has a strong reputation as a 'problem solver' in the aftermarket, often engineering parts to be more durable than the original. Forum discussions generally favor Moog for components like mounts and bellows, considering them a reliable and high-quality choice.
Pro Tip: For a wear item like a bellow, both KYB and Moog are reputable choices. However, based on community feedback, Moog often has a slight edge in perceived durability for these non-strut suspension components. Given the critical function and the minimal price difference, choosing the part with the better reputation is a smart move.

Frequently Asked Questions (FAQ)
Is a strut bellow the same as a strut boot?
Yes, the terms 'strut bellow' and 'strut boot' (or dust boot) are used interchangeably. They refer to the same protective cover on the strut rod.
Can I reuse my old bellows on new struts?
No, this is a terrible idea. The old bellow is made of the same age-worn rubber or plastic that has likely become brittle. Reusing it puts your brand new, expensive strut at immediate risk. Always use the new bellow that comes with your new strut assembly or buy a new one.
What happens if I just ignore a torn strut bellow?
A torn bellow allows dirt and moisture to attack the strut's piston rod and seal. This will scratch the rod and destroy the seal, causing the strut's internal fluid to leak out. The strut will lose its ability to control bumps, leading to a bouncy, unsafe ride and the need for a complete strut replacement.
Do I need a wheel alignment after replacing the bellows?
Yes, absolutely. To replace the bellow, the strut must be disconnected from the steering knuckle. Any time this connection is loosened on the front of your Regal, a full four-wheel alignment is required to prevent bad handling and rapid tire wear.
Are there any recalls for the 1997-2005 Regal's strut bellows?
No, there are no NHTSA safety recalls specifically for the strut bellows on the 1997-2005 Buick Regal. Failure is a result of normal aging and wear. While some later model year Regals had recalls for rear suspension links, these do not apply to the 1997-2005 generation's struts.
