Suspension Stabilizer Bar Bushing Kits for the 1965-1969 Buick Full-Size Platform
A guide to stabilizer bar bushings for your classic Buick, clarifying a common model misconception.
- The Buick Roadmaster was not made from 1965-1969; verify if you have a LeSabre, Wildcat, or Electra before buying parts.
- Aftermarket stabilizer bushing kits are readily available and the primary source for these classic vehicles.
- Choose between standard rubber bushings for an original ride feel or firmer polyurethane for improved handling.
- Due to the vehicle's age, expect original rubber bushings to be completely degraded and plan for potentially rusted bolts during replacement.
A Note on the Buick Roadmaster
Before purchasing parts, it's important to correctly identify your vehicle. The Buick Roadmaster was not produced between 1965 and 1969. The classic era for the Roadmaster ended in 1958, and the name was later revived for a different model from 1991 to 1996. If you own a full-size Buick from the 1965-1969 timeframe, you likely have a LeSabre, Wildcat, or Electra. Please verify your car's model using your registration or vehicle emblems before ordering parts.
Symptoms of Failing Stabilizer Bar Bushings
On a large, heavy car like a 1960s Buick, the symptoms of worn stabilizer bar bushings are often noticeable. You may hear a clunking or rattling sound from the front suspension, especially when driving over bumps. The vehicle may also exhibit excessive body roll and feel less stable when cornering. A visual inspection might reveal cracked, brittle, or missing bushings where the sway bar connects to the frame and end links.
Choosing the Right Aftermarket Bushing Kit
For these classic models, new original equipment manufacturer (OEM) parts are generally not available. The aftermarket is the primary source for suspension components. Fortunately, aftermarket quality for these parts is typically reliable. Your main choice will be the material of the bushings.
- Standard Replacement (Rubber): Bushings made from rubber will provide a ride quality similar to the car's original feel. Brands like Mevotech and ACDelco offer dependable standard replacement kits. These are a good choice for owners seeking to maintain the car's original characteristics.
- Performance Upgrade (Polyurethane): Polyurethane is a firmer material than rubber. Kits from brands like Energy Suspension use polyurethane to provide a more responsive feel. This reduces the time it takes for the stabilizer bar to engage, resulting in less body roll and sharper handling. While some drivers may notice a slight increase in ride stiffness, this is a popular upgrade for classic cars.

Frequently Asked Questions
Are there any recalls for 1965-1969 Buick stabilizer bushings?
No, there are no specific recalls or Technical Service Bulletins (TSBs) related to stabilizer bar bushings for these Buick models. However, due to the age of these vehicles, the original rubber components are almost certainly degraded and in need of replacement.
Is it difficult to replace stabilizer bar bushings?
Replacement is generally straightforward for a DIY mechanic with basic tools. The most common difficulty is dealing with rusted or seized bolts due to the age of the vehicle. Using penetrating oil and having a breaker bar on hand is recommended. The estimated time for replacement is typically 1-2 hours.
Should I choose rubber or polyurethane bushings?
Choose rubber if you want to maintain the original, softer ride quality of your Buick. Choose polyurethane if you want to improve handling and reduce body roll, and you don't mind a potentially firmer ride. Polyurethane is also more resistant to degradation from oils and road grime.
Do I need to lubricate the new bushings?
Yes, especially if you are installing polyurethane bushings. Most kits come with a special silicone-based grease. Applying this grease during installation is essential to prevent squeaking and ensure a long service life.
Technical Specifications
Bushings are typically available in rubber or polyurethane. Kits include frame-mount bushings and sometimes end-link bushings. Bushing diameter must match the vehicle's specific sway bar.
