Understanding the Stabilizer Link on Your Classic Buick
On a 1950-1959 Buick Roadmaster, the front suspension was built for a smooth, commanding ride. The stabilizer bar link kit is a key part of that system. It's a relatively simple component, usually consisting of a rod, bushings, and washers, that connects the main stabilizer bar to the lower control arms on each side. Its purpose is to transfer force from one side of the suspension to the other during turns, which keeps the car from leaning or 'swaying' too much. Given the weight and size of a Roadmaster, these links work hard to keep the ride stable and prevent excessive body roll.
Symptoms of a Failing Stabilizer Bar Link
When stabilizer links wear out, they make their presence known. The most common sign is a distinct clunking or rattling noise from the front end, especially when driving over bumps or uneven roads. You might also notice your Roadmaster's handling feels 'loose' or less responsive, particularly in turns. The car may feel like it's wallowing or swaying more than usual, which can be unsettling. In severe cases, a completely broken link can make the car feel unstable, especially during sudden maneuvers.
Don't Ignore the Noise
That clunking sound is more than just an annoyance. It's a sign that a suspension component is loose. While you can usually still drive the car, a failed link compromises your handling and safety, reducing the effectiveness of the sway bar in controlling the car's body roll. This can be particularly dangerous in an emergency situation.
Choosing the Right Aftermarket Stabilizer Link Kit
For a vehicle from the 1950s, finding original "OEM" parts is nearly impossible. New Old Stock (NOS) parts are rare and expensive. Thankfully, modern aftermarket manufacturers produce stabilizer link kits that are often improvements over the original 1950s design, using more durable materials. The design for these Buicks is a simple bolt-and-bushing style, which is easy to replicate and improve.
Here’s a breakdown of the available brands based on general market reputation:
- Moog: Often considered a premium aftermarket brand, Moog is known for its "Problem Solver" line which sometimes features design improvements over original parts. However, some users feel their quality has become less consistent in recent years.
- Delphi: With a strong history as an Original Equipment supplier for many carmakers, Delphi parts are generally well-regarded for their quality and fit.
- Mevotech: Mevotech offers multiple tiers of quality. Their higher-end lines are often seen as good alternatives, though some users have mixed experiences with their standard-grade parts.
- Dorman: Dorman is known for making a vast range of replacement parts for many vehicles. Their quality can be hit-or-miss depending on the specific part, but they are a common choice for repairs.
- QuickSteer: Often positioned as a budget-friendly option, QuickSteer can be a viable choice if cost is the primary concern.
Pro Tip: Replace in Pairs
It is always recommended to replace stabilizer bar links in pairs (both left and right sides at the same time). If one has failed due to age and wear, the other is likely not far behind. Replacing both ensures balanced handling and saves you from doing the same job twice.

Frequently Asked Questions
Do I need a special type of link kit for my Roadmaster?
The 1950-1959 Roadmaster uses a simple bolt-style link with rubber grommets. Any kit listed as a direct fit for your specific year should work. The main differences between brands will be the quality of the metal hardware and the durability of the rubber or polyurethane bushings.
Is this a difficult part to replace myself?
For a DIY mechanic, this is generally an easy job. The most difficult part is often dealing with rust on the original nuts and bolts. You'll need basic hand tools, a jack, and jack stands. Soaking the old hardware in penetrating fluid beforehand is highly recommended. The suspension should be loaded (with the car's weight on it) to properly tighten the new links.
Were there any recalls or common issues with the stabilizer links on these cars?
Searches for official recalls or Technical Service Bulletins (TSBs) for a vehicle of this age are unlikely to yield results in modern databases. However, forums for classic Buick owners show that suspension noises are a common topic, often traced back to worn bushings and links throughout the suspension system. The simple design of the original links means they are a common wear item.
What is the difference between rubber and polyurethane bushings?
Most standard replacement kits will come with rubber bushings, similar to the original. Some premium or performance-oriented kits may offer polyurethane bushings. Polyurethane is firmer than rubber, which can lead to a slightly more responsive feel but may also transmit more road noise. For a classic car like the Roadmaster, rubber bushings are usually sufficient and maintain the original ride quality.
Technical Specifications
The original design consists of a link rod, spacer, retainers, and rubber grommets. The grommets are installed dry and the assembly is tightened to a specific dimension (approximately 1 11/16 inches between retainers) to ensure proper function.
