The General Motors G-body platform, encompassing iconic models like the Buick Regal, Oldsmobile Cutlass, Pontiac Grand Prix, and Chevrolet Monte Carlo, remains a popular choice for enthusiasts. A key area of upgrade for these classic cars is the suspension, and specifically, the control arms. Many owners opt for tubular control arms to improve handling, reduce weight, and enhance the overall driving experience. This guide delves into the world of G-body tubular control arms, exploring their benefits, considerations, and installation.
What are G-Body Tubular Control Arms?
Standard G-body control arms are typically constructed from stamped steel. Tubular control arms, on the other hand, are fabricated from lightweight, high-strength steel tubing. This design change offers several advantages, as we'll explore below. They replace the factory stamped steel arms, providing a significant upgrade for performance-oriented drivers and those seeking improved handling characteristics.
What are the Benefits of Tubular Control Arms for G-Bodies?
The advantages of upgrading to tubular control arms on your G-body are numerous:
-
Reduced Un-sprung Weight: Tubular arms are significantly lighter than their stamped steel counterparts. This reduction in unsprung weight translates to improved handling, quicker response to steering inputs, and a more comfortable ride, especially over uneven surfaces. Less weight means less force needed to accelerate and decelerate the suspension components.
-
Increased Strength and Durability: While lighter, tubular control arms are often stronger than stock arms. The design allows for more efficient load distribution, resulting in increased resistance to bending and twisting under stress. This improved durability is particularly beneficial for performance driving and modified vehicles.
-
Improved Handling and Performance: The combined effects of reduced unsprung weight and increased strength lead to a noticeable improvement in handling. The car will respond more accurately to steering inputs, exhibiting less body roll in corners, and providing a more precise and controlled driving experience.
-
Enhanced Aesthetics: Many enthusiasts appreciate the cleaner and more aggressive look of tubular control arms. They offer a visual upgrade that complements performance modifications and enhances the overall appearance of the undercarriage.
What are the Different Types of G-Body Tubular Control Arms?
Several manufacturers offer tubular control arms for G-bodies, each with its own design nuances and features. Some key differences include:
-
Material: While most are made from steel tubing, some manufacturers may offer different grades or treatments for improved strength or corrosion resistance.
-
Bushings: The type and quality of bushings used significantly impact handling and suspension performance. Polyurethane bushings are a common upgrade, offering increased durability and reduced deflection compared to rubber bushings.
-
Adjustability: Some tubular control arms offer adjustable features, allowing for fine-tuning of caster and camber settings to optimize handling and alignment.
How Much Do G-Body Tubular Control Arms Cost?
The price of G-body tubular control arms varies depending on the manufacturer, features, and material. Expect to pay anywhere from a few hundred to over a thousand dollars for a complete set (front and rear). The cost often reflects the quality of materials, construction, and features offered.
Are Tubular Control Arms Difficult to Install?
Installing tubular control arms requires mechanical aptitude and the right tools. While generally considered an intermediate-level modification, it is not a task for novice mechanics. Improper installation can compromise handling, alignment, and even safety. Refer to manufacturer instructions and seek professional assistance if needed.
What Other Suspension Upgrades Should I Consider with Tubular Control Arms?
For optimal performance, consider pairing tubular control arms with other suspension upgrades such as:
- Coil-over shocks: Provide adjustable ride height and damping for fine-tuned handling.
- Sway bars: Reduce body roll and improve stability during cornering.
- Performance bushings: Enhance handling precision and reduce deflection.
- Bracing: Reinforce the chassis and improve stiffness.
Conclusion
Upgrading to tubular control arms is a significant step towards improving the handling and performance of your G-body. The reduced weight, increased strength, and enhanced aesthetics make them a popular choice among enthusiasts. However, careful consideration of cost, installation, and complementary upgrades is crucial for achieving optimal results. Remember always to consult professional mechanics if you are unsure about any aspect of the installation process.
