The General Motors G-body platform (1978-1988) is a classic among muscle car enthusiasts, known for its sleek design and potent engine options. However, the stock suspension often leaves something to be desired in terms of handling and performance. This is where tubular control arms come in. These aftermarket components offer significant advantages over their factory counterparts, transforming the driving experience of your G-body. This guide will delve into the specifics of G-body tubular control arms, addressing common questions and concerns.
What are Tubular Control Arms?
Tubular control arms are a performance upgrade replacing the stock stamped steel control arms. Instead of heavy, stamped steel, they utilize lightweight, high-strength tubing, typically chromoly steel. This results in a significant reduction in unsprung weight, leading to improved handling, acceleration, and braking. The stronger construction also allows for improved geometry adjustments, further enhancing performance.
Why Upgrade to Tubular Control Arms on My G-Body?
The benefits extend beyond mere weight reduction. Tubular control arms provide:
-
Improved Handling: Reduced unsprung weight translates to quicker steering response, reduced body roll, and improved overall handling characteristics. The stiffer construction minimizes flex under load, further refining the car's responsiveness.
-
Enhanced Performance: Less weight means quicker acceleration and improved braking performance. Every pound saved at the wheels makes a noticeable difference.
-
Increased Adjustability: Tubular control arms often offer greater adjustability for caster, camber, and pinion angle. This allows for fine-tuning the suspension geometry for optimal performance based on individual preferences and driving conditions.
-
Increased Durability: While weight is reduced, the high-strength tubing is significantly more durable than the stock stamped steel, resisting bending and fatigue under stress.
What are the Different Types of G-Body Tubular Control Arms?
Several manufacturers produce tubular control arms for G-bodies, each with slight variations in design and features. Some key differences include:
- Material: Most are chromoly steel, but some may use other high-strength alloys.
- Construction: Some feature welded joints, while others are fabricated as single pieces for maximum strength.
- Adjustability: The range of adjustment available for caster and camber can vary between manufacturers and models.
- Additional Features: Some may include features like spherical bearings or upgraded bushings for further performance improvements.
How Much Do G-Body Tubular Control Arms Cost?
The cost varies depending on the manufacturer, materials, and features. Expect to pay anywhere from a few hundred dollars to over a thousand dollars for a complete set (upper and lower control arms). The price reflects the quality of materials, construction, and adjustability.
Are Tubular Control Arms Difficult to Install?
Installing tubular control arms typically requires some mechanical aptitude and the right tools. While it's not an overly complex job, it's not a weekend project for beginners. Consult professional installation if you are unsure about undertaking the job yourself. Improper installation can lead to compromised safety and performance.
What Other Suspension Upgrades Should I Consider with Tubular Control Arms?
For optimal results, consider upgrading other suspension components alongside your tubular control arms. This could include:
- Coil-over shocks: Provide better adjustability and ride quality.
- Sway bars: Reduce body roll and improve handling.
- Bushings: Upgraded bushings improve the precision and feel of the suspension.
Conclusion
Upgrading to tubular control arms is a significant step towards transforming your G-body's handling and performance. The benefits of reduced weight, increased adjustability, and enhanced durability make them a worthwhile investment for any serious G-body enthusiast. Remember to research different manufacturers, compare features, and choose the set that best suits your needs and budget. Always prioritize safety and ensure proper installation.
