Absolutely. Modern aluminum control arms vs steel isn’t a question of strength – it’s about choosing the right tool for the job. Today’s forged aluminum control arms easily handle daily driving forces. The material’s high strength-to-weight ratio means you get plenty of durability along with the performance benefits of reduced weight.
Aluminum vs Steel Control Arms: Which One Is Right for You?
Making the switch to aftermarket control arms can enhance your vehicle’s handling. But when it comes to aluminum vs steel control arms, which material delivers the performance you need? Let’s cut through the marketing hype and get straight to the facts about these crucial suspension components.
The Real Story: Aluminum Control Arms vs Steel
Your control arms connect your wheels to your chassis, handling every bump, turn, and launch. Consider these factors when deciding between aluminum vs steel control arms:
Vehicle Weight: Heavier vehicles might benefit from steel’s strength, while lighter cars can maximize aluminum’s benefits.
Driving Style: Hard launches and aggressive driving might favor steel’s durability. Regular street driving and autocross could benefit more from aluminum’s responsiveness.
Climate: Wet weather and road salt make aluminum’s corrosion resistance more valuable.
At Aldan American, we’ve seen firsthand how the right control arms can transform a vehicle’s performance. Here’s what you need to know about both materials to make the right choice for your ride.
The Steel Advantage
When you’re comparing steel vs aluminum control arms, steel brings some serious muscle to the table. These workhorses of the suspension world offer:
Raw Strength: Steel control arms laugh at abuse. They handle repeated stress without flinching, making them ideal for heavy vehicles and high-power applications.
Budget-Friendly: Steel typically costs less than aluminum, giving you more bang for your buck when you’re building your suspension setup.
Heat Tolerance: Steel shrugs off heat like a champ. For drag racing applications where brake heat can cook nearby components, that matters.
The Aluminum Edge
Modern aluminum control arms have several key advantages:
Weight Reduction: Aluminum cuts unsprung weight dramatically, letting your suspension react faster to road changes. Less weight means better handling and improved performance.
Corrosion Resistance: While steel can rust, aluminum naturally resists corrosion. For street-driven vehicles that see rain, snow, and road salt, this means longer life with less maintenance.
Heat Dissipation: Aluminum disperses heat faster than steel, helping keep your entire suspension system running cooler during hard driving.
Real-World Performance
When you’re comparing aluminum vs steel control arms, your driving style matters more than specs on paper. Here are a few things to consider:
Street Performance: Both materials excel here, but aluminum’s weight savings can sharpen your car’s responses. Our tubular designs, whether aluminum or steel, improve suspension geometry while maintaining easy, bolt-on installation.
Track Use: For road course work, aluminum’s weight reduction helps your suspension respond faster. Steel might be your go-to for drag racing, where launch forces put maximum stress on components.
Show Cars: Aluminum’s corrosion resistance and clean looks make it a show favorite. Our precision-engineered control arms deliver that aggressive stance without sacrificing functionality.
Installation and Maintenance Considerations
Whichever material you choose, today’s control arms offer straightforward installation. Our selection includes:
- Direct bolt-on designs
- No cutting or welding required
- OEM-like fitment
- Complete mounting hardware
Making The Right Choice: Real-World Scenarios
Real-world scenarios tell the story better than specs alone. Let’s look at some common builds and what typically works best for each situation.
Take a modern Mustang GT that sees regular street duty with occasional track days. This is where aluminum shines. The reduced unsprung weight helps the suspension respond faster to surface changes, and that matters when you’re pushing hard through corners at your local road course. Plus, these cars already pack enough weight up front with that Coyote V8 – any chance to trim weight from the suspension pays dividends in handling.
Now consider a classic Chevelle packing big-block power. Steel control arms might be your best bet here. That heavy engine up front puts serious stress on suspension components, especially during hard launches. Steel’s natural strength and durability stand up to the abuse, while its lower cost leaves room in the budget for other performance upgrades.
Daily drivers in the Salt Belt face their own challenges. Take a late-model Dodge Challenger running year-round in Michigan. Here, aluminum’s corrosion resistance becomes a major selling point. While steel arms can eventually succumb to rust despite protective coatings, aluminum keeps fighting corrosion year after year, saving you from future headaches and replacement costs.
For autocross warriors, weight is everything. A Camaro running in a competitive class needs every advantage it can get. Aluminum control arms not only reduce unsprung weight but also help with overall weight distribution. Less weight at the corners means faster direction changes and better acceleration out of tight corners. The improved heat dissipation also helps maintain consistent performance throughout a long day of runs.
Aluminum Vs Steel: The Bottom Line
Both aluminum and steel control arms can deliver exceptional performance when properly engineered. At Aldan American, we’ve partnered with top manufacturers like Spohn Performance, SPC, and Performance Online to offer you the best in both materials.

Aluminum vs Steel Control Arms FAQs
Are aluminum control arms strong enough for street use?
Will steel control arms rust even with protective coating?
Over time, steel can develop surface rust, especially in areas with harsh winters and road salt. While protective coatings help significantly, they can eventually wear or chip. That’s one reason many drivers opt for aluminum lower control arms vs steel in regions where corrosion is a concer
How much weight difference is there between aluminum and steel control arms?
When comparing steel vs aluminum control arms, the weight savings can be significant. Typically, aluminum control arms weigh 40-50% less than their steel counterparts. For a complete set of upper and lower control arms, this could mean a reduction of several pounds per corner – weight that comes directly off your suspension’s moving mass.
Do I need to modify my suspension for aftermarket control arms?
Not with our offerings. Whether you choose aluminum or steel, our control arms are engineered for direct bolt-on installation. They work with factory mounting points and maintain proper suspension geometry while offering improved performance characteristics.
What maintenance differences are there between aluminum and steel control arms?
Steel control arms might need occasional inspection for rust and may require protective coating touch-ups over time. Aluminum control arms vs steel have an advantage here – they naturally resist corrosion and typically need only regular bushing inspection and basic cleaning to maintain their performance.
