How To Choose The Right Undercar Parts For Your Vehicle

Your vehicle’s undercarriage is where performance, stability, and safety come together. From control arms and CV axles to hub assemblies and tie rods, undercar parts are critical to your vehicle’s structure and function. At GSP North America, we specialize in manufacturing suspension and drivetrain components that exceed OEM standards—so you get direct-fit reliability with upgraded strength. Choosing the right undercar parts can save you time, money, and future repairs. Here’s how to do it right.

Know What You're Replacing

Start by identifying exactly what part needs to be replaced. Common undercar components that wear over time include:

• CV Axles

• Control Arms

• Ball Joints

• Tie Rod Ends

• Hub Assemblies

• Sway Bar Links 

  
  

Each plays a specific role in steering, stability, and load support. Diagnosing the issue—whether it’s a torn boot, clunking noise, or alignment issue—will help ensure you get the correct replacement.

Understand the Importance of OE Fitment

Fitment is everything. A part that’s even slightly off-spec can create handling issues, premature wear, or worse—failure. That’s why GSP North America engineers each part as a direct replacement with OE-matched dimensions, mounting points, and tolerances.

Look for parts that specify compatibility with your vehicle's make, model, year, drivetrain layout, and engine size. Don’t rely on generic fits—exact fitment ensures safe installation and smooth operation.

Don’t Just Match the Part—Upgrade It

While many aftermarket brands focus on copying OEM specs, GSP takes it further. We design our components to be stronger than OEM, using upgraded materials, reinforced designs, and tighter quality control. This results in parts that not only restore your vehicle’s original performance but improve durability and longevity under real-world conditions.

For example:

• GSP CV Axles feature thermoplastic boots and high-performance grease to withstand extreme temperatures and articulation.

• GSP Hub Assemblies come pre-assembled with premium bearings to reduce friction and eliminate play.

• Control Arms are reinforced with forged steel and advanced coatings for maximum strength and corrosion resistance.

Consider Your Driving Conditions

Do you drive in harsh winters, off-road terrain, or high-mileage city traffic? Your replacement part should match your usage.

• Daily commuter: Opt for durable, maintenance-free components.

• Off-road or heavy load use: Choose reinforced parts built for added stress.

• Performance-oriented driver: Look for tighter tolerances and stiffer bushings for improved responsiveness.

GSP's catalog makes it easy to select the right parts for your driving style, giving you peace of mind and predictable performance.

Look for Trusted Brands with Real Testing

Not all undercar parts are built the same. Look for manufacturers that perform extensive testing on fit, function, and longevity. GSP North America parts undergo:

• Salt spray and corrosion testing

• Durability simulations

• Road testing under load We back our components with industry-leading warranties, so you know you're getting parts you can trust.

Installation Tips: Go the Extra Mile

When replacing undercar parts, inspect surrounding components for wear. A worn CV axle might also mean a fatigued control arm or a failing hub assembly. Replacing these at the same time can save labor costs and ensure a longer-lasting repair.

Also, torque fasteners to spec, align your suspension after installation, and use high-quality grease and hardware to avoid premature failure.
