Product Overview
Upgrade your vehicle's front-end performance with this premium suspension kit. Engineered as a direct-fit replacement, this kit restores factory ride quality, steering precision, and handling. Whether you're refreshing a high-mileage daily driver or rebuilding after wear, these control arms and components deliver OE-grade performance at a fraction of dealership pricing.
Each component is manufactured to strict quality standards with precision-machined ball joints, high-durometer rubber bushings, and corrosion-resistant coatings. The result is a suspension system that handles just like factory — smooth, quiet, and predictable through every corner and over every bump.
Key Features

Why Choose iFJF Control Arms?
Dealership replacement parts can cost 3-5x more for the same performance. Our suspension components are sourced from ISO/TS 16949 certified manufacturers — the same supply chain that produces OE parts for major automakers. You get factory-quality parts without the factory price tag.
Every control arm kit undergoes dimensional verification and ball joint articulation testing before packaging. We stand behind every product with a 1-year warranty and lifetime technical support. If it doesn't fit or perform, we'll make it right.
Frequently Asked Questions
Q: Will these control arms fit my vehicle?
A: Check the compatibility table above. These parts are designed for the specific years, makes, and models listed. If your vehicle falls outside these ranges, please contact us with your VIN for verification before ordering.
Q: Do I need an alignment after installing control arms?
A: Yes — absolutely. Replacing control arms changes suspension geometry and toe settings. A professional wheel alignment is required immediately after installation to prevent uneven tire wear and ensure proper handling. Budget approximately $80-120 for this service.
Q: Can I install these myself or do I need a mechanic?
A: Experienced DIYers with proper tools can install control arms in 2-4 hours per side. You'll need a floor jack, jack stands, torque wrench, ball joint separator, and basic hand tools. If you're not comfortable with suspension work, we recommend professional installation (typically 2-3 hours labor per side).
Q: How do I know if my control arms need replacement?
A: Common signs include: clunking noises over bumps, steering wheel vibration, uneven tire wear, wandering steering, and visible bushing cracks. If your vehicle has over 80,000 miles on original suspension components, preventive replacement is recommended.
Q: Are ball joints pre-installed and greased?
A: Yes. All control arms come with ball joints pre-installed and pre-greased from the factory. They are ready to bolt on and drive — no additional assembly required.
Q: What's the difference between this kit and individual OEM parts?
A: Our complete kit includes all the components you'd typically buy separately at the dealership — control arms, ball joints, and bushings — in one package at a significantly lower total cost. Individual OEM parts can easily exceed $500+ per side; our kit provides comparable quality for 40-60% less.
Q: How long do aftermarket control arms typically last?
A: With proper installation and alignment, expect 60,000-100,000+ miles of service life. Lifespan depends on driving conditions — rough roads, potholes, and off-road use accelerate wear. Regular inspection every 30,000 miles is recommended.
Q: Do you offer warranty on control arm kits?
A: Yes — all iFJF control arm kits include a 1-year limited warranty against manufacturing defects. If you experience any quality issues, contact our support team for a replacement or refund.
