Professional FAQ & Technical FAQ
1. What material is recommended for control arm on a vehicle in harsh conditions?
Forged high-strength steel (e.g., Q345/Q460) and heat-treated 7000/6000-series aluminum alloys are best for environments with frequent impact and corrosive exposure. Their microstructure offers both fatigue resistance and weight savings.
2. What is the typical thickness for a premium car front lower control arm?
Wall thickness usually ranges 3.8–6.2 mm, but high-stress applications (SUVs, trucks) benefit from 4.5+ mm and multi-wall extrusion for extra safety.
3. How do bushings affect control arm durability and NVH?
Bushings, typically EPDM or polyurethane, absorb vibrations and protect from metal-on-metal fatigue. High ShoreA value (>75) ensures stability while minimizing NVH (noise, vibration, harshness).
4. What installation and testing standards apply to control arm on a vehicle?
Installation is governed by ANSI/ISO 7116 and SAE J492 standards. Each arm is torque-checked and undergoes dynamic load testing (per ISO 6621) for at least 1 million cycles before shipment.
5. What is E-coating and why is it important?
E-coating (electrophoretic deposition) is an advanced anti-corrosion finish. It allows uniform, thin layers that provide up to 950-hour salt spray resistance while keeping tolerances tight—far surpassing classic powder paint in life expectancy.
6. What warranty and support does LK Control Arm provide?
A standard 3-year or 80,000km warranty, with in-depth failure analysis and rapid-replacement service for all B2B and B2C orders. Documentation includes test certificates and real-time tracking.
7. What vehicle models does the 54501-26000 arm cover?
Primarily Hyundai Santa Fe 2013–2020 models, but can also be adapted for certain Kia and Hyundai utility vehicles with compatible chassis codes.
