TRW JTC2340 Suspension Control Arm and Ball Joint Assembly Front Left Upper

The TRW JTC2340 is a front left upper suspension control arm and ball joint assembly, engineered as a direct OE-replacement unit for select Mopar applications. TRW — a ZF company and a globally recognized OEM supplier — manufactures this assembly to original equipment quality standards, ensuring a precise fit and reliable performance right out of the box.

A control arm is the hinged suspension link that connects the vehicle chassis to the suspension assembly that carries the wheel. Attached via a single pivot bushing, it maintains the correct radial position of the wheel while allowing controlled vertical movement. When the integrated ball joint or bushing wears out, replacing the entire control arm assembly is more efficient and cost-effective than servicing individual components separately.

Key Features:

• OE-Quality Construction: Manufactured using forged or cold-formed steel with a durable finish for long service life
• Integrated Ball Joint: Sealed, low-friction polymer bearing design enhances damping and reduces heat buildup
• Premium Dust Covers: High-quality rubber dust covers protect the ball joint from dirt and moisture intrusion
• Thermoplastic Bushings: High-quality thermoplastic control arm bushings provide flexibility and resistance to cracking for an extended lifespan
• Rigorous Testing: Every TRW part undergoes four levels of testing and technical/audit review, including endurance testing of 500,000 cycles before approval
• Performance Benefits: Advanced OE design helps contribute to improved fuel economy, reduced emissions, energy savings, driving comfort, and safety
• Direct-Fit Replacement: Engineered for straightforward installation with no modifications required

The TRW JTC2340 front upper control arm assembly restores your steering and suspension system to its original operating performance, delivering the low-friction, long-wear reliability you expect from an OEM-level supplier.
