TRW Automotive AfterMarket JTC1059 Track Control Arm

TRW Automotive AfterMarket JTC1059 Track Control Arm

TRW is a globally recognized name in automotive suspension components, known for precision engineering and durability. The JTC1059 Track Control Arm is an OEM‑grade replacement designed to restore the original geometry of the front suspension on a wide range of high‑performance vehicles.

Key Design Features

• High‑strength alloy construction – The arm is forged from a lightweight yet robust steel alloy that resists fatigue and maintains stiffness under extreme driving conditions.
• Precision machining – Tight tolerances ensure a perfect fit to the original mounting points, preserving wheel alignment and steering feel.
• Integrated bushings – The arm includes pre‑installed polyurethane bushings that reduce vibration and noise while providing smooth articulation during cornering.
• Corrosion protection – A protective coating resists rust and extends the service life even in harsh climates.

Compatibility Overview

The JTC1059 is engineered to fit a broad spectrum of front‑wheel vehicles, including:

• Audi Q7 (4L)
• Porsche Cayenne (9PA)
• Volkswagen Touareg (7LA, 7L6, 7L7)
• Other models within the VW/Audi/Porsche family that use the 7L0407021 series.

Each arm is available in left‑hand and right‑hand versions to match the vehicle’s side configuration. The part number JTC1059 corresponds to the OEM designation, ensuring seamless integration with factory components.

Installation Highlights

1. Remove the old control arm – Detach the existing arm by loosening the mounting bolts and disconnecting any associated tie‑rod or sway bar links.
2. Align the new arm – Position the JTC1059 so that its mounting holes line up precisely with the suspension frame. The pre‑installed bushings should sit flush against the chassis.
3. Tighten to specification – Use a torque wrench to secure the bolts to the manufacturer’s recommended values, ensuring optimal stiffness and preventing over‑tightening.
4. Recheck alignment – After installation, perform an alignment check to confirm that wheel angles remain within factory tolerances.

Performance Benefits

• Improved handling – By restoring the original track geometry, the JTC1059 enhances cornering stability and reduces body roll.
• Enhanced durability – The alloy construction withstands high loads, making it suitable for both daily driving and spirited performance sessions.
• Reduced maintenance – Integrated bushings eliminate the need for separate replacements, lowering long‑term upkeep costs.
• Consistent steering feel – The precise fit ensures that steering response remains unchanged from factory specifications.
