TRW JSB4120S Suspension Strut Mount Front Upper

The TRW JSB4120S is a front suspension strut mount engineered as a direct OE-quality replacement. Strut mounts serve as the critical connection point between the top of the strut assembly and the vehicle body, isolating road vibration and noise from the cabin while allowing the strut to rotate smoothly during steering.

Key Features:

• OE-Quality Construction: Manufactured to meet or exceed original equipment specifications using high-quality materials
• Vibration & Noise Reduction: Designed to reduce road noise, harshness, and vibration transmitted into the vehicle cabin
• Precision Fit: Direct-fit replacement engineered to restore proper strut alignment and bearing function
• Rigorous Testing: Validated through on-road and laboratory testing to ensure safety and durability
• No Remanufactured Components: Built entirely from new materials — not a remanufactured part
• Cross-Reference: Interchanges with OEM part numbers 4A0 412 377 A, 4A0 412 377 B, and 4A0 412 377 C

TRW is a global leader in automotive safety systems, and every suspension part in their lineup is produced to stringent vehicle manufacturer quality standards. The JSB4120S strut mount restores proper suspension geometry, eliminates clunking or creaking from worn mounts, and helps return the ride and handling to like-new performance.
