Prothane 7-511-BL GM J-Body Engine Lower Torque Strut Bushing Kit Black

The Prothane 7-511-BL is a polyurethane engine lower torque strut bushing kit designed as a direct replacement for GM J-Body platforms spanning model years 1995–2004, including the Chevrolet Cavalier and Pontiac Sunfire. This kit replaces the factory rubber bushings that deteriorate over time, causing excessive engine movement, driveline slop, and imprecise throttle response.

Prothane's polyurethane formulation is significantly more durable than OEM rubber, resisting oil, heat, and road grime that typically accelerate rubber bushing failure. By reducing unwanted engine torque movement, these bushings help restore crisp, predictable power delivery and reduce drivetrain vibration and clunking under acceleration.

Key Features:

• Manufactured from Prothane's high-durometer polyurethane compound for extended service life
• Black (BL) finish — also available in red
• Direct OEM replacement geometry — no modifications required for installation
• Resists degradation from oil, heat, and environmental exposure
• Reduces engine torque movement for improved throttle response and drivetrain feel
• Includes all necessary hardware and Prothane's grease packet for proper installation
• Made in the USA

The Prothane 7-511-BL engine lower torque strut bushing is an ideal upgrade for daily drivers and performance builds alike, delivering a noticeable improvement in drivetrain tightness over worn or cracked factory rubber bushings.
