ECS Rear Differential Mount Bushing Insert Kit – ES#3161730

ECS Tuning’s Performance Rear Differential Mount Bushing Insert Kit offers a more engaging driving experience, with crisper throttle response and reduced driveline slop without increasing cabin NVH.

The ECS Tuning performance rear differential mount insert kit was engineered in-house by our industry leading R&D department, resulting in countless hours of research and testing to establish the best possible design for minimizing driveline deflection while retaining the vehicles everyday driving comfort. ECS Tuning’s primary goal was to achieve a comfortable and compliant ride while maximizing performance, and real world test miles put down on multiple vehicles has proven just that.

Features include:

• Reduction in rear differential movement
• 6061-T6 Billet inserts for deflection resistance and durability, anodized black for corrosion resistance
• Polyurethane differential pinion insert to reduce drivetrain deflection while keeping noise vibrations associated with such modification to a minimum
• Increased drivetrain rigidity and response
• Long-term testing performed for real-world qualification
• Full set of required torque-to-yield hardware is included to replace the bolts and nuts as recommended by Audi
