Pioneer Automotive 615531 Hydraulic Engine Mount

The Pioneer Automotive 615531 is a hydraulic engine mount (motor mount) engineered as a direct OE replacement to restore proper engine support and isolate noise, vibration, and harshness (NVH) in the vehicle cabin.

Hydraulic engine mounts use a fluid-filled chamber to deliver superior vibration damping compared to standard rubber mounts, making them ideal for applications where OEM hydraulic mounts were originally installed. This mount is a direct drop-in replacement designed to match original equipment geometry and mounting points.

Key Features:

• Hydraulic design — fluid-filled chamber provides enhanced vibration absorption over standard rubber mounts
• Sure-Fit System — application-tested on vehicle-specific fixtures for a hassle-free, precise installation
• OE-matched specifications — manufactured to original equipment standards to restore proper engine positioning and operation
• High-grade metal housing — corrosion-resistant coating or pure aluminum casting for long-term durability
• Chemlock rubber-to-metal bonding — superior bond between rubber compound and metal bracket for lasting integrity
• Premium rubber compound — blended natural and SBR (Styrene-Butadiene) rubber formulated for maximum vibration damping and service life
• Grade #5 hardened steel fasteners — where included, for reliable clamping strength
• 100% tested — each mount undergoes quality control throughout the manufacturing process

Pioneer Automotive Industries has been producing premium powertrain components since 1946. This hydraulic engine mount is a reliable, quality-tested solution for restoring OE ride quality and protecting the drivetrain from excessive engine movement.
