Innovative Mounts B49520-75A-B Billet Auto to Manual Conversion Engine Mount 75A Black

The Innovative Mounts B49520-75A-B is a CNC-machined billet aluminum auto-to-manual conversion engine mount featuring 75A durometer polyurethane bushings and a black anodized finish. Designed for Honda/Acura B-Series and D-Series engine swap applications, this mount enables a clean conversion from an automatic chassis to a manual hydraulic transmission setup.

Innovative Mounts engineers each billet mount from 6061 billet aluminum using CAD/CAM precision machining, delivering a superior fit and finish compared to stamped steel alternatives. The solid, no-tear polyurethane bushings eliminate the failure points found in OEM fluid-filled rubber mounts, providing a direct and responsive connection between the engine and chassis.

Key Features:

• CNC-machined 6061 billet aluminum construction for strength and lightweight performance
• 75A polyurethane bushing — street-oriented durometer offering an ideal balance of comfort and performance
• Black anodized finish for corrosion resistance and clean underhood appearance
• Solid, no-tear bushing design that will not degrade, crack, or compress like OEM rubber mounts
• CAD/CAM designed for precise, bolt-on fitment
• Reduces engine movement and wheel hop for improved drivetrain response
• Backed by Innovative Mounts' lifetime warranty

The 75A bushing is the most popular street choice, combining high durability with an acceptable level of NVH (noise, vibration, harshness) for daily-driven vehicles. For higher-output builds or track use, Innovative also offers 85A and 95A bushing options in compatible mounts.
