Innovative Mounts 18750-85A B-Series Steel Conversion Engine Mount Kit 85A

The Innovative Mounts 18750-85A is a CNC-machined steel conversion engine mount kit designed for B-Series engine swaps into the 1984–1987 Honda Civic and CRX (AF/AH/EC chassis). Engineered with CAD/CAM design and stress analysis, this kit delivers a precise, bolt-on fit compatible with B16, B17, B18, and B20 engines paired with a manual cable transmission. Unlike many competing kits, it requires no notching or trimming of the hood and clears even B20 engines. The steel construction features a durable black wrinkle powdercoat finish and high-quality welds throughout.

This kit ships with 85A Grey bushings, Innovative's firm-durometer option rated for 400–500HP applications. The 85A durometer is intended for performance street and track builds where minimizing engine flex and maximizing drivetrain response is the priority. All kits use Innovative's unique no-tear, vibration-minimizing bushing design. Kit uses stock/OEM hardware for straightforward installation.
