Innovative Mounts 90550-75A K-Series Conversion Engine Mount Kit 75A Bushings

The Innovative Mounts 90550-75A is a complete four-piece conversion engine mount kit engineered for installing K-Series engines into 2001-2005 Honda Civic EM2 chassis. This comprehensive kit includes driver, passenger, front, and rear mounts with all necessary brackets, providing everything needed for a complete K-swap engine conversion.

Construction and Design:

• Laser-cut and robotically welded steel brackets for precision fitment and maximum strength
• Durable powder-coated finish for corrosion resistance
• 75A durometer polyurethane bushings designed for street performance applications
• No-tear tapered bushing design minimizes vibration transfer to chassis
• CAD/CAM engineered for optimal ground clearance and proper axle alignment

Performance Benefits:

• Eliminates fluid-filled OEM dampening containers for more direct engine response
• Reduces wheel hop and improves power transfer to the drivetrain
• 75A street bushings balance performance with daily driving comfort
• Solid polyurethane construction will never wear out or break
• Backed by manufacturer's lifetime warranty

Application Notes: This kit is designed for K20 engine specifications and requires K20 transmission. An RSX (DC5) or Civic Si (EP3) rear subframe must be used. K24 engines can be used but require additional modifications including a 2002-2006 CR-V timing belt post mount. Professional installation by a qualified mechanic is strongly recommended. Mounts cannot be returned once installed with visible bolt impressions.

The 75A durometer bushing is the most popular street option, recommended for approximately 80% of applications, providing an ideal combination of durability and comfort for spirited street driving and occasional track use.
