Innovative Mounts B29550-85A-BA Billet F/H-Series Conversion Engine Mount Kit 85A Grey Black Anodized

The Innovative Mounts B29550-85A-BA is a CNC-machined 6061-T6 billet aluminum conversion engine mount kit designed for H-Series and F-Series engine swaps. Featuring a premium black anodized finish and 85A grey polyurethane bushings, this kit is purpose-built for high-horsepower track and race applications. The kit includes two side mounts and one rear mount with all necessary hardware.

Unlike OEM rubber mounts that contain dampening fluid chambers prone to failure under hard use, Innovative Mounts eliminates those fluid containers entirely. The result is reduced wheel hop and sharper throttle response — a critical advantage on the track. Each mount is hand assembled and inspected before shipping.

Key Features:

• CNC-machined 6061-T6 billet aluminum construction with black anodized finish
• CAD/CAM designed and stress analyzed for maximum strength and fit accuracy
• CNC milling tolerances maintained as tight as .0001"
• No-tear tapered polyurethane bushings — solid, will never wear or break
• Tapered bushing design minimizes interference between mount and chassis
• Supports H-Series and F-Series engine swaps with manual transmission
• Also supports automatic-to-manual transmission conversions
• Includes x2 side mounts, x1 rear mount, and hardware
• Lifetime warranty
• Made in the USA

85A Grey Bushing — Track/Race Use (500+ HP):

• Designed for drivers seeking a near-solid, high-performance mount feel
• Best suited for dedicated track cars or builds with significant horsepower increases
• Provides maximum engine stability with minimal engine movement
• Some additional NVH (noise, vibration, harshness) transfer to the cabin should be expected compared to softer durometer options

Bushing Durometer Reference:

• 60A Red — Up to 250HP. Recommended for light/street driving with minimal vibration transfer
• 75A Black — Up to 500HP. Recommended for street and street/track use; standard for H/F-Series engines
• 85A Grey — 500+ HP. Designed for track cars and race applications seeking near-solid mount performance
• 95A Dark Red — Extreme/race only. Near-solid bushings with minimal engine movement

Note: This kit does not include a front mount. To complete the swap, a 92-96 Prelude H-Series timing belt post mount (Honda P/N: 11910-P13-000) is required. This kit is also compatible with T-Bracket from the 90-93 Accord DX/LX or 92-96 Prelude V6. Installation by a qualified mechanic or automotive specialist is strongly recommended.
