Innovative Mounts 29150-75A H/F Series Steel Engine Mount Kit 75A

The Innovative Mounts 29150-75A is a CNC-machined steel engine mount kit designed for H-Series and F-Series engine swaps. Constructed from laser-cut and formed steel plates that are fitted together and welded into rigid, application-specific shapes, these mounts deliver reliable performance for both street and track builds. Each kit is finished in a durable black powdercoat prior to final assembly with polyurethane bushings.

This kit includes the 75A Black durometer bushings, which come standard on all H/F Series mount kits. The 75A rating is specifically chosen for these heavier H/F Series engines, providing the structural support needed while delivering a stiffer feel with reduced engine flex — making them ideal for street and track use in higher-horsepower applications up to 500HP.

Key Features:

• CNC-machined and welded steel construction for maximum strength and rigidity
• Black powdercoat finish for corrosion resistance and a clean appearance
• Includes 75A Black polyurethane bushings — rated for up to 500HP
• 75A bushing hardness recommended for street and track vehicles with above-average horsepower
• Reduces engine flex and improves throttle response compared to OEM rubber mounts
• Designed specifically for H-Series and F-Series engine swap applications

Bushing Options Available:

• 60A Red — Up to 250HP. Best for daily-driven street cars; minimizes vibration transfer to the chassis for a comfortable ride.
• 75A Black (included) — Up to 500HP. Standard fitment for H/F Series kits. Recommended for street and track use with above-average power output; stiffer feel with less engine flex.
• 85A Grey — 500+HP. Designed for dedicated race cars or drivers requiring maximum mount rigidity and minimal engine movement.

Please Note: This kit does not include a front mount. A separate front mount will be required to complete the swap installation.
