Prothane 7-1906 Polyurethane Motor Transmission Mount Combo Kit

The Prothane 7-1906 is an application-specific polyurethane motor and transmission mount combo kit engineered to improve drivetrain control and durability over factory rubber mounts. Available in red or black, these bolt-in insert-style mounts are precision-designed for a direct, non-universal fit — delivering consistent performance for Chevrolet and Pontiac big block, small block, and 6-cylinder applications.

Key Features:

• Polyurethane construction — significantly firmer than OEM rubber, reducing unwanted engine movement and improving throttle response
• Application-specific engineering — designed for a precise bolt-in fit, not a universal application
• Limits drivetrain travel — controls engine and transmission movement to keep power transferring efficiently to the wheels
• Reduces risk of mount breakage — reinforced design handles high-stress performance driving conditions
• Poly-locked "run-safe" feature — a secondary retention design that keeps the engine secured even under extreme conditions
• Combo kit — includes both motor mount inserts and transmission mount for a complete installation
• Color options — available in red or black polyurethane to suit your engine bay preference

Prothane polyurethane mounts offer a performance upgrade over stock rubber without the harshness and noise transfer of solid steel mounts, striking the right balance between street manners and performance control. Whether you're building a weekend cruiser or a track-day machine, the 7-1906 combo kit provides the engine stability your build demands.
