Prothane 6-1905 Polyurethane Motor and Transmission Mount Combo Kit

The Prothane 6-1905 is a complete polyurethane motor and transmission mount combo kit engineered to reduce unwanted drivetrain movement and maximize power transfer to the wheels. Available in red or black (-BL suffix), this application-specific kit replaces worn OEM rubber mounts with high-performance urethane components built for street and track use.

Unlike stock rubber mounts that soften and deteriorate over time, Prothane's polyurethane construction delivers the rigidity of a solid metal mount without the harshness — controlling engine and transmission torque while still isolating noise and vibration. The result is improved throttle response, more consistent shifting, and better overall driveline integrity.

Key Features:

• High-performance polyurethane construction — stronger than rubber, quieter than solid metal
• Limits unwanted engine and transmission movement to maximize power delivery
• Application-specific engineering for a precise, direct-fit installation — not a universal design
• Resistant to oil, chemicals, and road contaminants that deteriorate OEM rubber mounts
• Features internal "run-safe" interlocking design to prevent catastrophic separation under extreme use
• Available in red or black polyurethane
• Includes pre-lube for proper installation — use supplied grease to prevent squeaking
• Made in the USA
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

The Prothane 6-1905 motor and transmission mount combo kit is the ideal upgrade for performance builds where drivetrain precision and durability are a priority. Prothane recommends applying the included lubricant during installation to ensure long-term, squeak-free performance.
