The Prothane Motion Control 13-1902-BL Prothane Motor Mounts is a high-performance engine or transmission mount designed to secure your powertrain while minimizing unwanted movement under high-load conditions. Available from GodsMods, this mount provides superior drivetrain stability compared to factory rubber mounts.

Constructed from stamped steel or billet aluminum with a high-durometer 95A polyurethane insert that resists oil, grease, and ozone degradation. The mount maintains the correct engine or transmission position within the chassis to protect cooling fan clearance, exhaust alignment, and driveline angles.

High-performance motor mounts are essential for vehicles with increased horsepower, aggressive street driving, hard launches, or off-road use where factory rubber mounts allow excessive engine movement. By locking the powertrain in place, these mounts eliminate contact with the firewall or cooling fan.

Frequently Asked Questions

Will Prothane motor mounts reduce engine vibration in my truck or muscle car?

Prothane motor mounts are designed to reduce engine vibration transfer to the chassis compared to worn factory mounts. Polyurethane Prothane mounts are stiffer than rubber but still absorb a significant amount of vibration while keeping the engine securely positioned. If you are looking for a smooth daily driver experience rubber Prothane mounts offer the best vibration isolation. For performance applications where engine stability under load is critical polyurethane is the better choice.

Will prothane motor mounts a direct bolt-in replacement for my factory engine mounts?

Prothane motor mounts are designed as direct bolt-in replacements that use the existing mounting points on your engine block and frame. No drilling, welding, or modification is needed for a proper fit on compatible vehicles. The mounts include all necessary hardware and installation instructions for a straightforward swap. Always verify that the Prothane part number matches your specific engine and chassis combination before installation.

How do Prothane polyurethane motor mounts compare to stock rubber mounts for performance?

Prothane polyurethane motor mounts are significantly stiffer than stock rubber mounts which reduces engine movement under hard acceleration and braking. This stiffness improves throttle response and shift quality by keeping the powertrain in a fixed position. The trade-off is increased vibration and noise transmission into the cabin which some drivers find noticeable at idle. For a street performance car that sees occasional track use Prothane polyurethane mounts offer the best balance.

Can Prothane motor mounts handle the torque from a high-horsepower engine build?

Yes, Prothane motor mounts are engineered to handle the increased torque output of built engines producing 400 to 800 horsepower depending on the mount design. Polyurethane Prothane mounts resist the tearing and sagging that often occurs with stock rubber mounts under high torque loads. Heavy-duty Prothane mounts feature through-hole designs or steel sleeves that prevent the mount from separating during hard launches. For extreme power levels over 800 horsepower consider solid or billet motor mounts instead.

Do I need to replace motor mounts on both sides when installing Prothane mounts?

Yes, it is strongly recommended to replace both driver and passenger side mounts at the same time when installing Prothane motor mounts. Replacing only one side can cause uneven load distribution and accelerated wear on the remaining factory mount. Both Prothane mounts should be installed and torqued with the engine at normal ride height for proper alignment. The transmission mount should also be inspected and replaced if worn to complete the full powertrain mounting system.
