Prothane 13-504 Rear Engine Mount Insert Kit Red/Black

The Prothane 13-504 is a rear engine mount insert kit designed for the 1995–1999 Mitsubishi Eclipse and Eagle Talon (Turbo and Non-Turbo, AWD and FWD). Rather than replacing the entire mount, these precision-engineered polyurethane inserts fill the voids built into your OEM motor mount, significantly reducing engine movement under acceleration and load.

Stock rubber motor mounts are designed to absorb noise and vibration, but over time—or under hard driving conditions—the rubber degrades and allows excessive engine movement. This translates to sluggish throttle response, reduced power transfer, and drivetrain misalignment. The Prothane 13-504 solves this by replacing the soft OEM rubber void-fill with specially formulated polyurethane that holds its shape under stress, heat, and exposure to engine fluids.

Key Features:

• Polyurethane construction — far more durable than OEM rubber, resistant to heat, oil, and road chemicals
• Insert-style design — works with your existing OEM motor mount housing; no full mount replacement required
• Reduces engine movement to improve hard-launch traction and shifting performance
• Application-specific engineering — not a universal fit; designed precisely for the 95–99 Eclipse/Talon platform
• Available in Red or Black
• Made in the USA
• Backed by Prothane's Lifetime Warranty

Ideal for performance-oriented drivers looking to maximize power delivery and drivetrain stability without the harshness of solid metal racing mounts. The Prothane 13-504 is a cost-effective upgrade that keeps your engine firmly planted where it belongs.
