Prothane 6-502 Polyurethane Lower Motor Mount Insert Kit

The Prothane 6-502 is a polyurethane lower motor mount insert kit designed to reduce excessive engine movement in front-wheel-drive vehicles. Prothane pioneered the urethane insert concept for FWD performance applications, and this kit continues that tradition by providing a direct-fit solution that installs into your existing OEM motor mount housing — no need to replace the entire mount.

By limiting unwanted engine movement, these inserts help improve hard-acceleration traction and transmission shifting feel. The specially formulated polyurethane material offers significantly greater firmness and durability compared to factory rubber, helping to maintain consistent drivetrain alignment under load without transmitting excessive NVH (noise, vibration, and harshness) into the cabin.

Key Features:

• Urethane Insert Design: Fits inside the existing OEM motor mount housing — no full mount replacement required
• Improved Traction: Reduces engine torque movement during hard acceleration for better launch performance
• Sharper Shifting: Minimizes drivetrain flex for more precise, responsive gear changes
• Durable Material: Prothane's specially formulated polyurethane resists oil, grease, and heat for long service life
• Direct Fit: Engineered to OEM specifications for straightforward installation
• Kit Includes: All necessary urethane insert pieces and hardware for the lower motor mount position

The Prothane 6-502 is an ideal upgrade for enthusiasts looking to tighten up drivetrain response on their FWD vehicle without the cost or complexity of a full mount replacement. Compatible with select 2000–2004 Ford Focus applications.
