Prothane 8-1903 Polyurethane Motor Mount Insert Kit All Mounts Red - 4

The Prothane 8-1903 is a complete polyurethane motor mount insert kit covering all four motor mount locations for the 1988–1991 Honda Civic and CRX. Designed as a performance upgrade over factory rubber mounts, these urethane inserts press into the existing OEM mount housings, delivering a firmer, more controlled engine position without the cost of full mount replacement.

Prothane pioneered the FWD motor mount insert concept, developing a specially formulated polyurethane compound that dramatically reduces engine movement under hard acceleration and during gear changes. The result is noticeably improved throttle response, sharper shift feel, and better power transfer to the wheels — all critical gains for street performance and light track use.

Key Features:

• Complete kit — covers all 4 motor mount locations
• Precision-formulated polyurethane construction for superior durability over OEM rubber
• Limits engine movement to improve hard-start traction and shifting performance
• Reduces the risk of mount breakage under high-stress conditions
• Application-specific engineering for direct-fit installation into factory mount housings
• Available in red or black

Installation uses the existing OEM mount housings — the polyurethane inserts replace only the rubber isolator material inside, making this a cost-effective performance upgrade. Prothane's motor mount inserts are a proven solution for Honda enthusiasts seeking improved drivetrain response and engine stability.
