Prothane 1-502BL Black Polyurethane Engine Mount Kit 6-Cylinder Pair

The Prothane 1-502BL is a black polyurethane engine mount kit designed as a direct, performance-oriented replacement for worn OEM rubber motor mounts on 6-cylinder Jeep Wrangler YJ and TJ models. Sold as a pair, these mounts are precision-engineered to provide firm, reliable engine support while resisting the flex and deterioration that commonly plague factory rubber mounts over time.

Over time, OEM rubber motor mounts crack, tear, and pull away from their mounting brackets — allowing excess engine movement that leads to increased vibration, drivetrain stress, and reduced power transfer. Prothane's polyurethane construction resists oil, chemicals, and road contaminants that would degrade rubber, offering a significantly longer service life.

Key Features:

• Sold as a pair — complete engine mount kit for both sides
• Black polyurethane construction with graphite mixed in to help minimize noise
• Firmer than OEM rubber mounts, reducing unwanted engine movement and improving power transfer to the wheels
• Resistant to oil, chemicals, and road contaminants
• Includes pre-lube grease for quiet operation — proper greasing at installation is recommended
• Precision-molded for a direct OEM-style fit — no modification required
• Backed by Prothane's lifetime warranty against defects in materials and workmanship

For best results and quiet, squeak-free operation, apply the included pre-lube grease thoroughly during installation. These mounts are an ideal upgrade for daily drivers and off-road builds alike, providing durable engine support that outlasts conventional rubber.
