Prothane 1-1905 Jeep Polyurethane Motor & Transmission Mount Kit

The Prothane 1-1905 is a complete polyurethane motor and transmission mount kit engineered as a direct replacement for worn factory rubber mounts on compatible Jeep models. Designed specifically for the 360 c.i. 8-cylinder engine, this kit addresses the common failure of OEM rubber mounts, which tend to deteriorate over time from oil exposure, heat, and road contaminants — resulting in excess drivetrain movement, unwanted noise, and loss of power transfer.

Prothane's polyurethane construction delivers firm, precise engine and transmission support, keeping the driveline properly aligned and reducing torque wrap. Unlike soft rubber mounts that allow the engine and transmission to shift under load, these mounts limit unwanted movement to help put more power to the wheels. The material is highly resistant to oil, chemicals, and road contaminants that would normally break down a rubber mount.

Key Features:

• Polyurethane construction — resists oil, chemicals, and road contaminants that deteriorate rubber
• Run-Safe metal interlock — internal interlocking steel design maintains mount integrity even under extreme stress
• Application-specific engineering — designed to match OE specifications for proper fitment, not a universal design
• Controls torque and driveline movement — limits engine and transmission shift for improved power delivery
• Includes mounting hardware — complete kit includes all necessary nuts, bolts, and washers for installation
• Available in red — black version available under part number 1-1905-BL
• Fits 360 c.i. 8-cylinder models only — for transmission mount only, see Prothane part 7-1604

Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser, the 1-1905 is a long-lasting upgrade over factory rubber mounts. For six-cylinder applications or transmission-only replacement, see the related Prothane Jeep mount lineup.
