Prothane 14-1901-BL Polyurethane Motor Mount Insert Kit - Black - 4 Mount Set

The Prothane 14-1901-BL is a complete four-piece polyurethane motor mount insert kit in black, engineered as a performance upgrade for front-wheel drive Nissan Sentra applications. These urethane inserts are designed to press into your existing OEM motor mounts, filling the factory voids to dramatically reduce engine movement under acceleration and hard shifting.

Key Features:

• Complete 4-Mount Kit — covers all engine and transmission mount positions in one package
• Polyurethane Construction — significantly more durable than OEM rubber, engineered to withstand intense heat, weight, and pressure
• Black Color with Graphite Additive — graphite content helps minimize squeaking; proper lubrication with supplied pre-lube at install is recommended
• Reduces Engine Movement — fills factory voids in OEM mounts to improve power transfer efficiency from engine to wheels
• Improves Launch and Shifting Performance — limits engine rock during hard acceleration, improving traction off the line and shift feel
• Insert-Style Design — installs into your existing factory mounts; no full mount replacement required
• Lifetime Warranty — Prothane backs these inserts for the life of the original purchaser's vehicle against defects in materials and workmanship

Note: As with any motor mount insert, filling factory NVH (noise, vibration, harshness) voids may result in increased cabin vibration. This is a normal characteristic of performance-oriented polyurethane motor mount inserts and is an accepted trade-off for improved performance. Supplied pre-lube should be used during installation to prevent squeaking.
