Prothane 14-103-BL Polyurethane Nissan Subframe Bushing Kit Black

The Prothane 14-103-BL is a polyurethane subframe bushing kit designed to replace worn or degraded OEM rubber subframe bushings. Located at the critical mounting points between the subframe and the vehicle chassis, these bushings play a key role in securing the subframe and reducing noise, vibration, and harshness (NVH) from entering the cabin.

Stock rubber subframe bushings deteriorate over time — cracking, hollowing out, and eventually failing to hold the subframe securely. This allows unwanted subframe movement that can affect steering precision, drivetrain alignment, throttle response, and overall handling. Prothane's high-performance polyurethane material is significantly more durable than OEM rubber and resists the cracking and rotting that leads to premature failure.

Key Features:

• High-performance polyurethane construction — outlasts OEM rubber bushings
• Black urethane finish provides an OEM-style look under the vehicle
• Complete kit includes 12 bushings — covers 4-door applications (left and right sides)
• Graphite-blended black urethane compound helps minimize squeaking
• Firmer than stock rubber for improved subframe rigidity and handling feedback
• Designed and tested by enthusiast engineers for on- and off-road use
• Lifetime warranty against defects in materials and workmanship for the original purchaser

Prothane's polyurethane bushing material strikes the ideal balance between the rigidity of solid metal mounts and the flexibility of stock rubber, reducing subframe movement without the harshness of a full solid-mount setup. Pre-lube is included — proper lubrication at installation is recommended to ensure long-term, squeak-free performance.
