Prothane 14-103 Polyurethane Subframe Bushing Kit Red

The Prothane 14-103 Subframe Bushing Kit replaces worn or degraded OEM rubber subframe bushings with high-performance polyurethane, delivering improved suspension rigidity, reduced wheel hop, and enhanced chassis response. Available in red or black to suit your preference.

Why Upgrade Your Subframe Bushings?

OEM subframe bushings are typically made of rubber, which softens and cracks over time. As they degrade, the subframe loses its secure connection to the chassis, resulting in increased noise, vibration, and harshness (NVH) in the cabin, slower throttle response, and wheel hop under acceleration. Prothane's polyurethane formulation is significantly more durable than rubber and resists distortion, cracking, UV exposure, road grime, and vehicle fluids.

Key Features:

• Polyurethane construction — firmer than OEM rubber for improved handling performance and longer service life
• Available in red or black — both colors share the same durometer (hardness) and performance characteristics
• Reduces wheel hop — keeps the subframe securely located for faster, more predictable power transfer
• Includes Prothane Super Grease — pre-lube supplied for proper installation and squeak prevention
• Black variant note — black bushings contain a small amount of graphite which may further assist in reducing squeaking
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for as long as the original purchaser owns the vehicle

While a slight increase in NVH is expected compared to OEM rubber due to the firmer polyurethane material, the gains in durability and suspension performance make this a worthwhile upgrade for performance-minded drivers. Proper greasing at installation is essential to prevent squeaking.
