Urethane UNIVERSAL joint inserts for marine shafts | 4Boats

Urethane inserts for marine universal joints provide corrosion resistance and vibration damping for reliable shaft coupling. Suitable for driveshafts, prop shafts and yokes where urethane inserts are specified.

• Urethane construction - resists corrosion and abrasion
• Flexible interface - smooth power transfer between shafts
• Vibration damping - reduces driveline noise and shock
• Low-maintenance finish - limits routine servicing
• Suitable for saltwater use - resists galvanic corrosion
• Lightweight yet durable - maintains alignment under load

Check shaft and flange compatibility before ordering to ensure correct fitment and reliable operation. See our fitment guide for details.
