Prothane 14-701 Polyurethane Steering Coupling Assembly Nissan 240Z 260Z 280Z

The Prothane 14-701 is a high-performance polyurethane steering coupling assembly designed as a direct factory replacement for 1970–1978 Nissan/Datsun 240Z, 260Z, and 280Z models. Also commonly referred to as a steering rag joint or flexible steering disc, this component connects the steering column to the steering gear box and is critical for precise, responsive steering feel.

Prothane's polyurethane formulation offers a significant upgrade over the original rubber coupling, which degrades over time and introduces unwanted flex and vagueness into the steering system. The result is improved chassis feedback, more direct steering response, and a longer service life compared to OEM rubber units.

Key Features:

• Direct OEM replacement — no modifications required for installation
• Manufactured from high-durometer polyurethane for superior durability and longevity
• Reduces steering slop and improves road feedback versus worn or rubber factory units
• Resists degradation from heat, oil, and ozone exposure
• Engineered specifically for 1970–1978 Nissan/Datsun S30 chassis (240Z, 260Z, 280Z)
• Made in the USA by Prothane, a trusted name in performance polyurethane suspension components

Whether you are restoring a classic Z-car or building a performance street machine, the Prothane 14-701 steering coupling delivers the durability and driver feedback that worn OEM rubber joints simply cannot match.
