- Precision-engineered fit: assemblies are built to exact fit and include the additional components needed to restore all wearable parts to original condition.
- Rated for high pressure: the pressure hose exceeds original-equipment performance standards with a 1,500 psi max working pressure, an 8,700 psi burst rating, and 1,600 lb tensile strength for durability.
- Factory-tested: every pressure hose is subjected to a high-pressure quality-assurance test before leaving the factory for trouble-free installation and operation.
If cracked, chafed, or leaking power-steering lines are the cause of your fluid loss, whining, or hard steering, this assembly replaces them on the hydroboost-to-gear position.
