Product Features:

• PROBLEM SOLVER® GUSHER BEARING — Metal-to-metal design provides strength and allows grease to flow through bearing surface for reduced friction and long life
• STRONG AND DURABLE — Ball studs are heat treated to match or exceed OE requirements to inhibit premature failure and improve fatigue strength
• GREASEABLE SOCKET — Reduces corrosion and wear by allowing new lubricant to flush contaminants
• ABSORBS IMPACT — Belleville preload washer helps keep the bearing package tight as bearings wear
• EASY TO INSTALL — Precision tolerances for easy installation and steering alignment giving you a perfect fit right out of the box
• COMPREHENSIVE COVERAGE — Available for foreign and domestic nameplates

Delphi ball joints adhere to global OE technical requirements and undergo testing focused on strength and durability performance, safety critical tests for a safer driving experience. The ball joint push out test measures the force required to push out / remove the ball-pin from the housing. It is an important safety check to help ensure the part can withstand forces applied to the vehicle suspension system in real road conditions. The ball joint pull out test measures the force required to pull the ball-pin out from the housing. If the force required to remove the ball-pin is below the OE spec, there is a risk the joint could fail during normal driving conditions causing the vehicle to lose directional control. Additionally, Delphi’s new dust cover design features an improved Chloroprene Rubber (CR) formula that helps maintain its durability even in extreme temperatures, helping to protect the internal components and support the continued free movement of the ball joint.
