XDP continues to closely monitor the COVID-19 (Coronavirus) outbreak. As an integral part of the automotive supply chain, at this point all call centers and distribution centers remain fully operational to ensure we keep vital service components flowing to vehicles used in transport of goods and emergency response. To ensure the health of our employees, families, and customers, we have made the following procedural changes:
Effective 3/16 we have shifted Customer Service hours to 8:30 – 7:00pm EST. To ensure compliance with New Jersey’s recent curfew.
Effective 3/18 we have decided to temporarily close both of our retail stores in NJ and NV.
Our technical sales team remains available Mon-Fri 8:30am-9pm and Saturday 10:30am-7pm EST.
