Torque converters have 2 stages, a fluid coupling that occurs first when you are starting, accelerating or pulling up a big hill. When you are cruising at a constant speed the lock up portion of the converter is engaged and 100% of each rpm is transferred through the converter, just like through a standard clutch.
We have redesigned the fluid coupling by reshaping the stator fins to achieve a higher ratio of rpm transfer through the convertor when in a fluid coupling. The lock up clutch material and surface area is enhanced to hold the high engine torque on performance Diesel engines.
Many of the models contain a new billet front cover that eliminates clutch surface warping and mounting pad weakness.
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:
UPDATE: Effective 6/1 Customer Service resumes normal business hours of M-F 8:30 – 9:00pm EST.
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.
