Additional information

Dodge Ultraserts can be installed using ultrasonic equipment (moderate to high production) or thermal installation equipment (prototype work and low quantity production). Thermal equipment can be as simple as a soldering iron held by hand or mounted in an arbor or drill press. More refined equipment is available with adjustments and settings for precise uniform installations.
