DenLorsTools.com Summary: Automotive repair blog and video comparing two Miller specialty tools. We have had a lot of questions regarding the Miller 8387 Valve Spring Compressor and the 8516A Rocker Arm Remover/Installation Tools. Both look similar and are for use on Dodge and Jeep 3.7 and 4.7 liter engines. These motors are commonly used in Jeep Liberty, Dodge Durango, Dodge Dakota, Jeep Grand Cherokee etc. *Note – The 8516 has been updated and the newest number has an “A” on the end now making it 8516A.
