Below is a partial application list. The Miller 8426 valve spring tool is for some other 3.7 and 4.7's not listed below. The Miller 8426 and 8387 are very similar but work with different size valves. It's always best to check a service manual to verify which tool number is recommended.

Question - What's the difference between the 8516 and the 8387, they look practically the same?

Answer - The 8516A is a rocker arm remover and the 8387 is a valve spring remover. Some websites have their listings pictured wrong which adds to the confusion. Our pictures are correct. The rocker arm cannot be used to remove the valve springs. You can however use the valve spring remover to remove the rocker arm, but it's not easy. There is also a risk of dropping the valve keeper if trying to use the valve spring compressor when removing or installing the rocker arm. It's best to use these different tools for the purpose they were designed for to eliminate possible problems. That's why some of our customers purchase both. 

The YouTube video shows the difference between the 8516A and the 8387. Also available at WiseAutoTools.com Miller 8387.
