Universal Overhead Valve Spring Compressor Tool

This is the tool I personally use to do valve springs IN THE CAB on a 7.3 Power Stroke.

You must make sure that the PISTON is at TDC while working on EACH cylinder. 

Spend $100 and rent this tool. If you don't return it, no big deal. If you do return it, we will refund you $50. 

You are responsible for shipping both ways.
