Review on Proform 66780 Valve Lash Wrench by John Clark

Revainrating 5 out of 5

Proform Wrench Set 66780

Proform Wrench Set 66780 Adjusting the tappets while the engine is in the car is like having three hands. With an under hood switch to reverse the engine and this great tool, adjusting the height is easier than ever. I took some photos to share and also called Proform to find out that this kit (66780) is for 9/16 inch poly lock nuts. Make sure you buy the right size, they make 4 sets of keys in different sizes. Instrument with confidence.RagenRat
