Review on 🔧 Yoursme 66784 Stud Mount Valve Spring Compressor for 3/8" & 7/16" Rocker Studs - Remove & Install Valve Spring by Dante Jeppi

This valve spring compressor is great for replacing valve springs without removing cylinder heads, using compressed air to hold valves in place. Works with 7/16" and 3/8" rocker pins. Looks and works the same as a better brand spring compressor. They're both made in China, so who knows, maybe they're from the same factory. It remains to be seen how well they perform when used with extremely stiff cam-level full roller springs.
