Review on 💪 Heavy Duty Valve Spring Compressor: OTC 4842 for Robust Compression Power by Yuan Walsh

Otc was bought by Bosch. Otc/spx is a company that makes specialty tools for GM/Ford/ and Dodge. This is a great quality product. Works great with Luv 1.4 GM engines as they are known for cracking heads. Also works very well with ls engines v8. This is a very good valve spring compressor that will work with almost anything. I've been using OTC tools for years as both Matco and Mac tools sell OTC tools by name. You can buy OTC tools here on Amazon for a lot less.
