The ATP MacPherson Strut Spring Compressor is built for professional technicians, automotive repair shops, and experienced home mechanics who service MacPherson struts. It’s intended for users comfortable with suspension disassembly and who will follow the tool’s safety procedures. If you lack experience with high-tension springs, seek professional assistance rather than attempting strut service alone.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use an impact driver with this compressor?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Do not use an impact driver; use a 7\/8\" (22mm) socket and hand ratchet only.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What spring size can this compressor handle?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: This compressor is designed to compress coil springs up to 300mm in length.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"ATP","offers":[{"title":"Default Title","offer_id":48084838219934,"sku":"B072QTNK74","price":40.03,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/atp-strut-compressor-front-view.jpg?v=1785863172","url":"https:\/\/northtrailauto.ca\/products\/atp-macpherson-strut-spring-compressor-forged-300mm-capacity-acme-threaded-shaft-built-in-safety-lock","provider":"North Trail Auto","version":"1.0","type":"link"}
