None of that CCA (copper-clad aluminum) that's used in inferior products, or stereo installations. We only use fine-strand, SAE (Society of Automotive Engineers) approved, pure copper cable. Then using a powerful electromechanical crimping machine, we crimp each solid-copper end, and finally finish the construction by adding a environmental seal made of marine grade heatshrink meeting MIL-I-23053\/4. Also included are military style corrosion resistant battery connections and a MEGA fuse and holder. To make the entire install simpler, every end will be labeled for ease of installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need a bigger alternator to run these cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Every vehicle can benefit from our \"better than factory\" cables. The years, along with environmental damage from rain\/salt water\/corrosion, can greatly impact your electrical system. Our customers have consistently reported that their vehicle starts faster, charges the battery better, and many times cured electrical gremlins that were brought on by compromised wiring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eI've changed my mind!

These all require more amperage than the stock alternator is capable of providing. Maybe you're not running any of these yet, but considering it, these cables will get you ready ,\u003ca href=\"https:\/\/www.big7kits.com\/products\/ford-powerstroke-7-3-diesel-f250-f350-obs-1990-1997\"\u003e\u003cstrong\u003e Ford Powerstroke 7.3 Diesel - F250\/F350 OBS Battery Cable Kit\u003c\/strong\u003e\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2GA or 4GA?
