Love it!

Love this product! We use the Ultrahook on our ULTRA4 car and we love the versatility of it. Any which point you come to you have the ability to quickly attach to it. Using any type of shackle or by just hooking up to a provided winch point. It’s pretty awesome! Provides a great approach angle, because of its ability to lay flat against the fairlead, it can also take the abuse from rocks and debris hitting it. Paired with the rope gaurd it is the best hook on the market for all around use and rope protection!

Worth every PEnny

So right now I am waiting for my wife to get ready to go to the movies, (I am already ready of course). This is my second Factor 55 Ultra Hook. One is on my Jeep , and this one will go on my Power Wagon. I have been using winches on multiple vehicles, (including UTVs) for many , many years. They are the best tools to have and it seems the hooks have always been cheapo and dangerous, even with beefed up winches. THESE Factor 55 hooks are BEEFY! They are also a gorgeous work of art. I Love the detent pin to lock the hook gate. I really love how they are designed to hold and use in the “Hook Up” orientation… good move by those guys. You can snug the hook up against the fairlead instead of putting a common side bend on the cable during stowage like we’ve all done for years! I do have a few large bow shackles where the 7/8″ pin won’t fit into the closed system hole, but then I do just use the hook throat in that case. No biggie. These are WORTH EVERY PENNY.
