Weak. Small piston, thin case, and a bad habit of giving up when you add bigger tires or a locker.

You’ll need the right hoses, maybe a little steering shaft work, and in some cases a 1\" body lift for clearance. But once it’s in, you’ll have a steering gear that can handle real trail abuse without crying uncle.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThis is a conversion.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIt’s not a 30-minute swap.
